CATALYTIC PROCESS: AMMOXIDATIONS OF HYDROCARBONS, AMMOXIDATION OF ALKANES (E.G., PROPANE AND ISOBUTANE) INTO UNSATURATED NITRILES (E.G. ACRYLONITRILE AND METHACRYLO-NITRILE RESPECTIVELY) BY USING ANTIMONY OXIDE CONTAINING CATALYST AND A CHLORO-ALKANE IN THE FEED GASES.

摘要

I Claim : (1) A process for the catalytic ammoxidation of acyclic alkanes to unsatutated aliphatic nitriles comprising contacting a gaseous mixture of the hydrocarbon (acyclic alkane), ammonia and oxygen with a solid catalyst consisting of oxides of antimony alone or in combination with the oxides of other metals and metalloids, the said catalyst being maintained in the presence of a halogen at its surface and at a temperature of 300C to 700C.
