MBT Structural Formula


2-Mercaptobenzothiazole (MBT) is an organosulfur compound with the formula C6H4NSCSH. The molecule consists of a benzene ring fused to a 2-Mercaptothiazole ring.2-Mercaptobenzothiazole (MBT) is used in the vulcanization of rubber.Using MBT, 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.
MBT is used as cooling tower biocide.[citation needed] 2-Mercaptobenzothiazole (MBT) 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
