Abstract: Methacrylonitrile is manufactured by contacting a mixture of isobutylene, ammonia and oxygen at a temperature of 550-1,100 DEG F. with a catalyst composition corresponding to the formula SbaFebOc, in which a is a number from 1 to 99, b is a number from 50 to 1 and c is a number which satisfies the average valencies of antimony and iron in the oxidation states in which they exist in the catalyst. In the mixture of isobutylene, ammonia and oxygen used, the molar ratio of ammonia to isobutylene is from 0.05:1 to 5:1 and the molar ratio of oxygen to isobutylene is from 0.5:1 to 4:1. If desired the catalyst may be supported on conventional supports and may be activated before use by heating. Saturated hydrocarbons, water and diluents such as nitrogen and oxides of carbon may be present in the reaction mixture. Specifications 867,438 and 876,446 are referred to.
