2-Methylcyclohexanone Chemical Properties,Uses,Production

Chemical Properties

CLEAR COLOURLESS TO VERY SLIGHTLY YELLOW LIQUID

Chemical Properties

o-Methylcyclohexanone is a colorless liquid with a weak peppermint-like odor (also reported to be acetone-like).

Chemical Properties

2-Methylcyclohexanone has a weak, peppermint odor and burning sensation

Physical properties

Colorless liquid with a weak, peppermint-like odor.

Occurrence

Reported found in cockroaches as attractant pheromone; not reported found in natural foods

Uses

o-Methyl cyclohexanone is used as a solventfor varnishes, lacquers, and plastics; and asa rust remover.

Uses

2-Methylcyclohexanone can be used as solvent, lacquers.

Preparation

From cyclohexanone by treatment with a base and then with methyl iodide

General Description

A water-white to pale yellow liquid with an acetone-like odor. Less dense than water. Vapors heavier than air. Flash point near 135°F. May be toxic by ingestion. Used as a solvent.

Air & Water Reactions

Flammable. Slightly soluble in water.

Reactivity Profile

Contact with strong oxidizers may cause fires and explosions [USCG, 1999].

Hazard

Moderate fire risk. Toxic by ingestion,inhalation, and skin absorption. Eye and upper res-piratory tract irritant, and central nervous systemimpairment.

Health Hazard

May cause irritation of the eyes, nose and throat. Prolonged or repeated contact may cause dermatitis.

Health Hazard

o-Methyl cyclohexanone is a mildly toxiccompound. Any health hazard from inhalingits vapors is low. Its vapors at highconcentrations in air can be irritating to theeyes, nose, and throat. Ingestion of the liquidcan cause sleepiness. Toxicity studies on animalssuggest that methyl cyclohexanone maycause an adverse effect on the lungs, kidney,and liver. An intravenous administration of270 mg/kg was lethal to mice.
LD50 value, intraperitoneal (mice): 200mg/kg.

Fire Hazard

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon monoxide, may be formed when involved in fire.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion and skin contact. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Methylcyclohexanone is used as a solvent in making varnish, plastics, and as a rust remover. Also used in the leather industry.

Shipping

UN2297 Methylcyclohexanone, Hazard Class: 3; Labels: 3-Flammable liquid.

Incompatibilities

Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact with peroxides may form unstable heat- and shock-sensitive explosives

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
