ABSTRACT:
A method for preparing an unsaturated compound mainly comprising monoolefins, or a mixture of .alpha., .beta.-unsaturated nitriles and monoolefins comprises coming a mixed gas which comprises paraffins and oxygen, or paraffins, oxygen and ammonia in contact with a catalyst which comprises (1) an oxide of phosphorus and (2) at least one oxide selected from the group consisting of indium oxide and tin oxide or comprises, in addition to the foregoing catalytic components, (3) at least one oxide selected from the group consisting of vanadium oxide, tungsten oxide and molybdenum oxide. The method makes it possible to prepare monoolefins, or a mixture of .alpha., .beta.-unsaturated nitriles and monoolefins in high yield and high selectivity from cheap starting materials, parafins.
