ヘキサメチレンイミン 化学特性,用途語,生産方法

• 外観

  無色〜黄色, 澄明の液体

• 溶解性

  水、エタノール及びアセトンに極めて溶けやすい。

• 用途

  化学中間体、ゴム薬品、農業薬品

• 用途

  有機合成原料。

• 化学的特性

  clear colorless to light yellow liquid

• 使用

  Hexamethyleneimine is used as a pharmaceutical product and raw material for rubber products. It is also used as a intermediate for agrochemicals, zeolites, dyes , inks, rubber chemicals, textile chemicals, corrosion inhibitors, ore flotation.

• 定義

  ChEBI: An azacycloalkane that is cycloheptane in which one of the carbon atoms is replaced by a nitrogen atom.

• 調製方法

  Hexamethyleneimine is produced in 84% yield by heating hexamethylenediamine at 350 ℃ in a stream of hydrogen. The catalyst, ammonium vanadate on activated alumina, is prereduced with hydrogen at 500 ℃. Residues from the industrial distillation of hexamethylenediamine can be converted into hexamethyleneimine over aluminum silicate or aluminum oxide in a stream of nitrogen. For the preparation from caprolactam]. Hexamethyleneimine can be prepared by dimerizing acrolein, reducing the product to 2- hydroxymethyltetrahydropyran, expanding the ring to give oxepane, followed by treatment with ammonia over aluminum oxide at 350 ℃.
  

• 主な応用

  The most important use is the conversion of hexamethyleneimine into S-ethylhexahy- dro-1H-azepine-1-carbothioate, the selective rice herbicide Molinate (C2H5 S–CO–NC6H12 , Zeneca).
  

• 一般的な説明

  A colorless liquid with an ammonia-like odor. Flash point 65°F. Toxic by ingestion. Corrosive to metals and tissue. Combustion produces toxic oxides of nitrogen.

• 空気と水の反応

  Highly flammable. Soluble in water.

• 反応プロフィール

  Hexamethyleneimine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.

• 危険性

  Toxic by ingestion, strong irritant to tissue.

• 健康ハザード

  Inhalation of vapor irritates respiratory tract; high concentrations may cause disturbance of the central nervous system. Ingestion causes burns of mouth and stomach. Contact with concentrated vapor may cause severe eye injury. Contact with liquid causes burns of eyes and skin.

• 化学反応性

  Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

• 純化方法

  Purify azepane by dissolving in Et2O and adding ethanolic HCl until all the base separates as the white hydrochloride, filter, wash with Et2O and dry it (m 236o). The salt is dissolved in the minimum volume of H2O and basified to pH ~ 14 with 10N KOH. The solution is extracted with Et2O, the extract is dried over KOH, evaporated and distilled. The free base is a FLAMMABLE and TOXIC liquid, and best kept as the salt. The nitrate has m 120-123o, the picrate has m 145-147o, and the tosylate has m 76.5o (ligroin).
