what is 2-mercaptobenzothiazole? 2-mercaptobenzothiazole (mbt) is an industrial chemical that is used principally in the manufacture of rubber. what were the results of the iarc monographs evaluation of mbt? the working group of volume 115 of the iarc monographs classified mbt as probably carcinogenic to humans (group 2a) based on limited
rubber auxiliary agent zbec accelerator for rubber supplier,zbec accelerator zinc dibenzyldithiocarbamate cas 14726-36-4. zbec is a dithiocarbamate accelerator for rubber compounds. it is typically used to replace more conventional dithiocarbamates in compounds to reduce or eliminate the generation of potentially hazardous nitrosamines during the vulcanization process.
2 mercaptobenzothiazole an overview sciencedirect topics
2-mercaptobenzothiazole (2-mbt) is mainly used as a vulcanisation accelerator in the production of rubber. other applications are as a fungicide in paints and varnishes as well as for the external treatment of animals. because of its manifold applications in consumer products, for example in soothers, exposure of the general population to 2-mbt
Accelerators for tires and rubber products,an accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency.

in literature (manninen et al., 1996) an acidic hydrolization at room temperature with 2-mercaptobenzoxazol (mbo) as internal standard was described. with the help of urine samples of persons exposed to 2-mbt, the recoveries of different hydrolysis conditions were tested. it turned out that enzymatic hydrolysis yielded up to fourfold higher 2
tibtm, diisobutyl thiuram monosulfide cas no.-00-1,tibtm is a rubber vulcanization accelerator, a substitute for tmtm, and does not produce carcinogenic nitrosamines. tibtm is a multifunctional accelerator with both the auxiliary accelerator function of sulfenamide accelerator and the performance of anti-scorching agent.

plant assimilation kinetics and metabolism of 2
2-mercaptobenzothiazole (mbt) is a tire rubber vulcanizer found in potential sources of reclaimed water where it may come in contact with vegetation. in this work, we quantified the plant assimilation kinetics of mbt using arabidopsis under hydroponic conditions. mbt depletion kinetics in the hydroponic medium with plants were second order (t1/2 = 0.52 to 2.4 h) and significantly greater than
mercaptobenzothiazoles: a new class of matrices for laser,we report 2-mercaptobenzothiazole (mbt) and its analogs as a class of new matrices for matrix-assisted laser desorption mass spectrometry (maldi-ms) at 337 nm. mbt has been used successfully for the desorption of proteins up to 100,000 u. a comparison with sinapinic acid and α-cyano-4-hydroxycinnamic acid indicates that mbt provides the same level of sensitivity and resolution, but offers the
mercaptobenzothiazole rubber accelerator,mercaptobenzothiazole. except where otherwise noted, data are given for materials in their standard state (at 25 °c [77 °f], 100 kpa). 2-mercaptobenzothiazole is an organosulfur compound with the formula c6h4(nh)sc=s. a white solid, it is used in the sulfur vulcanization of rubber.

- What is mercaptobenzothiazole used for?
- ... 2-Mercaptobenzothiazole (2-MBT) is used in the rubber industry as a non-volatile vulcanisation accelerator in the preparation of antioxidants, dyes, polymers, photographic materials and as an excellent inhibitor in metal protection [1,2]. Recently, 2-MBT has been employed as a main component of the modified Julia olefination reaction [3, 4].
- Can mercaptobenzothiazole be used to vulcanize rubber?
- To read the full-text of this research, you can request a copy directly from the authors. 2-Mercaptobenzothiazole has found widespread industrial applications for the vulcanisation of rubber and, more recently, as a key component of the modified Julia olefination reaction.
- Who is exposed to MBT?
- In the studies evaluated by the IARC Monographs Working Group, exposure to high amounts of MBT in humans occurred in workers in the chemical industry, but workers in the rubber or tyre-manufacturing industries may also be exposed to MBT.
- 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?
