1. introduction. the compound 2-mercaptobenzothiazole (mbt), which has the iupac name 1,3-benzothiazole-2-thiol, was used as an accelerator in rubber factories [1, 2].in earlier periods, mbt was used as an assistant reagent on silica gel to detect the concentration of copper, lead, cadmium, and zinc in freshwater [3, 4], and to detect the concentration of mercury in seawater [5].
rubber accelerator dtdm characteristics, applications,dtdm (dithiodimorpholine) is a widely used rubber accelerator that plays a crucial role in the production of rubber products. this article aims to provide an overview of dtdm, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is dtdm? dtdm is an organic compound belonging to
mercaptobenzothiazoles: a new class of matrices for laser
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 advantage of higher tolerance to sample contaminants such as ionic detergents. 5-chloro-2-mercaptobenzothiazole (cmbt), an analog of mbt, has been found not only effective for the analysis
2-mercaptobenzothiazole determination of2,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 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 does MBT stand for?
- Anyone you share the following link with will be able to read this content: Provided by the Springer Nature SharedIt content-sharing initiative 2-Mercaptobenzothiazole (MBT) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires.
- 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.
- How much MBT is found in a urine sample?
- MBT was found in only one urine sample from the unexposed humans, at a value of 10.8 μg MBT per liter, whereas it was found in all samples from the tested workers at values of up to 6210 μg MBT per liter. 2-Mercaptobenzothiazole (MBT, benzothiazole-2-thiol, CAS 149-30-4) was introduced to rubber production in the late 1940s [ 1 ].
