使用
3,5-Dimethylphenol finds application as adhesives, sealant chemicals, plating and surface treating agents. It is also used as a solvent for cleaning or degreasing. Further, it is employed as a chemical intermediate for antioxidants, phenolic resins, active pharmaceutical ingredients and metaxalone (muscle relaxant).
定義
ChEBI: A member of the class of phenols that phenol substituted by methyl groups at positions 3 and 5.
一般的な説明
Colorless to off-white crystalline solid. Odor threshold 1 ppm. Taste threshold 0.001 mg/L.
空気と水の反応
3,5-Dimethylphenol is hygroscopic. Insoluble in water.
反応プロフィール
3,5-Dimethylphenol is incompatible with bases, acid chlorides, acid anhydrides, and oxidizing agents. 3,5-Dimethylphenol corrodes steel, brass, copper, and copper alloys.
火災危険
Flash point data for 3,5-Dimethylphenol are not available. 3,5-Dimethylphenol is probably combustible.
安全性プロファイル
Poison by
intraperitoneal route. Moderately toxic by
ingestion. A severe eye irritant. Questionable
carcinogen with experimental tumorigenic
data. When heated to decomposition it
emits acrid smoke and irritating fumes. See
also other xylenol entries.
職業ばく露
3,5-Xylenol is used as an antioxidant,
solvent, plasticizer, wetting agent; and in pharmaceuticals.
Xylenols are also used in pesticides, fuel, and lubricant
