"PROCESSES FOR INCREASING THE PRODUCTION OF HCN AND ACETONITRILLA BY-PRODUCTS PRODUCED DURING THE MANUFACTURE OF ACRYLONITRILLA, AND FOR THE AMOXIDATION OF A C ~ 1 ~ C ~ 4 ~ KETONE MIXTURE AND A CRUDE KETONE TO PRODUCE HCN. Process to increase the production of both HCN and acetonitrile, which are produced during the manufacture of acrylonitrile, comprising introducing a hydrocarbon, selected from the group consisting of propylene and propane, a crude ketone and / or a mixture of at least two ketones, ammonia and air, in a reaction zone containing a catalyst for amoxidation, react the hydrocarbon, ketone, ammonia and oxygen on said catalyst at an elevated temperature to produce acrylonitrile, hydrogen cyanide and acetonitrile and, recover from the reactor a acrylonitrile, hydrogen cyanide and acetonitrile.
