Cerimetry

Hi Rifleman, good job for the chemistry articles! Would you mind taking a look at the very first article I just have created on Cerimetry? It is still a temporary subpage (not published yet); I've just created the page today. Your contribution would be appreciated. Thanks a lot in advance, Burgundy111 —Preceding undated comment added 23:40, 6 May 2011 (UTC).[reply]

Very nice, great work! I think it's ready to go live. You can use the "move" function on top to move it onto the mainspace. Just a thought - for a relatively established procedure, perhaps you can find one or two general references which talk about it? Some reference text, possibly focused on analytical chemistry? --Rifleman 82 (talk) 03:08, 7 May 2011 (UTC)[reply]

Please be more careful...

when you remove unreferenced material. When you removed unsourced material from Cadmium stearate you removed the referenced part "It is carcinogen". Sorry that the message was very late. ~~EBE123~~ ^talk_Contribs 20:15, 9 May 2011 (UTC)[reply]

That it is a carcinogen is not particularly notable. The state of New Jersey is not really an authority with regard to a compound's carcinogenicity or lack thereof. If anything, that nugget should go into the chembox. We tend not to have such standalone sections unless there is really something to say. --Rifleman 82 (talk) 23:12, 9 May 2011 (UTC)[reply]

Componds templates

Hi Rifleman 82,

I am not a chemist. I have just occasionally found that there are some elements left behind, without relevant compound templates. So, I have just mapped the empty space by copypasting :)) That was my sole motivation. I would be happy if a professional chemist have these new patterns checked. IMHO, yes, some formulas are too long, and names would be more useful.

Cheers from Moscow, Lamro (talk) 04:58, 13 May 2011 (UTC) 04:54, 13 May 2011 (UTC)[reply]

Thanks for getting back. I'll go take a look this weekend. --Rifleman 82 (talk) 14:04, 13 May 2011 (UTC)[reply]

Templates

Hi there,

I keep on creating compound templates for rare elements and have mixed links among the following:

May you restore correct links for first two ones and delete the last ones? I need help.

Cheers, Lamro (talk) 12:41, 14 May 2011 (UTC)[reply]

I think I got it. Let me know if you need anything. --Rifleman 82 (talk) 16:53, 14 May 2011 (UTC)[reply]

Pls, delete Template:Re compounds and Template:Ro compounds. Lamro (talk) 21:00, 14 May 2011 (UTC)[reply]

What's the problem with {{Re compounds}}? --Rifleman 82 (talk) 21:29, 14 May 2011 (UTC)[reply]

According to [Category:Chemistry compounds templates], the proper template name should be {{Rhenium compounds}}. Therefore, {{Re compounds}} should be deleted. Pls, make sure that the content is reallocated to {{Rhenium compounds}}. Thanks for sorting out the mess that I have occasionally created. Best regards! Lamro (talk) 07:21, 15 May 2011 (UTC)[reply]

Thionyl chloride image deletion

This MSDS ([1]) states that SOCl₂ can be yellow or even reddish. Why did you delete the picture of yellowish thionyl chloride in a vial? --Chemicalinterest aka 98.221.179.18 (talk) 22:10, 22 June 2011 (UTC)[reply]

Preparation of BCDMH.png

It looks like there is an error in File:Preparation of BCDMH.png which you created. The central structure should not have the chlorine atom in it. Can you please correct it? Thank you. ChemNerd (talk) 18:44, 4 July 2011 (UTC)[reply]

Also, I wonder if maybe the order of reaction is incorrect. It seems to me that using a weak base such as K2CO3 in the first step would lead to reaction at the more acidic imide nitrogen, and then the second reaction at the less acidic amide nitrogen would require the stronger base NaOH. As the reaction is drawn, I would expect to get an isomeric product. What do you think? ChemNerd (talk) 18:49, 4 July 2011 (UTC)[reply]

Thanks for dropping me a note. Yes, I made a mistake in the first reaction product. I don't disagree with your reasoning, but let me check again in the morning. --Rifleman 82 (talk) 03:48, 6 July 2011 (UTC) I've fixed the error in the image. I've looked at Ullmann's again, and its cited article [2], and indeed the bromination occurs at the amide nitrogen before the imide. --Rifleman 82 (talk) 22:02, 13 July 2011 (UTC)[reply]

Thanks for fixing the image, and thanks for taking the time to double check the reference. There seems to be something wrong with the way the image displays though. In both the thumbnail and in the larger image displayed at BCDMH, I still see the older version, and not the corrected one. I tried clearing my browser's cache, and also appending "?action=purge" to the url and reloading (both the article page and the image page on Commons) but nothing seems to help. Any ideas? ChemNerd (talk) 19:02, 14 July 2011 (UTC)[reply]

