Uses and synthesis of 2-Mercaptobenzothiazole powder

2-Mercaptobenzothiazole powder is a chemical with the formula C7H5NS2. Light yellow powder. Has a slight odor and bitter taste. The density of pure products is 1.42; Melting point 178~180℃. The density of 2-Mercaptobenzothiazole is 1.40~1.48; Melting point 170~178℃. Soluble in propanol, ethanol, chloroform, ammonia, sodium hydroxide, sodium carbonate and other alkaline solutions, slightly soluble in benzene, insoluble in water and gasoline. 2-Mercaptobenzothiazole is mainly used as a vulcanization accelerator for rubber (accelerator M), but also as a pesticide fungicide, called nuodex or agent M. It can also be used as a corrosion inhibitor. 2-Mercaptobenzothiazole powder is also used as a special reagent for metals. It can be synthesized from aniline, carbon disulfide and sulfur, or carbon disulfide and diphenylthiourea, or o-nitrochlorobenzene, sodium hydrosulfide and carbon disulfide.

Applications/Functions of 2-Mercaptobenzothiazole powder

1. 2-Mercaptobenzothiazole powder is mainly used in the manufacture of tires, inner tubes, tape, rubber shoes and other industrial rubber products
2. 2-Mercaptobenzothiazole is one of the effective corrosion inhibitors for copper or copper alloys. When the cooling system contains copper equipment and the raw water contains a certain amount of copper ions, it can be added to prevent copper corrosion.
3. 2-Mercaptobenzothiazole is an intermediate of the herbicide benthiaclor, as well as a rubber accelerator and its intermediates.
4. 2-Mercaptobenzothiazole is mainly used as a solvent for polyurethane synthetic leather, amino acid synthetic leather, resin vegetable oil, mineral oil, medicine, paint and dyes, as a stabilizer for 1,1, 1-trichloroethane, and is also used as a plasticizer and antioxidant
5. 2-Mercaptobenzothiazole powder used as rubber accelerator; Used as an intermediate for cephalosporin and other drugs

Physicochemical Property of 2-Mercaptobenzothiazole powder

Yellowish monoclinic spicules or flaky crystals having an unpleasant odor. Insoluble in water and gasoline, soluble in ethanol, ether, acetone, ethyl acetate, benzene, chloroform and dilute lye.

Production methodprocess of 2-Mercaptobenzothiazole powder

The preparation method is to react 2-Mercaptobenzothiazole sodium salt with o-chloronitrobenzene, sodium polysulfide and carbon disulfide as raw materials at 110 ~ 130℃ and 343kPa pressure, and then acidified with sulfuric acid and washed to obtain 2-mercaptobenzothiazole powder.
