The embodiment of the application provides a kind of
propane ammoxidation preparation
acrylonitrile, it is related to
acrylonitrile generation technical field;The method comprises:
propane,
ammonia and
oxygen are mixed, and
mixed gas is obtained;The
mixed gas occurs
ammoxidation under the action of
metal oxide composite catalyst, and
acrylonitrile is obtained;The
metal oxide composite catalyst includes Mo-V
base metal oxide, and also includes
alkali metal or
alkaline earth metal.The method of the present application has relatively mild
reaction conditions, the yield can basically reach more than 60%, the selectivity can reach more than 80%, improves the
raw material utilization rate, reduces
energy consumption and equipment investment, thereby effectively reducing the production cost of acrylonitrile.At the same time, the process of the present application can effectively control the
side reaction in the reaction process, reduce the generation of by-products, and reduce the difficulty of subsequent separation and purification of reaction products.
