WebAdiponitrile is an important starting material in nylon production which is obtained by double hydrocyanation of 1,3-butadiene. In a first hydrocyanation, 1,3-butadiene is hydrocyanated to 3-pentenenitrile, and the by-products obtained are mainly 2-methyl-3-butenenitrile, 2-pentenenitrile, Cg nitriles and methylglutaronitrile. Webadiponitrile: [noun] the high-boiling liquid dinitrile NC(CH2)4CN of adipic acid made from 1,4-dichlorobutane and sodium cyanide and used to make the nylon intermediate …
