2-Mercaptobenzothiazole Chemical Properties,Usage,Production

Description

Mercaptobenzothiazole is a rubber chemical, an accelerant of vulcanization. It is contained in the "mercapto mix". The most frequent occupational categories are metal industry, homemakers, health services and laboratories, building industries, and shoemakers. It is also used as a corrosion inhibitor in cutting fluids or in releasing fluids used in the pottery industry.

Chemical Properties

beige or light yellow powder with a faint odour

Uses

antibacterial, antifungal. inhibits dopamine beta-hydroxylase

Uses

2-mercaptobenzothiazole is an accelerator, retarder, and peptizer for natural and other rubber products, such as shoes, gloves, rubber in undergarments and c1othing, condoms and diaphragms, medical devices, toys, tires and tubes, renal-dialysis equipment, swimwear; fungicide; corrosion inhibitor in soluble cutting oils and antifreeze mixtures; in greases, adhesives, photographic-film emulsions; detergents; veterinary products, such as tick and flea powders and sprays.

Uses

Vulcanization accelerator for type of rubber usually used in the production of household rubber gloves rather than medical rubber gloves; corrosion inhibitor in metal-working fluids, detergents, antifreeze, and photographic emulsions.

Definition

ChEBI: 1,3-Benzothiazole substituted at the 2-position with a sulfanyl group.

Synthesis Reference(s)

The Journal of Organic Chemistry, 26, p. 3436, 1961 DOI: 10.1021/jo01067a101

General Description

Pale yellow to tan crystalline powder with a disagreeable odor.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Mercaptobenzothiazole is incompatible with strong oxidizing agents. Also incompatible with acids and acid fumes .

Health Hazard

Thiazoles cause allergic skin reactions of type IV [delayed-type hypersensitivity (DTH)].

Fire Hazard

2-Mercaptobenzothiazole is combustible.

Contact allergens

MBT is a rubber chemical, accelerant of vulcanization, and contained in “mercapto-mix.” The most frequent occupational categories are the metal industry, homemakers, health services and laboratories, the building industry, and shoemakers. It is also used as a corrosion inhibitor in cutting fluids or in releasing fluids in thepottery industry

Safety Profile

Suspected carcinogen withexperimental carcinogenic and tumorigenic data. Poisonby ingestion and intraperitoneal routes. Experimentalteratogenic and reproductive effects. Mutation datareported. Incompatible with oxidizers. When heated todecomposition

Carcinogenicity

MBT was not mutagenic in Ames bacterial assays, but it induced chromosomal damage in mammalian cells in culture. Reproductive effects were not observed in two-generation studies of rats treated with up to 15,000 ppm MBT in the diet.

Purification Methods

Crystallise it repeatedly from 95% EtOH, or purify it by incomplete precipitation by dilute H2SO4 from a basic solution, followed by several crystallisations from acetone/H2O or *benzene. It complexes with Ag, Au, Bi, Cd, Hg, Ir, Pt, and Tl. [Beilstein 27 II 233, 27 III/IV 2709.]
