5-メチル-3-ヘプタノン 化学特性,用途語,生産方法

• 外観

  無色～ほとんど無色透明液体

• 用途

  食品添加物(香料),溶剤、NITE調査

• 化学的特性

  5-Methyl-3-heptanone is a colorless liquid of low volatility. It has an agreeable penetrating odor that resembles the essence of apricots and peaches. Threshold odor concentrations of 6 and ,5 ppm have been reported .

• 使用

  • 5-Methyl-3-heptanone can be converted into the corresponding gem-dihydroperoxide using aqueous hydrogen peroxide and chlorosulfonic acid as a catalyst at room temperature.
  • It can be reduced to its corresponding alcohol using sodium borohydride in urea/choline chloride eutectic salt.
  • It can undergo condensation with tert-butyl-sulfinamide to form the corresponding chiral tert-butyl-sulfinyl-ketimine, which can further react with ylides derived from trimethylsulfonium iodide and S-allyl tetrahydrothiophenium bromide to form highly substituted chiral aziridines.
  
  

• 調製方法

  U.S. production and importation of 5-methyl-2-heptanone was estimated to be relatively low (＜25,000 lb at a single site) in 2005 as data for 5-methyl-2-heptanone were not included in the 2006 U.S. EPA Inventory Update Reporting database.

• 健康ハザード

  Exposure to ethyl amyl ketone can causeirritation of the eyes, nose, and skin. Athigh concentrations its exposure can leadto ataxia, prostration, respiratory pain, andnarcosis. A 5-minute exposure to 50 ppmmay produce a mild irritating effect on theeyes and nose in humans. Inhalation of3000 ppm of ethyl amyl ketone for 4 hourswas highly toxic to mice, and 6000 ppm for8 hours was lethal to rats. The odor thresholdis 6 ppm.

• 火災危険

  Combustible liquid; flash point (open cup) 59°C (138°F); vapor density 2 torr at 25°C (77°F); fire-extinguishing agent: “alcohol” foam, dry chemical, or CO2; a water spray may be effective to cool it below its flash point. It forms explosive mixtures with air at elevated temperatures; the LEL and UEL values are not reported.

• 安全性プロファイル

  Moderately irritating to skin, eyes, and mucous membranes by inhalation and ingestion. Narcotic in high concentration. Flammable liquid when exposed to heat, sparks, or flame. When heated to decomposition it emits acrid smoke. To fight fire, use foam, CO2, dry chemical. See also KETONES.

• 環境運命予測

  Chemical/Physical. 5-Methyl-3-heptanone will not hydrolyze because it does not contain a hydrolyzable functional group.

• 廃棄物の処理

  Ethyl amyl ketone wastes can be destroyedby incineration or by treatment with moltenmetal salts.
