5-메틸-3-헵탄온 C화학적 특성, 용도, 생산
화학적 성질
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 .용도
- 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.
생산 방법
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.건강위험
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.화재위험
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.Safety Profile
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.환경귀착
Chemical/Physical. 5-Methyl-3-heptanone will not hydrolyze because it does not contain a hydrolyzable functional group.폐기물 처리
Ethyl amyl ketone wastes can be destroyedby incineration or by treatment with moltenmetal salts.5-메틸-3-헵탄온 준비 용품 및 원자재
