  無色～黄褐色, 澄明の液体

• 溶解性

  エタノール及びアセトンに極めて溶けやすく、水にわずかに溶ける。

• 化学的特性

  2,4-Dimethylphenol is a clear colorless to yellow liquid or needle crystals. miscible with alcohol and ether, slightly soluble in water.It has a moderate mammalian oral toxicity and is a recognised irritant.

• 物理的性質

  Colorless solid, slowly turning brown on exposure to air.

• 使用

  2,4-dimethylphenol is a fungicide and disinfectant with a variety of agricultural uses. It is also used in making wetting agent; dyestuffs; phenolic antioxidants; pharmaceuticals; rubber chemicals; lubricant ; gasoline additive and plasticizers.

• 製造方法

  synthesis of 2,4-dimethylphenol: 2,4-Dimethylphenol is obtained by sulfonation, salting out, alkali melting and acidification of m-xylene.

• 定義

  ChEBI: 2,4-xylenol is a member of the class of phenols that phenol substituted by methyl groups at positions 2 and 4. It has a role as a disinfectant and a volatile oil component. It is a member of phenols and an aromatic fungicide. It derives from a hydride of a m-xylene.

• 一般的な説明

  2,4-dimethylphenol appears as colorless crystals or clear, dark amber liquid.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  2,4-Dimethylphenol is a very weak acid (pKa = 10.6) . Incompatible with acid chlorides, acid anhydrides, bases and oxidizing agents. Corrodes steel, brass, copper and copper alloys .

• 健康ハザード

  2,4-Dimethylphenol is expected to be an irritant of the eyes, mucous membranes, and skin, by analogy to other phenols.
  The oral LD50 for rats was 3.2 g/kg; the dermal LD50 in mice was 1.04 g/kg.

• 火災危険

  2,4-Dimethylphenol is probably combustible.

• 安全性プロファイル

  Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion and skin contact. Questionable carcinogen with experimental carcinogenic data. When heated to decomposition it emits acrid smoke and irritating fumes. See also other xylenol entries.

• 発がん性

  2,4-Dimethylphenol was tested for mutagenicity in the Salmonella microsome preincubation assay using the standard protocol of the National Toxicology Program and five strains of Salmonella; results were negative.
  The ACGIH has not established a threshold limit value (TLV) for 2,4-dimethylphenol.

• 環境運命予測

  Biological. When 2,4-dimethylphenol was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum, significant biodegradation with rapid adaptation was observed. At concentrations of 5 and 10 mg/L, 100 and 99% biodegradation, respectively, were observed after 7 d (Tabak et al., 1981).
  Photolytic. 2,4-Dimethylphenol absorbs UV light at a maximum wavelength of 277 nm (Dohnal and Fenclová, 1995).
  Chemical/Physical. Wet oxidation of 2,4-dimethylphenol at 320 °C yielded formic and acetic acids (Randall and Knopp, 1980). 2,4-Dimethylphenol will not hydrolyze because there is no hydrolyzable functional group (Kollig, 1993).
