Abstract
A process for the decomposition of cumene hydroperoxide to phenol, acetone, and alpha-methylstyrene is presented. In this process, cumene hydroperoxide and sulfuric acid are reacted in a reflux cooled reactor the products of which are transported under inhibited conditions to a plug flow reactor, and are reacted to produce phenol, acetone, and alpha-methylstyrene. In one embodiment of the invention, a heat exchanger is used to obtain and maintain the inhibited conditions of the transported reactor products.
