Filed: 2003-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a combination production process for propylene oxide and a styrene monomer by a peroxide method in which the total yield of the styrene monomer is enhanced by recovering an effective component contained in a by-product oil which is a heavy residual material containing metal salts such as a sodium salt to convert into the styrene monomer without adding a complicated process or the like.  <P>SOLUTION: This combination production process for propylene oxide and a styrene monomer by the peroxide method has a process for separating a fraction containing metal salts from the raw material liquid of a dehydration process by means of distillation. The production process is characterized in that a styrene monomer precursor component having a phenylethoxy group as a basic skeleton is recovered from the fraction in the process for separating a high boiling point fraction containing the metal salts, and is fed to the dehydration process for producing the styrene monomer to be converted thereinto. The recovering method for the precursor component is preferably a distillation method.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
