Description

2-Heptanone has a characteristic banana, slightly spicy odor

Chemical Properties

2-Heptanone has a fruity, spicy, cinnamon, banana, slightly spicy odor.

Chemical Properties

colourless liquid

Chemical Properties

Methyl amyl ketone is a clear colorless liquid with a mild, banana-like odor.

Physical properties

Colorless liquid with a banana-like odor. Can be detected at a concentration of 140 μg/kg (Buttery et al., 1969a). Cometto-Mu?iz et al. (2000) reported nasal pungency threshold concentrations ranging from approximately 195 to 935 ppm. An odor threshold concentration of 6.8 ppbv was reported by Nagata and Takeuchi (1990).

Occurrence

Reported found in clove essential oil, Ceylon cinnamon and rancid coconut oil; also identifed in Ruta Montana Also reported found in banana, lingonberry, loganberry, black currant, guava, grapes, papaya, peach, pear, raspberry, other berries, strawberry jam, asparagus, roasted onion, leek, baked potato, mushroom, clove bud, ginger, blue, cheddar and Swiss cheeses, milk, cream, butter, fsh, meats, hop oil, beer, brandy, rum, malt whiskey, grape wines, cocoa, coffee, tea, peanuts, pecans, walnut, oats, soybeans, coconut oil, olive, passion fruit, mango, fgs, rice, sweet corn, corn tortillas, malt, caviar, shrimp, oysters, crab, crayfsh and mate

Hazard

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

Health Hazard

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.

Health Hazard

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 irrita[1]tion 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.

Fire Hazard

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 tempera[1]ture 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.

Shipping

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

Waste Disposal

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.
