US8669389B2 Blocked mercaptosilane coupling agents
The temperature of the reaction mixture increased to a maximum value of 130° C. The reaction mixture was cooled to room temperature and 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxylbenzyl)benzene (3 grams, 0.004 mole) was added.
k is 1 to 2; m=1 to 5; n=1 to 5; r is 2 to 4; z is 0 to 2; with the proviso that if A is phosphorus, then k is 2. In another embodiment, the present invention is directed to a process for the preparation of the blocked mercaptosilane comprising reacting a thioacid with a silylated hydrocarbon containing r terminal carbon-carbon double bonds.

- What is dibenzothiazol 2 yl disulfide?
- Research Triangle Park, North Carolina. Dibenzothiazol-2-yl disulfide is an organic disulfide resulting from the formal oxidative coupling of the thiol groups of two molecules of 1,3-benzothiazole-2-thiol. It is used as an accelerator in the rubber industry. It has a role as an allergen. It is an organic disulfide and a member of benzothiazoles.
- What is the physiologic effect of 2'-dithiobisbenzothiazole?
- The physiologic effect of 2,2'-dithiobisbenzothiazole is by means of Increased Histamine Release, and Cell-mediated Immunity. To determine the metabolic disposition of (l4)C-2-mercaptobenzothiazole (MBT) and (14)C-2-mercaptobenzothiazole disulfide (MBTS) male and female rats were dosed topically.
- What is 2 2 dithiobisbenzothiazole used for?
- It is a Standardized Chemical Allergen. The physiologic effect of 2,2'-dithiobisbenzothiazole is by means of Increased Histamine Release, and Cell-mediated Immunity 2. Its industry uses also include fillers, fuels and fuel additives, intermediates, process regulator, propels and blowing agents 2.
- How stable are mercaptobenzothiazoles?
- The stability of the mercaptobenzothiazoles constituting the mercapto mix was studied both in petrolatum and in buffer solution at pH 6.5 with and without glutathione. In petrolatum vehicle, dibenzothiazyl disulfide was the dominant compound found in stored mercapto mix.
- Is mercaptobenzothiazole an occupation-related illness?
- The examination first indicated only a positive reaction to 2-mercaptobenzothiazole, patch to the miner's suit, rubber gloves, rubber boots and the cable being negative, which followed to a decision that the illness was not occupation-related.
- Is dibenzthiazyl disulfide teratogenic?
- The teratogenic potential of dibenzthiazyl disulfide (MBTS) was studied in Wistar rats. Pregnant rats were given MBTS at a dosage of 0, 0.04, 0.2 or 1% in the diet from day 0 to day 20 of pregnancy. Daily intakes of MBTS were 26 mg/kg for the 0.04% group 127 mg/kg for the 0.2% group and 596 mg/kg for the 1% group.
