Description and Uses
4,4'-Diaminodicyclohexyl methane is a sodium salt of a cyclic anhydride that is used as a specific treatment for removing dodecanedioic acid from fatty acids. The reaction solution is stable at pH 4-5 and has a viscosity of less than 1000 cps. It has good stability in the presence of amines and can be used in chromatographic science, including chromatography and gas-liquid chromatography. The UV absorption maxima for the acid complex are 195 nm and 240 nm.
4,4'-Diaminodicyclohexylmethane is used as epoxy curing agents. It is a versatile intermediate to produce leather, rubber products, plastics, dyes, and photo sensitive polymers. It is used in manufacturing diisocyanates and polyamides. It is also used as lubricant additive as and corrosion inhibitor.
