Process for producing monoalkenyl armomatic hydrocarbon compound

摘要

A process for producing a monoalkenyl aromatic hydrocarbon compound which comprises alkenylating a side chain of an aromatic hydrocarbon compound having at least one hydrogen atom bonded at an alpha -position of the side chain (such as xylene) with a conjugated diene having 4 or 5 carbon atoms (such as butadiene) in the presence of a catalyst comprising a mixture obtained by heat treating metallic sodium together with a mixture of an aluminum oxide and a potassium compound in an inert gas atmosphere. The process produces a commercially useful monoalkenyl aromatic hydrocarbon compounds in a high yields and at a low cost with enhanced safety.
