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
nurchem mbt-80 accelerator rubber chemicals supplier,nurchem mbt-80 readily disperses in rubbers. it is very active at temperatures above 130-135° c. it can be used alone but low temperature curing can be achieved by the use of tmtd, tetd or dpg as secondary accelerators. typical values : melting point：174oc. density：1.50. purity：≥98%. ash (950℃)：≤0.5 %. heating loss：≤0.5 %.
quantitative analysis of the 2-mercaptobenzothiazole rubber accelerator
both the mbt and pe sample were solid powders. mbt powder with a purity of 97% was purchased from shuns hang chemical of china, and pe powder was provided by sigma-aldrich company. to reduce the interference of moisture, the sample was placed in a vacuum drying oven at 323 k for two hours firstly.

rubber accelerator 2-mercaptobenzothiazole (mbt)
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
2-mercaptobenzothiazole international agency for research,2-mercaptobenzothiazole (wick et al., 2010). a single method has been described for the deter-mination of 2-mercaptobenzothiazole in dietary products (barnes et al., 2003). 1.4 occurrence and exposure due to its use as an accelerant in rubber vulcanization, 2-mercaptobenzothiazole can be found as a contaminant in rubber products.
2-mercaptobenzothiazole determination of2 publisso,etection of the vulcanisation accelerator 2‐mercaptobenzothiazole (mbt) in urine. after adding a labelled internal standard (mbt‐d4), the samples. are enzymatically hydrolysed to release free mbt from the conjugated mbt compounds. after online purification and enrichment, the analyte is separated from accompany.
- What is the analytical standard for 2-mercaptobenzothiazole?
- The analytical standard 2-mercaptobenzothiazole (99 %) was obtained from Fluka, and the deuterated internal standard 2-mercaptobenzothiazole- (2,4,5,6-d 4) was custom synthesized at IDM (Teltow, Germany). The identification and purity of the deuterated internal standard were confirmed by 1 H-NMR and 13 C-NMR.
- 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.
