• 説明

  o-Anisidine was produced commercially in the United States from the 1920s until late 1950s. By 2009, worldwide only six industries manufactured o-anisidine, but none produced hydrochloride salt. o-Anisidine was available from 44 suppliers, including 20 US suppliers, and the hydrochloride salt was available from eight suppliers, including five US suppliers. US imports of o-anisidine and its hydrochloride salt are reported in the category ‘o-anisidines, p-anisidines, and p-phenetidine,’ and US exports are reported in the category ‘anisidines, dianisidines, phenetidines, and their salts.’ From 1989 to 2008, imports ranged from a high of over 4.6 million kg in 1996 to zero in 2007 and 2008, and exports ranged from zero to 262 000 kg. Reports filed under the US Environmental Protection Agency’s (EPA) Toxic Substances Control Act Inventory Up Rule indicated that United States production plus imports of o-anisidine totaled 500 000 lb–1 million lb in 1986, 1990, and 2006; 1 million–10 million lb in 1990 and 1998; and 10 000–500 000 lb in 2002.

• 化学的特性

  Anisidine exists as ortho-, meta-, and paraisomers. They have characteristic amine (fishy) odors.
  o-Anisidine (or o-methoxyaniline) is an aromatic amine with a methoxyl group ortho to the amino group of aniline. It is a colorless to yellowish, pink, or reddish liquid.o-Anisidine is soluble in water and mineral oils, and miscible with alcohol, benzene, acetone, and diethylether. o-Anisidine hydrochloride, a salt of o-anisidine, is a grayish crystalline solid or powder at room temperature and is soluble in water (NTP, 2011).

• 物理的性質

  Colorless, yellow to reddish liquid with an amine-like odor. Becomes brown on exposure to air.

• 使用

  Similar to other aromatic amines, o-anisidine may cause methemglobinemia and cancer in humans. It is used mainly as an intermediate for the production of azo dyes and pigments. Other industrial uses of o-anisidine include synthesis of other dyes and pharmaceuticals, as a corrosion inhibitor for steel, and as an antioxidant for polymercaptan resins (IARC, 1999; HSDB, 2012).
  Intermediate for azo dyes and for guaiacol.

• 一般的な説明

  Clear, yellowish to reddish or brown liquid with an amine (fishy) odor.

• 空気と水の反応

  o-Anisidine darkens on exposure to air. Insoluble in water.

• 反応プロフィール

  o-Anisidine is sensitive to heat. o-Anisidine is also sensitive to exposure to light. o-Anisidine is incompatible with strong oxidizers. o-Anisidine is also incompatible with acids, acid chlorides, acid anhydrides and chloroformates. o-Anisidine will attack some forms of plastics, rubber and coatings. .

• 危険性

  Strong irritant. Toxic when absorbed through the skin. Possible carcinogen.

• 健康ハザード

  o-Anisidine was carcinogenic in experimental animals.

• 火災危険

  o-Anisidine is combustible.

• 安全性プロファイル

  Confirmed carcinogen. Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

• 職業ばく露

  Anisidines are used in the manufacture of azo dyes; pharmaceuticals; textile-processing chemicals Incompatibilities: 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. Attacks some coatings and some forms of plastic and rubber.

• 発がん性

  o-Anisidine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity in experimental animals.

• 環境運命予測

  Biological. o-Anisidine should be biodegradable according to OECD guidelines (Brown and Labouerer (1983). Chemical/Physical. At influent concentrations (pH 3.0) of 10, 1.0, 0.1, and 0.01 mg/L, the GAC adsorption capacities were 52, 20, 7.8, and 3.0 mg/g, respectively. At pHs 7 and 9, the GAC adsorption capacities were 110, 50, 23, and 10 mg/g at influent concentrations of 10, 1.0, 0.1, and 0.01 mg/L, respectively (Dobbs and Cohen, 1980).

• 輸送方法

  UN2431 Anisidines, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

• 純化方法

  It is separated from the m-and p-isomers by steam distillation. It is also separated from its usual synthetic precursor o-nitroanisole by dissolving it in dilute HCl (pH <2.0) extracting the nitro impurity with Et2O, adjusting the pH to ~8.0 with NaOH, extracting the amine into Et2O or steam distilling. Extract the distillate with Et2O, dry the extract (Na2SO4), filter, evaporate and fractionate the residual oil. Protect the almost colourless oil from light which turns it yellow in color.

• 廃棄物の処理

  Dissolve in combustible solvent (alcohols, benzene, etc.) and spray solution into furnace equipped with afterburner and scrubber, or burn spill residue on sand and soda ash absorbent in a furnace.
