• 化学的特性

  Anisidine exists as ortho-, meta-, and paraisomers. They have characteristic amine (fishy) odors. releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987).

• 物理的性質

  Yellow to light brown powder, leaflets, solid or crystals with a characteristic amine or ammonialike odor. soluble in ethanol and ether, slightly soluble in water.

• 使用

  p-Anisidine is used mostly for producing dyes, and some smaller quantities are employed in making pharmaceuticals and liquid crystals.

• 主な応用

  p-Anisidine is used as a reagent to indicate the secondary stage of the oxidation, it is one of the three possible isomers of the Anisidine or methoxyaniline. The other two isomers are o-Anisidine (2-methoxyaniline) and m-Anisidine (3-methoxyaniline).
  The p-anisidine is widely used as an intermediate in the production of numerous azo and triphenylmethane dyes, and pigments. It is also used in the production of pharmaceuticals including the guaiacol expectorant, as an antioxidant for polymercaptan resins, and as a corrosion inhibitor for steel. Apart from the beneficial use of p-anisidine, it is toxic for human beings. The acute exposure may cause skin irritation, whereas the chronic exposure may cause headaches, vertigo, and blood complications like sulfhemoglobin, and methemoglobin. The oral exposure to anisidine hydrochloride resulted in cancer of the urinary bladder in male and female rats.

• 製造方法

  p-Anisidine is an important intermediate for synthesis of dye, medicine and perfume. Traditional preparation of p-Anisidine uses iron powder or sodium sulfide as reductant, which produces a large amount of waste and results in serious environment pollution problem. Liquid phase catalytic hydrogenation is not only an environmentally benign technique but also of high yield.
