2-Methylcyclohexanol is a straw-colored liquid. Weak, menthol-like odor. The odor threshold is 490 ppm. (higher than the OEL).

??

Methylcyclohexanol is used as a blendingagent in textile soaps as an antioxidant inlubricants, and as a solvent for lacquers.

?? ??

Methylcyclohexanol is produced by hydrogenating m- and p-cresols. Methylcyclohexanol can exist as three separate isomers, ortho, meta, and para, or as a mixture of isomers. The commercial product consists essentially of the meta and para isomers. Methylcyclohexanol is used as a solvent in lacquers, a blending agent in textile soaps, and an antioxidant in lubricants. In addition, methylcyclohexanol dissolves gums, oils, resins, and waxes.

?? ??

Colorless viscous liquids with a menthol-like odor. Less dense than water. Flash point 136°F. Vapors heavier than air. May be toxic by ingestion. Used as a solvent and to make soaps and detergents.

??? ?? ??

Flammable. Soluble in water.

?? ???

METHYLCYCLOHEXANOL is incompatible with the following: Strong oxidizers .

???

Toxic by ingestion. Eye and upper respira-tory tract irritant.

????

Methylcyclohexanol is mildly toxic. Inhalationmay produce mild irritation of the eyesand the respiratory system, and headache.Studies in rabbits showed that this compoundcould cause rapid narcosis and convulsion atsublethal doses. The minimum lethal dose byoral administration was 2000 mg/kg. Severeexposure may produce narcosis in humans.Skin absorption may cause dermatitis.

????

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Safety Profile

Moderately toxic by ingestion and subcutaneous routes. Mildly toxic by skin contact. Human system effects by inhalation: antipsychotic, unspecified liver and kidney effects. Combustible when exposed to heat, flame, or oxidizers. On heating it emits acrid fumes; can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical.

??? ??

Methylcyclohexanol is used as a lacquer solvent; as a blending agent in textile soaps and as an antioxidant in lubricants.

?? ??

UN2617 Methylhexylhexanone, flammable, Hazard Class: 3; Labels: 3-Flammable liquid.

? ???

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. Attacks some plastics, rubber, and coatings.

??? ??

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
