Abstract: A process is disclosed for producing ?-methylstyrene, acetone, and phenol wherein the amount of ?-methylstyrene produced may be controlled by selectively converting a portion of the cumene hydroperoxide to dimethyl phenyl carbinol, the hydrated form of ?-methylstyrene. The dimethyl phenyl carbinol thus produced will lead to increased production of ?-methylstyrene upon dehydration in the acid cleavage unit of the phenol plant. By controlling the fraction of the cumene hydroperoxide reduced to dimethyl phenyl carbinol, the amount of ?-methylstyrene produced in the plant can be continuously set to meet the demand of the market for ?-methylstyrene. Also disclosed is a non-acidic catalyst for reduction of cumene hydroperoxide.
