일반 설명

A clear colorless liquid. Flash point 126°F. Less dense than water and only slightly soluble in water. Hence floats on water. Vapors heavier than air. Density 6.8 lb / gal. Used as a synthetic flavoring and in perfumes.

공기와 물의 반응

Flammable. Slightly soluble in water.

반응 프로필

2-Heptanone reacts exothermically with many acids and bases to produce flammable gases (e.g., H2). The heat may be sufficient to start a fire in the unreacted portion. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. Incompatible with many oxidizing agents including nitric acid, nitric acid/hydrogen peroxide mixture, and perchloric acid. May form peroxides [USCG, 1999].

위험도

Moderate fire risk. Toxic by inhalation, skin and eye irritant, narcotic in high concentration.

건강위험

Inhalation can cause headache, fatigue, nausea, vomiting, dizziness, stupor, drowsiness, disturbed vision, and unconsciousness. Skin contact can cause moderate irritation, defatting, and dermatitis. Ingestion may cause irritation of lips and mouth, gastro-intestinal irritation, nausea, diarrhea, drowsiness, loss of consciousness, weak and rapid pulse, cold-pale complexion.

건강위험

Exposure to methyl amyl ketone causedirritation of mucous membranes, mild tomoderate congestion of the lungs, and narcosis in test animals. A 4-hour exposure to a4000-ppm concentration in air was lethal torats; 1500–2000 ppm produced lung irritation and narcosis. The concentration at whichit produces similar symptoms in humans isnot known.
The oral toxicity of this compound is low.Its irritant action on skin should be low tovery low.
LD50 value, oral (mice): 730 mg/kg.

화재위험

Combustible liquid, flash point (closed cup) 39.9°C (102°F), (open cup) 48.9°C (12°F); vapor density 3.9 (air = 1) vapor pressure 2.6 torr at 20°C (68°F); autoignition temperature 393°C (740°F); fire-extinguishing agent: “alcohol” foam; a water spray may be used to cool below its flash point.
Methyl amyl ketone forms an explosive mixture with air in the range 1.1% [at 66°C (150.8°F)] to 7.9% [at 121°C (249.8°F)] by volume. It can react explosively with strong acids, alkalies, and oxidizing agents.

Safety Profile

Moderately toxic by ingestion. Mildly toxic by inhalation and skin contact. A skin irritant. A flammable liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also KETONES.

Source

Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996). Also identified as a volatile constituent released by fresh coffee beans (Coffea canephora variety Robusta and Coffea arabica) at different stages of ripeness (Mathieu et al., 1998).

환경귀착

Biological. Heukelekian and Rand (1955) reported a 10-d BOD value of 0.50 g/g which is 17.8% of the ThOD value of 2.81 g/g.
Chemical/Physical. Atkinson et al. (2000) studied the kinetic and products of the gas-phase reaction of 2-heptanone with OH radicals in purified air at 25 °C and 740 mmHg. A relative rate constant of 1.17 x 10-11 cm3/molecule·sec was calculated for this reaction. Reaction products identified by GC, FTIR, and atmospheric pressure ionization tandem mass spectroscopy were (with respective molar yields): formaldehyde, 0.38; acetaldehyde, λ0.05; propanal, λ0.05; butanal, 0.07; pentanal, 0.09; and molecular weight 175 organic nitrates.
2-Heptanone will not hydrolyze because it does not contain a hydrolyzable functional group. Burns in air releasing carbon monoxide and carbon dioxide.

운송 방법

UN1110 n-Amyl Methyl ketone, Hazard Class: 3; Labels: 3-Flammable liquid.

Toxicity evaluation

2-Heptanone is metabolized in the liver and causes toxicity by oxidative and free radical mechanisms. It is known to potentiate both nephrotoxic and hepatotoxic effects of halogenated hydrocarbons.

폐기물 처리

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
