MANUFACTURING METHOD OF PHENOL, ACETONE, AND ALPHA-METHYLSTYRENE, CAPABLE OF INCREASING THE AMOUNT OF PRODUCED ALPHA-METHYLSTYRENE WITHOUT DECREASING THE AMOUNT OF PRODUCED PHENOL AND ACETONE

摘要

PURPOSE: A manufacturing method of phenol, acetone, and alpha-methylstyrene is provided to selectively increase alpha-methylstyrene by using a separation dehydration process of alpha-methylstyrene.;CONSTITUTION: A manufacturing method of phenol, acetone, and alpha-methylstyrene comprises a step of manufacturing a cumene hydroperoxide stream by oxidizing cumene; a step of separating a part of the cumene hydroperoxide stream and manufacturing a cumyl alcohol by hydrogenating the separated stream under the presence of a precious metal catalyst; a step of dehydrating the cumyl alcohol-containing reactant under the presence of an acidic catalyst; and a step of separately dehydrating the residual part of the cumene hydroperoxide stream.;COPYRIGHT KIPO 2013
