Title Sb-Re composite oxide catalyst ammoxidation
Abstract An object of the present invention is to provide an ammoxidation reaction catalyst composed of an Sb--Re compound oxide with which ammoxidation into an unsaturated nitrile such as methacrylonitrile or the like can be performed in the presence of a molecular oxygen-containing gas and ammonia, and a method for manufacturing an unsaturated nitrile such as methacrylonitrile or the like from an aliphatic hydrocarbon such as isobutylene, isobutane or the like using this ammoxidation reaction catalyst. An unsaturated nitrile such as methacrylonitrile or the like is manufactured by subjecting an aliphatic hydrocarbon such as isobutylene, isobutane or the like to vapor phase contact ammoxidation with ammonia and a molecular oxygen-containing gas in the presence of an ammoxidation reaction catalyst composed of an Sb--Re compound oxide such as SbRe2 O6 or the like.
