    • PURPOSE: A manufacturing method of an alpha-methyl styrene is provided to selectively increase an alpha-methyl styrene in a phenol plant by converting a cumene hydroperoxide into a cumyl alcohol with high selectivity by a hydrogenation process. CONSTITUTION: A manufacturing method of an alpha-methyl styrene comprises a step of manufacturing a cumene hydroperoxide stream; a step of separating a part of the cumene hydroperoxide stream and selectively hydrogenating the cumene hydroperoxide to manufacture a cumyl alcohol; and a step of condensing the cumyl alcohol-containing reactant and manufacturing a methyl styrene-containing product by dehydrating the result under the presence of an acid catalyst. The hydrogenation is conducted by supplying hydrogen gas to the cumene hydroperoxide. [Reference numerals] (AA) Cumene; (BB) Phenol, AMS, acetone
