エチルアルミニウムセスキクロライド 化学特性,用途語,生産方法

• 化学的特性

  clear colorless solution

• 使用

  Catalyst for olefin polymerization, aromatic hydrogenation; intermediate.

• 調製方法

  Ethyl chloride and aluminum could used as starting metarials to synthesize Ethylaluminum sesquichloride. A 9.5 × 10^-2 m³ closed steel reactor, fitted with a reflux condenser and equipped for vacuum distillation of product, was first purged with nitrogen. After addition of 13.6 kg of aluminum powder and a catalyst mixture composed of 3.6 kg diethylaluminum chloride and 410 g iodine, the reactor contents were stirred and heated slowly to 130 ℃. The temperature was maintained at 120 – 150 ℃ during addition of 50 kg ethyl chloride over a period of 3 h. The product can be flash distilled under vacuum, or it can be drained from the reactor and clarified by settling or by filtration of black residual metal solids. Iodine can be omitted from the procedure, in which case the induction period may be increased.
  

• 一般的な説明

  A clear yellow liquid. Slightly denser than water. Used to make other chemicals.

• 空気と水の反応

  Spontaneously flammable in air (Douda 1966). Reacts violently with water forming hydrogen chloride and flammable ethane gas (Rose 1961).

• 反応プロフィール

  Organometallics, such as ETHYLALUMINUM SESQUICHLORIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water. A mixture of ETHYLALUMINUM SESQUICHLORIDE with carbon tetrachloride exploded when warmed to room temperature [Bretherick, 5th Ed., 1995].

• 危険性

  Ignites on contact with air, dangerous fire risk, reacts violently with water.

• 健康ハザード

  Inhalation of smoke from fire causes metal-fume fever (flu-like symptoms); acid fumes irritate nose and throat. Contact with liquid, which is spontaneously flammable, causes severe burns of eyes and skin.

• 安全性プロファイル

  Mixtures with carbon tetrachloride explode at room temperature. When heated to decomposition it emits toxic fumes of Cl-. See also ALUMINUM COMPOUNDS.

• 職業ばく露

  These materials are used as components of olefin polymerization catalysts. The reader is referred to the entry on “Aluminum alkyls” for additional information on this entry. The aluminum alkyl halides parallel very closely the aluminum alkyls

• 輸送方法

  UN3052 Spontaneously combustible. Water reactive releasing large quantities of toxic and deadly hydrogen gas. (Note: this number does not appear in the 49/CFR HazMat tables)

• 不和合性

  The aluminum alkyl halides are strong reducing agents; they react—possibly violently—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. These chemicals react violently with nitromethaneEthylaluminum sesquichloride reacts explosively with carbon tetrachloride at room temperature. This chemical reacts violently with water, forming corrosive hydrogen chloride and flammable ethane gas. Diethylaluminum chloride may form an explosive product with chlorine azide.
