Abstract
A method of producing unsaturated nitriles by reaction of an unsaturated hydrocarbon with ammonia and oxygen in a reactor having a fluidized catalyst bed comprising a regeneration zone and a reaction zone, characterized by introducing between about 3 percent and about 90 percent of the total amount of ammonia supplied to the reaction to the regeneration zone together with oxygen and introducing the remainder of the ammonia to the reaction zone together with the hydrocarbon feed.
