Abstract
A new metal phthalocyanine catalyst is prepared by reacting a 4-sulfophthalic compound, a metal salt, an ammonium donor compound and water at reaction conditions which include heating to 255.degree. to 325.degree. C at a pressure of 1 to 100 atmospheres for 1/2 to 10 hours. The catalyst is used to oxidize mercaptans.