Quick and dirty method: I changed the image width and it re-drew the image in the cache. --Rifleman 82 (talk) 19:15, 14 July 2011 (UTC)[reply]

There's a known bug in the thumbnailer related to new revisions of images uploaded to existing-image filenames. Tech folks are working on it. DMacks (talk) 19:18, 14 July 2011 (UTC)[reply]

It looks fine in the article now, which is all that matters at this point I guess. ChemNerd (talk) 20:51, 14 July 2011 (UTC)[reply]

Pls, review the new article

Hi! I have created a new article about the chemical reaction of transalkylation. I am not a chemist but happened to be involved in a large-scale petrochemical project. The reaction is employed to manufacture p-xylene from BTX blend of hydrocarbons. I know from my previous interaction with you that you are a chemistry expert. May I ask you to review the stub? With best wishes, Lamro (talk) 08:56, 13 July 2011 (UTC)[reply]

I am not an expert, but I've taken a look and tweaked it a little. I don't think that patents are the best references for this technology. I'll look at it again if I have more time. --Rifleman 82 (talk) 21:59, 13 July 2011 (UTC)[reply]

Selectfluor

Rifleman 82 - thanks for the tweaks to the Selectfluor page, to recognize the Air Products trademark. I would like to make more edits to the page to list the proper patents for both the composition and applications, however I'm not well versed in Wikis. As you can proablay see this was the first edit I've ever made - one has to start somewhere. I work for Air Products and we want correct, complete, and accurate infromation on Wikipedia regarding our products. Any suggestions on first step?

One last thing is there a way to add the (R) to the title? I could not find the symbol in the availabe options. Thanks

Caligijg (talk) 20:02, 4 August 2011 (UTC)[reply]

We don't use the TM or R symbols in Wikipedia (MOS:TM). Unless the patent discloses how this product is manufactured, and is thus used as a reference, I don't think it needs to be included. Patents tend to be rather speculative; we prefer secondary sources like books and review articles which can provide more context. --Rifleman 82 (talk) 21:00, 4 August 2011 (UTC)[reply]

It's great that your company is interested in contributing to Wikipedia, do take a look at WP:COI. For example, you are encouraged to explicitly state your affiliation on your user page, to be upfront about it. You will also need to be very careful about how you edit, to avoid any accusations of bias or promotion. --Rifleman 82 (talk) 21:03, 4 August 2011 (UTC)[reply]

Nickel carbonyl

Of course you're right that there are many metal carbonyls. Nickel is the only volatile one at 50 C, and I have the distinct feeling that some iron carbonyl is formed if the temp gets too high, and lowers the purity of the nickel. It turns out to be a very complex subject and Mond investigated all kinds of carbonyls in the 1890s. Thanks for keeping it honest-- there should be some simple way of putting this, as soon as I find out if the iron carbonyl is formed but not vaporized, or if there's something about the kinetics at 50 C that keeps much of it from being formed at all. S B H arris 14:38, 26 August 2011 (UTC)[reply]

I've made some changes. Tell me what you think? --Rifleman 82 (talk) 19:49, 26 August 2011 (UTC)[reply]

Pretty important discussion on template

I left a similar message on Materialscientist, but I think that the discussion at Wikipedia talk:WikiProject Chemicals is fairly important and that experienced editors should comment so that we can revise or recommit to our manual of style.

If you have the time... --Smokefoot (talk) 10:37, 14 September 2011 (UTC) Thanks for pointing this out. --Rifleman 82 (talk) 03:49, 15 September 2011 (UTC)[reply]

Coffee furanone

ADDED NOTE: NEVER MIND IT HAS JUST BEEN FIXED!

Dear rifleman82, The structure of Coffee furanone (2-methyltetrahydrofuran-3-one) in the ChemBox is wrong. can you fix please?. The keto and methyl groups should change places. This is not a lactone, but a cyclic keto ether. It is a derivative of 2-methyltetrahydrofuran with a keto group in the 3-position (meta to the oxygen of the ring). — Preceding unsigned comment added by George.kvakovszky (talk • contribs) 22:56, 8 December 2011 (UTC)[reply]

