Abstract：2-Mercapotobenzothiazole (MBT) is an important vulcanization accelerator that is widely used in the rubber industry. The solvent-based methods for the preparation of high-purity MBT need to use a suitable crystallization solvent.
In a process for the preparation of 2-mercaptobenzothiazole from aniline, sulfur and carbon disulfide under pressure and for separation of the 2-mercaptobenzothiazole from the crude reaction product by cooling and recycling the desirable intermediates and by-products into the reactor together with aniline, sulfur and carbon disulfide, the reaction is carried out using a
