METHOD FOR PRODUCING ACETONITRILE

摘要

A method for producing acetonitrile by performing a gas-phase reaction step for obtaining water-containing crude acetonitrile by subjecting acetic acid and ammonia to a gas-phase reaction while in the presence of a catalyst containing a solid acid catalyst, and a refining step for obtaining an acetonitrile product by refining the water-containing crude acetonitrile, wherein the water content in the water-containing crude acetonitrile is 47 mass% or more relative to 100 mass% of the water-containing crude acetonitrile, and the toluene content therein is 1 mass ppm or higher relative to 100 mass% of the acetonitrile.
