CATALYST AND PROCESS FOR PRODUCING AROMATIC NITRILES

摘要

The present invention relates to a catalyst which comprises a vanadium oxide, a chromium oxide, a molybdenum oxide and a boron oxide supported on a silica carrier. This catalyst is suitable for use in the production of aromatic nitriles from alkyl-substituted aromatic compound by the catalytic reaction of a gas mixture containing an alkyl-substituted aromatic compound, ammonia and oxygen or a gas containing molecular oxygen over a catalyst. The present invention further relates to a process for producing the aromatic nitriles using said catalyst.
