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

- What is 2-Mercaptobenzothiazole (MBT) vulcanization accelerator?
- 2-Mercaptobenzothiazole (MBT) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. Given its wide use in household articles and industrial rubber products it has a high potential to migrate into the environment. Humans can be exposed by dermal, oral, or inhalative routes.
- What is the difference between MBT (m) and TMTD accelerator?
- ZMBT Accelerator: The combination of MBT (M) with ZMBT enhances the overall acceleration rate and provides better heat resistance and aging properties. 3. TMTD Accelerator: MBT (M) can be combined with TMTD to improve the processing safety and promote faster curing in rubber production.
- How do you make 2 mercaptobenzothiazole?
- 2-Mercaptobenzothiazole (MBT) is prepared by heating aniline, carbon disulfide, and sulfur in an autoclave at elevated temperature and pressure. Tars from the reaction can be removed by taking the crude MBT up in water by making the sodium salt, clarifying the solution, and then precipitating pure MBT with acid. Ohm RF; Rubber Chemicals.
- What is the maximum acceptable toxicant concentration (MATC) of 2 mercaptobenzothiazole (MBT)?
- The mean weight at the 380 ug/L level was 1.1582 g which was significantly reduced as compared to controls. The Maximum Acceptable Toxicant Concentration (MATC) was estimated to be greater than 41 ug/L and less than 78 ug/L.
