抄録

In order to clarify the profile of vapour phase catalytic ammoxidation reaction with SO2 as an oxidizing agent, the reactions of various substituted aromatic compounds i.e. methylnaphthalene, ethylbenzene, cumene, styrene, benzaldehyde, n-heptane and methylcyclohexane were investigated.<br>It was found that the reaction of methylnaphthalene gave the corresponding naphthonitrile, while the reaction of ethylbenzene and cumene gave benzonitrile and styrene, benzonitrile, α-methylstyrene and a small quantity of α-phenylacrylonitrile, respectively. The reaction of methylcyclohexane gave benzonitrile and toluene. Also n-heptane was converted to benzonitrile and toluene more slowly than methylcyclohexane. Benzaldehyde was readily converted to benzonitrile even over fused alumina (Alundum: α-Al2O3) alone. The reactivity of these compounds decreased with increasing size of substituent group.<br>Addition of K2CO3 to catalyst supressed the activity for formation of nitrile, but little for dehydrogenation reaction. The dehydrogenation reactions were promoted even by the fused alumina catalyst (Alundum: α-Al2O3) alone.<br>Therefore, it was assumed that the dehydrogenation took place prior to formation of nitrile under the conditions of ammoxidation reaction.
