PURPOSE: A manufacturing method of a phenol, acetone, and alpha-methylstyrene is provided to selectively increase alpha-methylstyrene which is considered as a by-product in a phenol manufacturing process, by a hydration process of cumyl alcohol. CONSTITUTION: A manufacturing method of a phenol, acetone, and alpha-methylstyrene comprises: a step of manufacturing cumene hydroperoxide stream by oxidizing cumene; a step of separating at least a part of the cumene hydroperoxide stream, and manufacturing a cumyl alcohol by hydrogenation under the presence of a Pd-Co catalyst; a step of dehydrating the cumyl alcohol-containing reactant under the presence of a resin catalyst; and a step of dehydrating residual parts of the cumene hydroperoxide stream which did not pass through the hydrogenation.
