Processes for synthesis of altax

Literature analysis was focused on the existing processes for synthesis of altax (2,2’-dibenzothiazolyldisulfide) as an important rubber vulcanization accelerator. Oxidation of mercaptobenzothiazole (captax) with various oxidants such as oxygen in the presence of catalysts, hydrogen peroxide etc., as well as electrochemical oxidation was shown to be the primary way to altax. The data from literature were the basis to develop a low-tonnage technology for synthesis of altax; the technology was developed at the Boreskov Institute of Catalysis and tested using a pilot setup at the Volgograd Department of BIC.
