Adiponitrile (CAS 111-69-3) is Key Intermediate for Synthetic Fiber Production
26 Apr 2012 • by Natalie Aster
Adiponitrile (1,4-dicyanobutane or adipyldinitrile) is an organic compound with the chemical formula (CH2)4(CN)2 and a melting point between 1-3°C. This dinitrile is a viscous, colourless liquid, which is soluble in alcohol and chloroform.
Early industrial routes for adiponitrile synthesis involved furfural to later move to the chlorination of butadiene to give 1,4-dichloro-2-butene, which, with sodium cyanide, converts to 3-hexenedinitrile, which in turn can be hydrogenated to adiponitrile. Adiponitrile was also produced from adipic acid, by dehydration of the diamide, but the route was abandoned following the closure of China’s last small plant.
Today, the majority of adiponitrile is prepared by the nickel-catalyzed hydrocyanation of butadiene. The method, regarded as the most cost-effective process, was pioneered by DuPont. However, this route is sensitive to natural gas prices. The other major industrial route involves electrosynthesis, which starts from the electrohydrodimerization of acrylonitrile.
The only application for adiponitrile is as an intermediate for hexamethylenediamine production. In 2010 1197ktes of adiponitrile were synthesized, 71% of which was produced by the butadiene/gas route and 29% from propylene, via acrylonitrile. In line with overall hexamethylenediamine growth, global demand for adiponitrile is rising at a CAGR of 1.4%, from 2000 to 2020.
