フェノール、アセトン、α-メチルスチレン及び酸化プロピレンのコプロダクション及びその触媒

Japanese Patent JP2006509829

A

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