Procedure

The conversion step is a step for obtaining cumene by subjecting cumyl alcohol obtained in the epoxidation step to hydrogenation-containing reaction and recycling the cumene to the oxidation step. As a method for converting cumyl alcohol into cumene, a method of first dehydrating cumyl alcohol to obtain α-methylstyrene and then hydrogenating α-methylstyrene to convert into cumene (dehydration-hydrogenation method), and a method of subjecting cumyl alcohol to hydrogenolysis to directly convert into cumene, can be illustrated.
