abstract high-purity 2-mercaptobenzothiazole (2-mbt) is prepared from crude 2-mbt by aniline method under high pressure by solvent crystallization and deep impurity removal.
zn-catalyzed sustainable one-pot synthesis of rubber,a greatly improved process for simultaneously producing the widely applied rubber accelerator tetramethylthiuram monosulfide (tmtm) and lubricant additive triphenyl thiophosphate (tppt) from inexpensive and nontoxic feedstock tetramethylthiuram disulfide (tmtd) and triphenylphosphite (tppi) is herein reported. zinc oxide is used as an efficient and readily recyclable heterogeneous catalyst
purification of high-purity 2-mercaptobenzothiazole by two-steps
the highest purity of 2-mbt, above 99% was obtained using nitrobenzene, toluene and ethanol, even at a concentration of 2-mbt above 50 wt%.

purification of 2-mercaptobenzothiazole by solvent extraction
the highest purity of 2-mbt, above 99% was obtained using nitrobenzene, toluene and ethanol, even at a concentration of 2-mbt above 50 wt%. increasing temperature and decreasing concentration of the raw material have a positive influence on the purification process.
accelerator tdec high quality supplier,used for super accelerator in natural rubber, styrene-butadiene rubber. in general, using with some other kind of accelerators such as benzothiazole, sulfonamide. a fast velocity at vulcanizing temperature can be obtained, and intension can be increased.

- Is MBT carcinogenic to humans?
- The Working Group of Volume 115 of the IARC Monographs classified MBT as probably carcinogenic to humans (Group 2A) based on limited evidence of carcinogenicity in humans that it causes bladder cancer, and sufficient evidence of carcinogenicity in experimental animals. What evidence is this classification based on?
