ABSTRACT:
A process is provided for the conversion of lactams to the corresponding aminonitriles and alkenenitriles comprising contacting the lactam with ammonia in the presence of a catalyst in a first reaction zone to form the corresponding aminonitrile and a byproduct polymeric material, and contacting the byproduct in the presence of gamma-alumina, a second catalyst, in a second reaction zone to form the corresponding isomeric alkenenitriles. The aminonitrile and the alkenenitriles are both recovered as products of the process.
