Method for separating p-cresol

摘要

PROBLEM TO BE SOLVED: To provide a method for the separation and concentration of a mixed cresol, especially an isomer mixture of m-cresol and p-cresol by using a separation membrane composed of a zeolite membrane.;SOLUTION: The method for separating p-cresol comprises supplying the mixed cresol containing p-cresol in gas phase to a material supply side of the separation membrane composed of zeolite, and recovering p-cresol at the permeating and recovering side of the separation membrane.;COPYRIGHT: (C)2007,JPO&INPIT
