According to the U.S. EPA and Dow Chemical MSDS the BP is 121.1 C. not the 147 value previously claimed. I do not know which value actually corresponds to ultra-pure 1,1,2,2 tetracholor ethylene at STP (if either) but I'd go with 121C

A quick look indicates that most sources seem inclined to agree with the 121.1°C figure. -- Grunt 14:34, 2004 Jun 17 (UTC)

Molecular weight - error ?

MW shown as 131.4 amu looks wrong. Should be 165.83 I think. user jpl

147 value it is. When it reach 154 we talk serious. — Preceding unsigned comment added by 80.213.34.117 (talk • contribs)

Possible schizophrenia risk factor

"Tetrachloroethylene exposure and risk of schizophrenia: offspring of dry cleaners in a population birth cohort, preliminary findings." (PMID 17113267). Population sample is big, but the results are not replicated by another study yet. Would it be pertinent to add this to the article? Also look here: Dry Cleaning Chemical Linked to Increased Schizophrenia Risk. Best regards, CopperKettle 06:45, 20 April 2007 (UTC)[reply]

Sorry for the mess. I remember that zoots.com has a study on their website about the problems with perc. Good article up to now. -M —Preceding unsigned comment added by 130.115.99.226 (talk) 15:31, 19 September 2007 (UTC)[reply]

PCE isn't TCE

"Tetrachloroethylene contamination was used as a plot focus in a story arc of the TV show Ghostwriter. Its health risks are also discussed in A Civil Action, which involves a Woburn, Massachusetts, lawsuit where a cluster of leukemia developed, arguably due to high perc levels. It has been featured in an episode of Stargate SG1."

This is in the wrong place. Trichloroethylene was found in the Woburn water (TCE), not tetrachloroethylene. I'm getting rid of it. CaTigeReptile 20:06, 9 May 2007 (UTC)[reply]

The statement is partially correct and partially incorrect, but the decision was wrong. Both TCE and PCE were found in the Woburn water. If you find PCE in soil or groundwater, you will typically also find its breakdown products, TDE, DCE, and VC (Vinyl Chloride).

Why does the article insist on using the outdated nomenclature?

It should be revised to consistently use the IUPAC name of tetrachloroethene, with all of the other names listed among the "other names" sections.
