2-Mercaptobenzothiazole;2-Benzothiazolethiol;MBT;Captax;Dermacid;Mertax;Thiotax;2-Mercapto benzothiazole
Molecular formula : C7H5NS2
MW : 167.25
CAS No. :149-30-4

nature : ginger monoclinic needle-like leaves or crystallization. Melting point 180.2-181.7 ° C and relative density of 1.42. At 25 ° C the solubility (g/100ml) : ethanol 2.0, 1.0 ether, acetone 10.0, 1.0 benzene, carbon tetrachloride < 0.2. Glacial acetic acid was dissolved, and the alkali - soluble carbonate alkali solution, do not dissolve in water. A bitter, not the odor.

Preparation : Many of the goods production methods, but the main difference is in aniline, o-nitrochlorobenzene and diphenylthiourea raw materials for the three different methods. 1. Aniline is usually aniline, carbon dioxide and sulfur in Autoclave direct response, but also can be used aliphatic amines, dimethyl formamide, three THIAZOLI and obtain more formaldehyde, replacing carbon disulfide, sulfur and aniline under the pressure of reaction. Aniline raw materials used for the method, the reaction pressure is high, generally excludes more, as high as aging, also called hypertension law. 2. To nitrochlorobenzene for raw materials and ortho-nitrochlorobenzene reductant sulfur sodium hydride, sodium sulfide or hydrogen sulfide over reaction can be reduced to o-aminothiophenol. Further reaction with carbon disulfide in the system for M. Some of these methods a longer reaction time (sodium sulfur about 20h), but can lower the atmospheric pressure or under pressure, also known as the Atmospheric law. 3. To diphenylthiourea raw materials for this method reaction pressure between the two methods mentioned above, excludes the following, the general said the MV Act.

purposes : the goods as general-vulcanization accelerator, for a wide variety of rubber. For natural rubber and sulfur vulcanization usually to the rapid syntheic facilitating role. But the use of Progressive need zinc oxide, such as fatty acid activation. Often with other accelerator system used, such as two Thio autumn Lamb and Et2NH2DDC tellurium and will be used for the promotion of butyl rubber agent; With three base butadiene dilute acid with lead and can be used in light-colored water resistance of chlorosulfonated polyethylene rubber compound. Often in latex with two DITHIOCARBAMATES and use, and with two ethyl Et2NH2DDC two used ethylamine, may RTV. The goods in the rubber easily dispersed, and less pollution. But because its bitterness, it is not appropriate for food contact with the rubber. M is the catalyst for promoting agent MZ, DM, NS, DIBS, CA, DZ, accelerator, the MDB intermediates, 2-mercapto - MBT and 1-amino-4-nitro - anthraquinone and potassium carbonate in two DMF 3h return can be obtained scattered red dye S-GL (C. I. Disperse Red 121). Such dyes for polyester and blended fabric dyeing. 2-mercapto - MBT for electroplating additive known as acid copper plating brightener M, in a copper sulfate salt mainly serve as a bright copper plating shop help brightener. In addition, the system is also used materials from pesticides fungicides, fertilizer synergist, cut Consumers oil and lubrication additives, photographic chemicals and the organic anti-ash agents, such as metal corrosion inhibitor. In addition, it is the chemical analysis of reagent. The goods low toxicity to the skin and mucous membranes have a stimulating effect.
