| Hazard Information | Back Directory | [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. | [Reactivity Profile]
Contact with strong oxidizers may cause fires and explosions [USCG, 1999]. | [Air & Water Reactions]
Flammable. Slightly soluble in water. | [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. | [Potential Exposure]
Methylcyclohexanone is used as a solvent in making varnish, plastics, and as a rust remover.
Also used in the leather industry. | [Fire Hazard]
Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon monoxide, may be formed when involved in fire. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [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 | [Description]

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). | [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 | [Physical properties]
Colorless liquid with a weak, peppermint-like odor. | [Occurrence]
Reported found in cockroaches as attractant pheromone; not reported found in natural foods | [Preparation]
From cyclohexanone by treatment with a base and then with methyl iodide | [Production Methods]
2-Methylcyclohexanone is manufactured by the catalytic
hydrogenation of o-cresol or by the dehydrogenation of
o-methylcyclohexanol. Methylcyclohexanones are
used in small amounts as general purpose solvents for
cellulose-based finishes and coatings. | [Synthesis Reference(s)]

Flammable | [storage]
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. o-methylcyclohexanonemust be stored to avoid contact with strong oxidizers (suchas chlorine, bromine, and fluorine) because violent reactionsoccur. Sources of ignition, such as smoking and openflames, are prohibited where o-Methylcyclohexanone isused, handled, or stored in a manner that could create apotential fire or explosion hazard. Metal containers involving the transfer of 5 gallons or more of this chemical shouldbe grounded and bonded. Drums must be equipped withself-closing valves, pressure vacuum bungs, and flamearresters. Use only nonsparking tools and equipment, especially when opening and closing containers of this chemical. Wherever this chemical is used, handled, manufactured,or stored, use explosion-proof electrical equipment andfittings. |
