2-Hexanone Chemical Properties,Uses,Production

Chemical Properties

2-Hexanone is a colorless to pale yellow liquid with a sharp odor. It dissolves very easily in water and is miscible in ethanol, methanol, and benzene. 2-Hexanone evaporates easily into the air as a vapor. It is stable, flammable, and incompatible with oxidizing agents, strong bases, and reducing agents. 2-Hexanone is a waste product of wood pulping, coal gasifi cation, and oil shale operations. Formerly, 2-hexanone was in use as a paint and paint thinner with other chemical substances, and to dissolve oils and waxes.and is used as a solvent and organic syn- thesis intermediates. However, the industrial uses of 2-hexanone is now very much restricted.

Chemical Properties

MNBK is a colorless liquid with an acetonelike odor. The odor threshold is 0.08 ppm.

Physical properties

Clear, colorless to pale yellow, flammable liquid with an odor resembling acetone and 2-butanone. Nagata and Takeuchi (1990) reported an odor threshold concentration of 24 ppbv. Amoore and Hautala (1983) reported odor threshold concentrations of 250 μg/L and 76 ppbv in water and air, respectively.

Uses

Methyl butyl ketone (MBK) is used as asolvent for nitrocellulose, resins, lacquers,oils, fats, and waxes.

Uses

2-Hexanone is used in various organic chemical syntheses. It is used in the synthesis of (+/-)-monomorine. It is also used in the preparation of alcohols by transfer hydrogenation of ketones.

Production Methods

MnBK can be produced by a reaction between acetic acid and ethylene under pressure MnBK can be produced by a reaction between acetic acid and ethylene under pressure.

General Description

A clear colorless liquid. Flash point 95°F. Less dense than water. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

2-Hexanone is incompatible with oxidizing agents. 2-Hexanone may also react with strong bases and reducing agents.

Hazard

Flammable, moderate fire risk, explosive limits 1.2–8% in air. Irritant to eyes and mucous membranes, narcotic in high concentration, absorbed by skin. Causes peripheral neuropathy and testicular damage.

Health Hazard

Inhalation of high concentrations of vapor may result in narcosis; peripheral neuropathy may develop. Ingestion of large amounts may cause some systemic injury. Contact with eyes causes mild to moderate irritation. Liquid irritates skin; prolonged or repeated contact may cause defatting of the skin with resultant dermatitis.

Health Hazard

Chronic exposure to MBK via inhalationor skin absorption can cause disordersof the peripheral nervous system andneuropathic diseases. The symptoms inhumans, depending on the severity ofexposure, were parasthesias in the handsor feet, muscle weaknesses, weakness inankles and hand, and difficulty in grasping heavy objects. Animal studies indicatethat prolonged exposure to this compoundat a concentration of 200–1300 ppm for4–12 weeks can result in neuropathy.Neurotoxicity is attributed to its primarymetabolite, 2,5-hexanedione. Improvementin conditions can occur slowly over monthsafter cessation of exposure. Acute exposureto high concentrations, 1000 ppm, for severalminutes can cause irritation of the eyes andnose in humans. Inhalation to 20,000 ppmfor 30 minutes caused narcosis in guineapigs and prolonged exposure for 70 minuteswas lethal. The acute oral toxicity in ratswas low.
LD50 value, oral (rats): 2600 mg/kg.

Fire Hazard

2-Hexanone is flammable.

Potential Exposure

The material is used as a solvent

Environmental Fate

Biological. Using the BOD technique to measure biodegradation, the mean 5-d BOD value (mM BOD/mM 2-hexanone) and ThOD were 5.22 and 61.4%, respectively (Vaishnav et al., 1987).
Photolytic. A second-order photooxidation rate constant of 8.97 x 10-12 cm3/molecule?sec for the reaction of 2-hexanone and OH radicals in the atmosphere at 299 K was reported by Atkinson (1985).
Chemical/Physical. 2-Hexanone will not hydrolyze because it has no hydrolyzable functional group (Kollig, 1995).

storage

2-Hexanone should be kept stored in a tightly closed container, in a cool, dry place, away from sources of ignition.

Shipping

UN1224 Ketones, liquid, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required

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.

Precautions

Occupational workers should be careful when using and handling 2-hexanone. Workers should wash thoroughly after handling the chemical substance. Workers should avoid contact of 2-hexanone with the eyes, skin, and clothing and also avoid contact with heat, sparks, and flame.
