Acrylonitrile is produced by passing a gaseous mixture comprising propylene, molecular oxygen and ammonia upwardly through a fluidized bed comprising particles of a highly-active acrylonitrile catalyst in physical admixture with particles of a composite consisting essentially of antimony oxide and silica. The use of the antimony oxide-silica composite moderates the effect of the highly-active acrylonitrile catalyst reducing its activity sufficiently to enable the use of longer residence times, but without reducing the acrylonitrile selectivity of the catalyst.

Fluidized bed process for producing acrylonitrile and catalytic mixture

A process for producing aliphatic amines which comprises reacting an aliphatic alcohol or an aliphatic aldehyde with an aminating agent selected from the group consisting of ammonia, a primary amine and a secondary amine in the liquid phase in the presence of an unsupported catalyst consisting essentially of (1) copper oxide or copper hydroxide (2) nickel oxide or nickel hydroxide, and, optionally, (3) an oxide or an hydroxide of a Group II A metal.
