my country’s demand for adiponitrile relies on imports. There is huge room for development of the butadiene cyanide hydrogenation to adiponitrile process.

There are three main preparation methods for adiponitrile: adipic acid amination, acrylonitrile electrolysis, and butadiene cyanide hydrogenation. Among them, the hydrogenation of butadiene cyanide to adiponitrile has the advantages of easy availability of raw materials, low energy consumption, low cost, short process flow, large-scale production, high yield, high product quality, and low environmental pollution. It…
