CATALYST FOR OXIDATION OF SULFIDES Russian patent published in 1998 - IPC

FIELD: production of heterogeneous catalysts for liquid-phase oxidation of sulfides, applicable in gas, petroleum- extracting, petroleum-refining, petrochemical, wood- pulp and paper and other branches of industry. SUBSTANCE: catalyst contains cobalt phthalocyanine and water-insoluble derivatives, titanium dioxide, polyethylene and/or polyperfluoro-propylene as a carrying agent at the following relation of components, mass percent: cobalt phthalocyanine and/or water-insoluble derivative - 0.05 to 20; titanium dioxide - 0.05 to 20; polyethylene and/or polyperfluoro-propylene - the rest. Catalyst contains cobalt tetrachlorophthalocyanine, tetrachloromethylphthalocyanine or tetratrebutylphthalocyanine as a water-insoluble derivative of cobalt phthalocyanine. EFFECT: enhanced catalytic activity in reactions of oxidation of sulfide and mercaptide sulfur and enhanced mechanical strength. 3 tbl
