1,1'-Thiobis(2-methyl-4-hydroxy-5-tert-butylbenzene)

???? C??? ??, ??, ??

??? ??

white to almost white crystals or crystalline

??

4,4''-Thiobis(2-tert-butyl-5-methylphenol) is an antioxidant in the rubber and plastics industry. 4,4''-Thiobis(2-tert-butyl-5-methylphenol) is a radical inhibitor which prevents the thermal decomposition of the peracid. In addition, it is used as a stabilizer in polyethylene and polyolefin packaging materials for foodstuffs. Protection of light-colored rubber from oxidation and of nonstaining neoprene compounds against deterioration.

?? ??

White or light gray to tan powder.

??? ?? ??

Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water.

?? ???

4,4'-Thiobis(6-tert-butyl-m-cresol) may be sensitive to light.

???

Toxic by inhalation. Upper respiratory tract irritant. Questionable carcinogen.

????

4,4'-Thiobis(6-tert-butyl-mcresol) (TBBC) is of low systemic toxicity in animals; allergic contact dermatitis has been reported in humans.

????

4,4'-Thiobis(6-tert-butyl-m-cresol) is combustible.

Safety Profile

Poison by intraperitoneal route and probably by ingestion and inhalation. Mutation data reported. See also SULFIDES. When heated to decomposition it emits highly toxic fumes of SOx.

??? ??

This material is used as an antioxidant in the plastics and rubber industries; in Neoprene and other synthetic rubbers; in polyethylene and polypropylene.

Carcinogenicity

TBBC was not mutagenic in Salmonella typhimurium strains with or without metabolic activation. In Chinese hamster ovary cells, TBBC induced an increase in sister chromatid exchanges but there were no increases in chromosomal aberrations.

? ???

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May evolve explosive hydrogen sulfide upon contact with moisture or acids.
