Sodium mercaptobenzothiazole Usage And Synthesis

Uses

copper corrosion inhibitor; plasticizer and photometer for acid copper plating.

Uses

sodium mercaptobenzothiazole solution, also known as sodium mbt50%, or simply mbt50, is a clear, amber 50% aqueous solution of sodium 2-mercaptobenzothiazole represented by the formula: (nac7h4ns2). mbt50 is used as a corrosion inhibitor and water treatment agent; biological activity indicates possible use as a bactericide or fungicide. it is also used as a chemical intermediate.

General Description

Sodium 2-mercaptobenzothiazol solution appears as an amber liquid with an odor of old rubber. A 50% aqueous solution. Denser than water. (USCG, 1999)

Air & Water Reactions

Sensitive to prolonged exposure to air. Water soluble.

Reactivity Profile

SODIUM 2-MERCAPTOBENZOTHIAZOL reacts vigorously with oxidizing materials (e.g. hydroperoxides). Liberates heat in contact with strong mineral acids or acid fumes .

Health Hazard

Contact with moisture in the body by inhalation may yield sodium hydroxide (corrosive) and 2-mercaptabenzothiazole, an irritant. Contact with the eyes caused opacity or ulceration of the cornea, inflammation of the iris, redness and swelling of the conjunctiva and partial eversion of the eye lids, and destruction or irreversible tissue change in 24 hours or less (rabbit). A dose of 2,500 mg/kg applied to the skin caused severe depression, cold extremities, appetite loss; 4 of 10 died. Exposure of the skin to 1,250 mg/kg caused a severe degree of skin injury. The skin was burned in 24 hours with formation of hard eschar at 1-2 weeks; 1 of 10 rabbits died. Ingestion caused tremors, convulsions, severe depression and hemaluria in male rats. Ingestion of 312.5 mg/kg: 1 of 5 male rats die on day 2; 625 mg/kg: 2 of 5 died within 3-5 minutes; 1,250 mg/kg: 3 of 5 died within 3-5 minutes; 2,500 mg/kg: 100% mortality within 3-5 minutes. Hemorrhage of the stomach occurred in all rats that died.

Contact allergens

Such mercaptobenzothiazole hydrosoluble salts are used as antioxidants and biocides in cutting fluids and greases, paints, or glues.

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits very toxic fumes of NOx, SOx, and NazO. See also MERCAPTANS.

Regulations

Sodium 2-mercaptobenzothiazole was first registered as a pesticide in the United States in 1949 in an industrial preservative product. Currently, only one product is registered, for use in wood and paper/paperboard treatment and as a preservative in metal working cutting fluids, emulsions, textiles and pastes.
