Abstract
Vapor phase ammoxidation reaction and vapor phase catalytic oxidation reaction of methylbenzenes and related derivatives were investigated. The compounds having acid anhydride or imide group showed low tendency to complete oxidation under oxidizing atmosphere. Also, the oxidizability of benzonitrile, isophthalonitrile and terepthalonitrile under oxidizing atmosphere was very low. o-Substituents were all found to be difficult to from o-phthalonitrile, but easy to give phthalimide. In general, the rate of f romation of aromatic nitrile (one pass yield) in the presence of oxygen was higher in the reaction of aldehyde with ammonia than in that of carboxyl group with ammonia. The mechanism of vapor phase ammoxidation of methylbenzenes was considered to be through the reaction of ammonia with benzaldehyde or tolualdehyde formed from oxidation of methyl group.Keywords
