Vapor-phase amination of cyclohexanol with ammonia over silica-supported platinum and other platinum group metal (Ru, Rh, Pd, Ir) catalysts has been studied. Cyclohexylamine and aniline are the main products. Platinum is the most active metal, although there is not much difference in the activity between platinum and other metals. The reaction is suggested to proceed as follows. The first step, which is rate-determining, is the dehydrogenation of cyclohexanol to cyclohexanone intermediate, from which cyclohexylamine and aniline are formed in the parallel process via cyclohexylideneamine. From reaction-rate measurements on Pt/SiO<SUB>2</SUB> catalysts with different Pt particle size, the amination reaction has been found to be structure-insensitive. The catalytic activity decreases with time on stream probably because of the deposit of carbonacious or polymeric materials on the catalyst surface.
