使用
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.
一般的な説明
White or light gray to tan powder.
空気と水の反応
Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water.
反応プロフィール
4,4'-Thiobis(6-tert-butyl-m-cresol) may be sensitive to light.
危険性
Toxic by inhalation. Upper respiratory tract
irritant. Questionable carcinogen.
健康ハザード
4,4'-Thiobis(6-tert-butyl-mcresol)
(TBBC) is of low systemic toxicity in
animals; allergic contact dermatitis has been
reported in humans.
火災危険
4,4'-Thiobis(6-tert-butyl-m-cresol) is combustible.
安全性プロファイル
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.
職業ばく露
This material is used as an antioxidant in the plastics and rubber industries; in Neoprene and other synthetic rubbers; in polyethylene and polypropylene.
発がん性
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.
不和合性
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.
