ABSTRACT:
A method of preparing acrylonitrile, which comprises reacting acetonitrile with methane at a temperature ranging from 650.degree. to 1,000.degree. C at a space velocity of 1,000 to 23,000 hr.sup.-.sup.1 in the presence of oxygen or a mixture thereof with an inert gas and a catalyst such as calcium bromide, potassium chloride, potassium bromide, bismuth oxide, molybdenum oxide or a mixture of bismuth oxide and molybdenum oxide.
The method according to the present invention makes it possible to increase the selectivity and the conversion of the process thus increasing its efficiency by 1.5-2 times.
