Chemische Eigenschaften
white to almost white crystals or crystalline
Verwenden
Protection of light-colored rubber from oxidation and of nonstaining neoprene compounds against deterioration.
Verwenden
4,4''-Thiobis(2-tert-butyl-5-methylphenol) is an antioxidant. 4,4''-Thiobis(2-tert-butyl-5-methylphenol) is a radical inhibitor which prevented thermal decomposition of the peracid.
Verwenden
As an antioxidant in the rubber and plastics industry; as a stabilizer in polyethylene and polyolefin packaging materials for foodstuffs.
Allgemeine Beschreibung
White or light gray to tan powder.
Air & Water Reaktionen
Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water.
Reaktivität anzeigen
4,4'-Thiobis(6-tert-butyl-m-cresol) may be sensitive to light.
Hazard
Toxic by inhalation. Upper respiratory tract irritant. Questionable carcinogen.
Health Hazard
4,4'-Thiobis(6-tert-butyl-mcresol) (TBBC) is of low systemic toxicity in animals; allergic contact dermatitis has been reported in humans.
Brandgefahr
4,4'-Thiobis(6-tert-butyl-m-cresol) is combustible.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
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.
mögliche Exposition
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.
Inkompatibilitäten
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.