Boron thing

Hi and thanks for the cooperation on various articles lately. For some reason, the author of the hydroboration article is reverting. This editor does not understand that he/she does not own the article. Most likely they are upset that their work was redistributed around various other places, perhaps because this is a school assignment (my guess). I have tried to communicate with him/her, to not effect. So please join me in monitoring Hydroboration–oxidation reaction, Hydroboration, and Metal-catalysed hydroboration. My main message is to thank you though.--Smokefoot (talk) 22:06, 16 December 2011 (UTC)[reply]

Transition metal oxo complex

I am not sure if I can make this change by cut and paste, so I wanted to check with you and ask your help. I propose a noncontroversial change of Oxo ligand to Transition metal oxo complex, which is a redirect to the former. We have a number of articles entitled "Transition metal ... complex" so this shift seems logical. Thanks for your continuing help around here.--Smokefoot (talk) 23:54, 2 February 2012 (UTC)[reply]

I'll move the article. I've written an article or two on "metal ... complex", such as metal salen complex and metal bis(trimethylsilyl)amide, etc. I imagine oxo complexes of main group elements are rare, and there are other "TM ... complex" articles too. I'm wondering if those "TM ... complex" articles should eventually be moved to "metal ... complex". --Rifleman 82 (talk) 00:27, 3 February 2012 (UTC)[reply]

Yes, I wondered the same thing. We could create "main group salen." I figured the best way would be to base the title on the main theme, then mention in a section "related classes of compounds", e.g. the main group salem derivatives. Thanks for your help and comments. --Smokefoot (talk) 06:10, 3 February 2012 (UTC)[reply]

ASEAN kecil

the concept of ASEAN kecil seems not to have been much more than a (good?) idea. I couldn't find anything substantial on it now so I have PRODed it... As always: feel free to remove if you think it is notable... Cheers! L.tak (talk) 18:25, 11 February 2012 (UTC)[reply]

I agree it is a poorly defined, little-discussed term, but it still crops up every now and then, e.g. [3]. I thought of how to incorporate it in ASEAN but it doesn't seem to fit well without more references. I'll just redirect it. Redirects are cheap, and it is not an unhelpful redirect. --Rifleman 82 (talk) 19:45, 11 February 2012 (UTC)[reply]

MSU Interview

Dear Rifleman 82,

My name is Jonathan Obar user:Jaobar, I'm a professor in the College of Communication Arts and Sciences at Michigan State University and a Teaching Fellow with the Wikimedia Foundation's Education Program. This semester I've been running a little experiment at MSU, a class where we teach students about becoming Wikipedia administrators. Not a lot is known about your community, and our students (who are fascinated by wiki-culture by the way!) want to learn how you do what you do, and why you do it. A while back I proposed this idea (the class) to the community HERE, where it was met mainly with positive feedback. Anyhow, I'd like my students to speak with a few administrators to get a sense of admin experiences, training, motivations, likes, dislikes, etc. We were wondering if you'd be interested in speaking with one of our students.

So a few things about the interviews:

Interviews will last between 15 and 30 minutes.
Interviews can be conducted over skype (preferred), IRC or email. (You choose the form of communication based upon your comfort level, time, etc.)
All interviews will be completely anonymous, meaning that you (real name and/or pseudonym) will never be identified in any of our materials, unless you give the interviewer permission to do so.
All interviews will be completely voluntary. You are under no obligation to say yes to an interview, and can say no and stop or leave the interview at any time.
The entire interview process is being overseen by MSU's institutional review board (ethics review). This means that all questions have been approved by the university and all students have been trained how to conduct interviews ethically and properly.

Bottom line is that we really need your help, and would really appreciate the opportunity to speak with you. If interested, please send me an email at obar@msu.edu (to maintain anonymity) and I will add your name to my offline contact list. If you feel comfortable doing so, you can post your name HERE instead.

If you have questions or concerns at any time, feel free to email me at obar@msu.edu. I will be more than happy to speak with you.

Thanks in advance for your help. We have a lot to learn from you.

Sincerely,

Jonathan Obar --Jaobar (talk) 07:26, 12 February 2012 (UTC)[reply]

methyl salicylate

From what I read yesterday before doing my edits, methyl salicylate and salicylic acid are two of several salicylates. So I undid a bit of your useful editing. But I'm not a chemist and havent even taken orgo. If you're confident you're right, feel free to override me.--Elvey (talk) 02:04, 3 March 2012 (UTC)[reply]

Thanks for your note. Salicylate can refer to the anion, or to the esters. In the body, I don't expect much free acid (salicylic acid), as opposed to the salicylate anion. They all work similarly, I believe. I'm not opposed to your edit, I was just trying to avoid being overly specific. --Rifleman 82 (talk) 03:35, 3 March 2012 (UTC)[reply]

Ah, got it. So s/salicylic acid/salicylic anion/ would be an improvement then? Or if you know that all salicylates are roughly equivalent NSAIDs then I guess a straight revert of my last edit would be in order? --Elvey (talk) 21:59, 3 March 2012 (UTC)[reply]

Bromobenzene

Can you please intervene on bromobenzene? Otherwise we have a revert war. I am an open-minded person, but the user is unloading a ton of very specialized material, much of which appears to be copied or nearly copied from a book edited by an author with a similar name. And the material is just far to detailed for an encyclopedia. The editing is being done by both unregistered user and others, probably the same person.

