FIELD: oxidation catalysts. SUBSTANCE: high-efficiency catalysts for oxidative purification of hydrocarbon distillates, diesel fuel, waste waters, and gas emissions from sulfur compounds are prepared on basis of polysubstituted cobalt phthalocyanine. For that, cobalt phthalocyanine is sulfurized with chlorosulfonic acid while simultaneously treating reaction mixture with hydroxylamine sulfate and potassium bromide. EFFECT: reduced expenses due to utilization of accessible and inexpensive starting materials, simplified preparation technology, and improved catalytic characteristics. 1 tbl, 3 ex
