| | METHYLCYCLOHEXANOL Usage And Synthesis |
| Description | 2-Methylcyclohexanol is a straw-coloredliquid with a weak, menthol-like odor. The odor thresholdis 490 ppm (higherthan theOEL). Molecularweight= 114.21; Specific gravity (H2O:1)= 0.92; Boilingpoint= 155- 180℃ (technical grade); Freezing/Meltingpoint= -50C; Vapor pressure = 2 mmHg at 30℃; Flashpoint= 65- 68℃; Autoignitiontemperature = 296℃.Hazard Identification (based on NFPA-704 M RatingSystem): Health 0, Flammability 2, Reactivity 0. Slightlysoluble in water. | | Chemical Properties | Colorless, viscous liquid; aromaticmenthol-like odor. Combustible. | | Chemical Properties | 2-Methylcyclohexanol is a straw-colored liquid.
Weak, menthol-like odor. The odor threshold is 490 ppm.
(higher than the OEL). | | Uses | Solvent for lacquers; blending agent in
textile soaps; antioxidant in lubricants | | Uses | Solvent for cellulose esters and ethers and forlacquers, antioxidant for lubricants, blending agentfor special textile soaps and detergents. | | Uses | Methylcyclohexanol is used as a blendingagent in textile soaps as an antioxidant inlubricants, and as a solvent for lacquers. | | Production Methods | 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. | | General Description | 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. | | Air & Water Reactions | Flammable. Soluble in water. | | Reactivity Profile | METHYLCYCLOHEXANOL is incompatible with the following: Strong oxidizers . | | Hazard | Toxic by ingestion. Eye and upper respira-tory tract irritant. | | Health Hazard | May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | | Health Hazard | 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. | | Fire Hazard | 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. | | Potential Exposure | Methylcyclohexanol is used as a lacquer solvent; as a blending agent in textile soaps and as an
antioxidant in lubricants. | | First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. | | 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. Methylcyclohexanolmust be stored to avoid contact with strong oxidizers (suchas peroxides, chlorates, perchlorates, nitrates, and permanganates), since violent reactions occur. Sources of ignition,such as smoking and open flames, are prohibited wheremethylcyclohexanol is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard. | | Shipping | UN2617 Methylhexylhexanone, flammable,
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. Attacks some plastics, rubber, and
coatings. | | 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 |
