1,6-hexanediamine is an important chemical product which is widely applied in many fields, (1) polyamides, such as nylon 66, nylon 610; (2) diisocyanate; (3) the curing agents and organic crosslinking agent of such as urea-formaldehyde resin, epoxy resin, etc. Hexanediamine products are highly monopolized by Invida, Basf and Oshende, which account for 74% of global production capacity. Adiponitrile hydrogenation is main technology for the synthesis of 1,6-hexanediamine., the application of hexamethylene diamine is expanded rapidly which results in a shortage of supply and demand with the continuous development of China's automobile industry

A new process is developed by the researchers of our company, which is used adipic acid as raw material, synthesized 1,6-hexanediamine through amidation-hydrogenation reaction, achieved high yield of 1,6-hexanediamine to meet the requirements of industrialization.
