Investigations on electrochemical oxidation of 2-mercaptobenzothiazole

237-242The electrochemical oxidation of 2-mercaptobenzothiazole (2-MBT) at pyrolytic graphite electrode has been studied in phosphate buffers of pH range 2.31-10.3. It is observed that oxidation of 2-MBT does not stop at disulphide stage but further oxidation followed by desulphurization gives elemental sulphur and mono sulphide as the final products of oxidation. A tentative mechanism for formation of products has been proposed
