Known laboratory-scale and industrial methods are reviewed therein concerning the production of one of the most important vulcanization accelerators such as kaptax (2-mercaptobenzothiazol) those are based on modifying the substituents in the thiazol ring and synthesizing from acyclic precursors. The latter include also the main industrial method of obtaining kaptax based on the reaction between aniline, sulphur and carbon disulphide dangerous from the environmental point of view. Potentialities are demonstrated concerning the development of methods for producing kaptax without using carbon disulphide, which would significantly improve the environment safety of the process