Technical questions about ChemSketch

Hi it's me again! Actually I just want to know how to produce high quality images from ChemSketch (mine are always blurred and boxed), so can you please instruct me about that? Thanks a lot!

LHcheM (talk) 16:00, 27 April 2012 (UTC)[reply]

You can start by clicking Options --> Set drawing style --> ACS

This will give you bond lengths, widths, and font sizes that are more commonly used (ACS = suitable for ACS publications).

When you export PNGs, File --> Save as --> Portable network graphics --> Options --> Image resolution: 720 dpi.

This makes a very big image, but when scaled down, it is of good quality. Let me know how it goes. --Rifleman 82 (talk) 16:23, 27 April 2012 (UTC)[reply]

Functional group numbering convention

Regarding the transesterification reaction image (nice image, btw), I was taught that the "R" functional group numbers should be a subscript (prime notations are superscripts, obviously), and I've seen this convention followed consistently on Wikipedia (e.g., Functional group). I'm unsure if there is an official (IUPAC) convention, as I searched but could not find it, or if both sub and sup are acceptable. As you're professional chemist, you know far more about this topic, but I wanted to make certain this wasn't a minor oversight.--E8 (talk) 18:17, 24 October 2012 (UTC)[reply]

Thanks for your comments. I did it in line with Wikipedia:Manual_of_Style/Chemistry/Structure_drawing (third point of the "general" section; subscripted numerals might be confused with the stoichiometries of the groups. If you observe the literature, this notation is gaining in popularity, though both are completely acceptable in my opinion. --Rifleman 82 (talk) 19:24, 24 October 2012 (UTC)[reply]

I learn something new every day - thanks.--E8 (talk) 01:37, 25 October 2012 (UTC)[reply]

(talk page stalker) It's also consistent with IUPAC's 2008 drawing standards. "GR-9.1 Small substituents" states, "Traditionally, the letter “R” is widely used, followed by a superscripted number (R¹, R², etc.) or prime(s) (R', R", etc.) if necessary to distinguish different groups. It is not acceptable to use a letter followed by a subscripted number, since subscripted numbers are more commonly used to indicate repeat counts, and confusion between the two is inevitable."

Apollo 11, and sodium hypochlorite vs. hypochloride

Just about a year ago, this question came up and the discussion got archived. Even though there's no article here on hydrochloride, I did some Google searching and concluded there actually was such a thing, which is also used as a disinfectant. Since I see you're a chemist, can you help shed some light on whether some people are just mistaking the name, or could the other term be correct? Talk:Apollo 11#Crew decontamination: hypochlorite or hydrochloride? Thanks. JustinTime55 (talk) 18:24, 2 November 2012 (UTC)[reply]

File:Remsen-Fahlberg synthesis of saccharin.png

Hi Rifleman. Can you please make a few corrections to this image? In three of the structures (top center, top right, bottom center), there are too many oxygens on the sulfur atoms. Thanks. -- Ed (Edgar181) 14:42, 9 November 2012 (UTC)[reply]

Done. Would you like to check? Thanks. --Rifleman 82 (talk) 16:59, 9 November 2012 (UTC)[reply]

Looks good. Thanks for the quick fix. -- Ed (Edgar181) 18:10, 9 November 2012 (UTC)[reply]

Gossypol

Hi, I'm curious: You fixed the gossypol structure within an hour of my making a request to do so. Did you come across it randomly or have you set it up somehow such that you get relevant notifications, and, if so, what, e.g., all changes to talk pages to articles that have chemical structures?HowardJWilk (talk) 01:44, 18 November 2012 (UTC) I just tried to put my comment under a heading with two equal signs and a space before, and a space and two equal signs after, but it didn't take: The preview showed exactly that: Two equal signs...etc. How do you do it?HowardJWilk (talk) 01:52, 18 November 2012 (UTC)[reply]

Gossypol is on my watchlist. You can check yours too: Special:Watchlist. By default, all pages that you have edited are on your watchlist, and you can keep track of changes to those articles that way.

