FIELD: oxidation catalysts.
SUBSTANCE: invention concerns preparation of heterogeneous phthalocyanine catalyst for use in liquid-phase oxidation of sulfur-containing compounds and provides a method, which involves preparing nonwoven polypropylene carrier by treating it with boiling alkaline solution of sodium peroxycarbonate, 3.2-4.6 g/L, at pH 9-10 followed by treatment cobalt phthalocyanine-disulfonate, 3.2-4.6 g/L, and final treatment, which consists in washing preliminarily treated carrier with sodium hydroxide solution in concentration 0.1-0.5 g/L.
EFFECT: increased catalytic activity up to 92% and simplified catalyst preparation procedure.
