Mercaptobenzothiazole, MBT Chemical

Properties:

2-Mercaptobenzothiazole (MBT) is an organosulfur compound with the formula C6H4NSCSH. The molecule consists of a benzene ring fused to a 2-Mercaptothiazole ring. MBT chemical is used in the vulcanization of rubber.

Using mercaptobenzothiazole, rubber vulcanizes with less sulfur and at milder temperatures. Both factors give a stronger product. This effect was reported in 1921 by workers at Pirelli and at Goodyear Tire & Rubber.

Mercaptobenzothiazole is used as a cooling tower biocide. MBT chemical has also been used in the past in the gold-mining industry to “float” the gold from ore residue as part of the extraction process.
