'''1,2-Diaminocyclohexane''' ('''DACH''') is an [[organic compound]] with the formula (CH<sub>2</sub>)<sub>4</sub>(CHNH<sub>2</sub>)<sub>2</sub>. It is a mixture of three [[stereoisomers]]: ''cis''-1,2-diaminocyclohexane and both [[enantiomer]]s of [[trans-1,2-Diaminocyclohexane|''trans''-1,2-diaminocyclohexane]]. The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH. |

1,2-Diaminocyclohexane (DACH) is an organic compound with the formula (CH2)4(CHNH2)2. It is a mixture of three stereoisomers: cis-1,2-diaminocyclohexane and both enantiomers of trans-1,2-diaminocyclohexane. The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH.
Manufacture
[edit]The product is available commercially, manufactured by the hydrogenation of o-phenylenediamine. The two trans enantiomers can be resolved by conversion to diastereomeric salts of various chiral acids.[1]
Uses
[edit]The product is an epoxy curing agent for use in Coatings, Adhesives, Sealants and Elastomers - CASE.[2] It is particularly useful in epoxy flooring.[3] It may also be reacted with diethyl maleate utilizing the Michael reaction to produce a polyaspartic compound of CAS number 481040-92-0.[4] It may also be used in lubricants.[5] The product is also advertised as being useful as a chelating agent in a variety of applications including oil production.[6] It also is used in downfield oil and gas wells where there is an acidic stream to prevent corrosion to the bore piles.[7]