You can insert a header with two equal signs on each end. For example,

==header==

Naming convention

As a chemist, you are far more experienced than me, so I ask you. I moved Tantalum(V) ethoxide to Tantalum pentaethoxide, per this guideline: "Compounds with a substantial degree of covalency should be named by stoichiometric nomenclature: hence titanium tetrachloride not titanium(IV) chloride", taken from WP:CHEMNAME. Is it correct? You are free to revert if my move is not within the guideline and leave an explanation here so that I don't make a mistake again. Thanks. — ΛΧΣ21™ 16:40, 22 November 2012 (UTC)[reply]

Either are fine, but there were two parallel articles on this topic so I picked one that seemed to describe the stoichiometry better (Ta has lower oxidation states too). I'd stick with tantalum(V) ethoxide for now at least, because the pentaethoxide name is less common. I'm trying to find the crystal structure of this compound. Alkoxides often form dimers and oligomers so I'd like to confirm its structure. --Rifleman 82 (talk) 16:46, 22 November 2012 (UTC)[reply]

Oh, thanks for the explanation. I will move it again to where it was, although I will keep using "Tantalum pentaethoxide" on the did you know nomination. You may take a look and review it, if you wish. Thanks again. — ΛΧΣ21™ 16:59, 22 November 2012 (UTC)[reply]

Replaceable fair use File:Philip Yeo.jpg

Thanks for uploading File:Philip Yeo.jpg. I noticed the description page specifies that this media item is being used under a claim of fair use, but its use in Wikipedia articles fails the first non-free content criterion in that it illustrates a subject for which a freely licensed media item could be found or created that provides substantially the same information or which could be adequately covered with text alone. If you believe this media item is not replaceable, please:

Go to the file description page and edit it to add {{di-replaceable fair use disputed}}, without deleting the original replaceable fair use template.

Dichlorodifluoromethane

The RPhrases and SPhrases where changed. They do not match any MSDS that I have seen (most do not list S/R Phrases) and do not match the German de:Dichlordifluormethan, nor the French fr:Dichlorodifluorométhane Phrases (the fr & de sites do match each other but do not give a source that I see). I added a request for clarification to the editor's talk page who did not reply. I noticed that your request was deleted. Seems to be other unsourced changes as well. Suggestions? Thank Jim1138 (talk) 08:38, 2 December 2012 (UTC)[reply]

Thanks for bringing it to my attention. Some of his edits may be right, but many are strange or questionable. It is disruptive that we are forced to check every single of his edits. I don't think he should edit further until he communicates. --Rifleman 82 (talk) 19:30, 2 December 2012 (UTC)[reply]

Nb(OEt)5 etc

I sometimes move very fast on rewriting these moronic articles forced upon us. I noticed after doing my thing on niobium ethoxide that you had edited there too. For various reasons, I know where the good literature is. Just say the word and I will excavate your edits, which I am sure were a great improvements. Again, let me know if I blew it. --Smokefoot (talk) 16:14, 2 December 2012 (UTC)[reply]

Your version is great. I just tried to tidy up what they had, one of many others all at once. You actually wrote the article, so there's no reason to reinstate mine. Thanks for cleaning up the mess. --Rifleman 82 (talk) 19:25, 2 December 2012 (UTC)[reply]

Please set an expiry date for dy11111's block

I am on my computer now. I would please like you to set an expiry for the block you placed on my account, Dy11111. I have learned my lesson now, and I would like to be unblocked later. It would be greatly appreciated! Please leave a message on Dy11111's talk page.

76.226.62.198 (talk) 00:32, 5 December 2012 (UTC)[reply]

I'm open to that, but first, tell me what lesson you've learned? --Rifleman 82 (talk) 14:59, 5 December 2012 (UTC)[reply]

I would also suggest, as a condition of unblocking, that Dy11111 agree not to edit while logged out because of his history of using multiple IPs to edit war on various articles. Unblocking Dy11111 and having him edit with only that account would be preferable to the current situation where the (potentially disruptive) editing is hard to monitor. ChemNerd (talk) 16:10, 5 December 2012 (UTC)[reply]

I agree with ChemNerd - not only were Dy11111's edits usually unhelpful, they were made deceptively. --Smokefoot (talk) 18:41, 9 December 2012 (UTC)[reply]

I promise to edit in a non-disruptive way. You may block my IPs, but please leave my account unblocked. 76.226.62.198 (talk) 20:02, 5 December 2012 (UTC)[reply]
