FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing dibenzthiazolyl disulfide by oxidation of alkaline solution of 2- mercaptobenzthiazole with oxygen in the presence of cobalt phthalocyanine as a catalyst at 50 C. Process is carried out in 3-10-fold excess of 2-mercaptobenzthiazole by solubility in weakly alkaline medium where concentration of alkaline metal hydroxide is 0.35-1.0 weight % in the presence of cobalt disulfophthalocyanine as a catalyst taken in amount (3-5) x 10-4 mole per 1 mole of 2-mercaptobenzthiazole. EFFECT: simplified method for preparing. 4 ex
