Abstract

PURPOSE: To reduce the formation of methyl acetate as a by-product and to decrease the orginal unit of acetic acid by recivering methyl acetate from the reaction mixture by distillation and returning it to the oxidation reactor in SD method of preparing terephthalic from p-xylene by oxidation.
