Processes of Altax Production

Abstract

Works on existing ways of producing Altax (2,2'-dibenzothiazolyl disulfide), an important accelerator of rubber vulcanization, are analyzed. It is shown that the main means of its production is the oxidation of 2-mercaptobenzothiazole (Captax) by different oxidizers (e.g., oxygen in the presence of catalysts, hydrogen peroxide) and electrochemical oxidation. Based on the analysis of the literature data, a small-scale Altax production technology is developed at the Boreskov Institute of Catalysis and tested at a pilot plant designed at the institute’s Volgograd Branch.
