ABSTRACT:
A method and catalyst for preparing styrene which comprises dehydrodimerization of toluene, followed by conversion of the resulting dehydrodimerization products to styrene. The conversion is conducted in the presence of ethylene using a catalyst consisting of chromium oxide, tungsten oxide and an alkali metal oxide supported by a carrier. The method according to the present invention makes it possible to increase the yield of styrene and simplify the process technology.
