Basic Info

What is 2-Mercaptobenzothiazole?

2-Mercaptobenzothiazole is a light yellow powder or granules with an unpleasant odor. The melting point is above 173.0°C; the relative density is 1.41~1.48; it is hardly soluble in water and n-hexane, easily soluble in acetone, soluble in ethanol, and slightly soluble in benzene. 2-Mercaptobenzothiazole is acidic, has strong vulcanization acceleration, relatively flat vulcanization curve, and is less polluting.

2-Mercaptobenzothiazole (likewise known as accelerator M or accelerator MBT, also called quick heating powder) is a general-purpose vulcanization accelerator for rubber. It has the attributes of rapid vulcanization velocity, low vulcanization flatness, as w ell as no very early vulcanization throughout mixing, and is also widely utilized in the rubber processing sector.

The artificial technique of accelerator M has several, can be divided right into o-nitrochlorobenzene method, aniline method, nitrogen as well as aniline blended technique, nitrogen approach, nitrosobenzene approach and so on according to the raw mater ial taken on, generally takes on one Of the most typical techniques are o-nitrobenzene approach, aniline technique, nitrogen and also aniline combined approach. Nevertheless, the o-nitrochlorobenzene method for creating the accelerator M is not ideal for industrialized large application as a result of the hi gh rate of raw materials as well as difficult manufacturing procedure; the mixed method of nitrogen and also aniline has low production price, as well as can make the H2S produced by the response more powerful than aniline. Nevertheless, because of the issues of difficult control of the reaction and high demands on the material of the reactor, this method is seldom made use of in China presently. As a result, the synthesis of aniline to advertise M is the approach frequently made use of by different complementary manufacturers.

Application of 2-Mercaptobenzothiazole

2-Mercaptobenzothiazole (MBT) is an important part of benzothiazole compounds and has a wide range of application values in industry, agriculture and medical fields.

  • In the mineral processing industry, MBT is often used for pre-concentration and separation of precious metals and transitional metal elements. It is a flotation collector for sulfide ore, pyrite, and precious metal ore. It is also used for the metal surface of copper and its alloys. It is an effective copper corrosion inhibitor.
  • In the analytical chemistry industry, MBT has good selective adsorption for metal ions, and almost all transition elements can form stable complex M with it, as an important reagent for the determination of copper, lead, silver, gold, cobalt and calcium It is therefore effectively utilized in analytical chemistry applications and industrial water treatment.
  • In the rubber industry, MBT is a general-purpose rubber vulcanization accelerator, combined with unsaturated vulcanized polymers to form an elastic cross-linked material, referred to as vulcanization accelerator M, which has fast vulcanization acceleration, good vulcanization flatness and mixing It has the characteristics of no early vulcanization and other characteristics, and is widely used in the field of rubber processing industry. It has a rapid acceleration effect on natural rubber and general sulfur vulcanized synthetic rubber, and its vulcanization critical temperature is low. As an acid vulcanization accelerator, it can make rubber products have high tensile strength and hardness. By choosing different components, it can also meet different requirements. It can be used as a plasticizer to increase the plasticity of natural rubber.
    However, the product itself has a bitter taste and is not suitable for the manufacture of rubber products in contact with food. It is mainly used for the manufacture of tires, inner tubes, tapes, rubber shoes and industrial products. The object rubbers that can be added are: natural rubber (NR), isoprene rubber (IR), styrene-butadiene rubber (SBR), butadiene rubber (BR), nitrile rubber (NBR), EPDM rubber ( EPDM), butyl rubber (IIR), etc. The dosage (ph r) in rubber is 0.5-2.
  • In the field of agricultural products, MBT can be used as herbicide and insecticide, plant growth regulator, etc.
  • Medical field: US FDA approved 2-Mercaptobenzothiazole for veterinary clinical use in the treatment of skin infection in pets.

The Main Application of Accelerator M

Accelerator m is a general-purpose rubber vulcanization accelerator, a semi-super accelerator, which can be used alone or mixed with other accelerators. It has a rapid acceleration effect on natural rubber and general sulfur vulcanized synthetic rubber.

Accelerator m is the parent material of most sulfenamide accelerators, and is a widely used organic intermediate synthetic accelerator NOBS, Ds, Ns, cz, D1Bs, Dz, Mz (2-mercaptobenzothiazole zinc salt ), DM, TBsliⅣ-tert-butyl-bis(2-benzothiazole)sulfenimide], cBBs[Ⅳcyclohexyl-bis(2-benzothiazole)sulfenamide], etc. The development of agent m. The quality and output of accelerator m are directly related to the development of rubber.

In the process of rubber mastication, adding a small amount of accelerator m can form a loose complex structure with sulfur, which can improve the plasticity of rubber, quickly reduce the Mooney viscosity of rubber, and can accelerate the mastication rate of raw rubber, reducing the The energy consumption of mastication shortens the time of mastication and greatly improves the efficiency of mastication.

Accelerator m can also effectively prevent corrosion of metals, etc.””. In various media, especially water, metal anticorrosion is often prevented by adding corrosion inhibitors, which is of great significance to the protection of cultural relics. It has been confirmed that benzoazole and some mercapto-substituted heterocyclic compounds, such as accelerator m, 2-mercaptobenzimidazole and 2-mercaptobenzoxazole, are effective corrosion inhibitors for metallic copper.

Another use of accelerator m is as a mineral flotation agent, mainly used as a collector for sulfide ore flotation such as silver, chalcopyrite, galena, pyrite and activated sphalerite, sometimes with dithioamino acid salts Mixed use can further improve the yield and grade of flotation products.

Accelerator m can also be used for epoxy resin modification. Adding a small amount of accelerator m to epoxy resin can significantly increase the adhesive strength and curing rate of epoxy resin, and has the effect of significantly reducing the reaction temperature and shortening the curing reaction time, and the larger the accelerator m, the faster the curing rate. This function has important guiding significance for fast industrial restoration, especially online industrial restoration.

Accelerator m can act as an initiator, increase the degree of polymerization of styrene, narrow the relative molecular mass distribution of the polymer, and the relative molecular mass of the polymer increases linearly with the increase of the conversion rate, showing that styrene is promoting In the presence of agent m, it has “active” and controllable polymerization characteristics” 2’4…. This has certain guiding significance for the preparation of special materials in the FRP industry, especially in the aerospace industry.

Accelerator m is used as an extraction agent and is currently mainly used for the separation of precious metal rhodium and iridium. The lone electrons attached to the sulfur and nitrogen molecules in the hydrogen accelerator can easily form coordination with precious metals, which solves the problem that the two precious metals, rhodium and iridium, are difficult to separate.

Accelerator m can be used as a lubricant as well as an adsorbent. It also has its special application in electrochemistry. For example, adding a small amount of accelerator m to the electrode material can change the performance of the electrode, which is of great significance to the development of electrochemistry.
