Verfahren zur Herstellung eines Nitrils

摘要

Nitriles are prepared by catalytic ammoxidation of an alkane by passing a feed gas contg. the alkane and ammonia in the vapour phase at an elevated temp. over a solid catalyst consisting of the oxides of vanadium and antimony, or a compd. contg. vanadium, antimony and oxygen. Used esp. for the prepn. of acrylonitrile or methacrylonitrile from propane or isobutane. The catalyst has a high reaction selectivity, and high yields of nitriles are obtained.
