Procedure

2-Mercaptobenzothiazole can be produced from aniline by the following synthesis approach. Here, carbon disulfide can be generated and separated for example by reacting mustard oil, which is contained about 0.4% in leaf mustard, with hydrogen sulfide. The method allows to produce the vulcanization accelerator without petroleum resources. Dibenzothiazyl disulfide is synthesized by oxidizing thus produced 2-mercaptobenzothiazole.
