Uses and applications

What the substance is used for, by industry and function

Intermediate in the manufacture of nylon, organic synthesis.

Preparation of adipoquanamine, extractant for aromatic hydrocarbons.

Industrial uses: Other, Intermediate.

How it is made

Chlorination of butadiene to dichlorobutylene, which is reacted with 35% sodium cyanide soln to yield 1,4-dicyanobutylene, which is hydrogenated to adiponitrile. Also by electroorganic synthesis from acrylonitrile.

Reaction of adipic acid with ammonia (either liquid or vapor phase) produces adipamide as intermediate, which is subsequently dehydrated to adiponitrile.

Prepared by dimerization of acrylonitrile at the cathode of an electrolytic cell (propionitrile and bis(cyanoethyl) ether are by-products).
