Method of preparing acrylonitrile

摘要

A method of preparing acrylonitrile, which comprises reacting acetonitrile with methane at a temperature ranging from 650 DEG to 1,000 DEG C at a space velocity of 1,000 to 23,000 hr<->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.
