Process of catalytic synthesis of acetonitrile from acetic acid and ammonia at ?-Al2O3

Abstract

In the reaction of catalytic synthesis of acetonitrile from acetic acid and ammonia the influence of ratio of reagents, reactor temperature, addition of acetic acid, acetic anhydrite and acetamide into the reaction mixture of ethyl ether as well as catalyst promotion (?-Al2O3) by phosphoric acid on the parameters of the process. Optimal conditions of the reaction are determined and the scheme of commercial prototype process is suggested.
