1,2-Diaminocyclohexane

1,2-Diaminocyclohexane is an organic compound with the formula (CH2)4(CHNH2)2. Described by the registry number CAS Registry number (RN) 694-83-7, it is a mixture of the two diastereoisomers, trans-1,2-diaminocyclohexane (RN 1121-22-8) and cis-1,2-diaminocyclohexane (RN 1436-59-5). The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH.

Manufacture

The product is available commercially as FlexaTram-DAM-950 and Dytek DCH-99. It is manufactured by the hydrogenation of o-phenylenediamine[1].

Uses

The product is an epoxy curing agent for use in Coatings, Adhesives, Sealants and Elastomers - CASE.[2] It may also be reacted with diethyl maleate utilizing the Michael reaction to produce a polyaspartic compound of CAS number 481040-92-0.[3] It may also be used in lubricants[4]. The product is also advertised as being useful as a chelating agent in a variety of applications including oil production.[5]. It also is used in downfield oil and gas wells where there is an acidic stream to prevent corrosion to the bore piles.[6]
