ar-メトキシベンゼンアミン 化学特性,用途語,生産方法

• 解説

  アニシジン．

  芳香族アミンの一つ。アミノアニソール、メトキシアニリンともいう。o(オルト)、m(メタ)、p(パラ)の3種の異性体がある。

  　いずれも、それぞれ対応するニトロアニソールを鉄、亜鉛などの金属と酸によって還元すると得られる。o-アニシジンおよびm-アニシジンは淡黄色の液体であるが、p-アニシジンは無色の固体である。各異性体とも水にはほとんど溶けないが、アルコール、エーテルなどの有機溶媒には溶ける。o-アニシジン、p-アニシジンはアゾ染料、ナフトール染料（アゾイック染料）の合成中間体としてとくに重要である。o-アニシジンは発癌(はつがん)性があるといわれている。

  いずれもニトロアニソールを還元してつくられ，おもにアゾ染料の中間体として用いられる．o-アニシジンは液体．融点5 ℃，沸点225．d1.092．n_D²⁰1.573．pKb 9.48．
  

• 化学的特性

  Anisidine exists as ortho-, meta-, and paraisomers. They have characteristic amine (fishy) odors.

• 一般的な説明

  A fused crystalline solid or a reddish to yellowish oily liquid. More dense than water and insoluble in water. Very irritating to skin, eyes, and mucous membranes. Toxic by ingestion and skin contact. Used to make dyes.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  An amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

• 健康ハザード

  TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

• 火災危険

  Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

• 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.

• 輸送方法

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

• 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.
