Methanol
Methyl Alcohol Pure Suppliers
Methanol or methyl alcohol is a liquid chemical with the formula CH3OH. It is a light, volatile, colorless, flammable liquid with a distinctive odor similar to that of ethanol or drinking alcohol. Methanol is however far more toxic than ethanol. Methanol is used as a solvent and as an antifreeze in pipelines and windshield washer fluid apart from several bulk uses. In some wastewater treatment plants, a small amount of methanol is added to wastewater to provide a carbon food source for the denitrifying bacteria, which convert nitrates to nitrogen gas and reduce the nitrification of sensitive aquifers. Methanol is also used as a de-staining agent.
Properties and General Specifications of Methanol or Methyl Alcohol:
Appearance: Colorless liquid.
Relative density: 0.79
Melting point: −98C.
Boiling point: 65C.
Flash point: 11C.
Solubility: miscible with water.
Purity on dry basis: 99.85% minimum.
Water 0.1% maximum.
Menthol USP Grade Specifications:
C10H20O --- 156.27
Cyclohexanol, 5-methyl-2-(1-methylethyl) --- CAS 1490-04-6.
Menthol is an alcohol obtained from diverse mint oils or prepared synthetically. Menthol may be levorotatory (l-Menthol), from natural or synthetic sources, or racemic (dl-Menthol).
Packaging and storage: Preserve in tight containers, preferably at controlled room temperature.
Labeling: Label it to indicate whether it is levorotatory or racemic.
Identification: When it is triturated with about an equal weight of camphor, of chloral hydrate, or of phenol, the mixture liquefies.
Melting range of l-Menthol: between 41 and 44 .
Congealing range of dl-Menthol: [NOTE—Perform this test preferably in a room having a temperature below 30 and a relative humidity below 50%.] Place about 10 g of racemic Menthol, previously dried in a desiccator over silica gel for 24 hours, in a dry test tube of from 18- to 20-mm internal diameter, and melt the contents at a temperature of about 40 . Suspend the test tube in water having a temperature of 23 to 25 , and stir the contents of the tube continually with a thermometer, keeping the bulb of the thermometer immersed in the liquid. Racemic Menthol congeals at a temperature between 27C and 28C. Shortly after the temperature has stabilized at the congealing point, add a few mg of dried racemic Menthol to the congealed mass, and continue the stirring: after a few minutes the temperature of the mass quickly rises to 30.5C to 32.0C.
Specific rotation: between 45 and 51 for l-Menthol; between 2 and +2 for dl-Menthol.
Test solution: 100 mg per mL, in alcohol.
Limit of nonvolatile residue: Volatilize 2 g, accurately weighed, in a tarred open porcelain dish on a steam bath, and dry the residue at 105 for 1 hour: the residue weighs not more than 1 mg (0.05%).
Chromatographic purity: To pass the test.
Readily oxidizable substances in dl-Menthol: Place 500 mg of dl-Menthol in a clean, dry test tube, add 10 mL of a solution of potassium permanganate, prepared by diluting 3 mL of 0.1 N potassium permanganate with water to 100 mL, and place the test tube in a beaker of water at a temperature between 45C and 50C. Remove the tube from the bath at intervals of 30 seconds, and mix quickly by shaking: the purple color of potassium permanganate is still apparent after 5 minutes.

5. Fire Fighting Measures
Flammability of the Product: Flammable.
Auto-Ignition Temperature: 455C.
Flash Points: 11C
Products of Combustion: Carbon dioxide, Carbon monoxide and fumes.
Fire: Inflammable.
Explosion: Explosive in presence of heat.
Fire Extinguishing Media: Use water spray, dry powder, alcohol resistant foam, carbon dioxide. Flammable liquid and vapor. Do not use a solid (straight) water stream as it may scatter and spread fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Avoid a solid water jet on the container in order to prevent any splashing of the product which could cause spreading of the fire. Cool containing vessels with water spray in order to prevent pressure build-up, auto-ignition or explosion.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures it may produce toxic or irritating fumes. Use water spray to cool unopened containers.
6. Accidental Release Measures
Personal precautions, protective equipment and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Avoid mist formation. Avoid breathing mist. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Remove all sources of ignition. Provide proper ventilation. Absorb the material on a porous, inert material such as earth, sand or vermiculite. Carefully sweep up or swab the material without causing dust/mist. Dispose of in accordance with local regulations.
Large liquid spillages should be contained by use of sand or another inert material. The spillage should be transferred to a suitable container and recovered or disposed of in accordance with local regulations.
7. Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Do not ingest. Do not breathe dust vapors or mist . Work under hood. Ensure proper ventilation. Provide appropriate exhaust ventilation at places where dust/mist is formed. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like oxidizing agents, metals, reducing agents, acids and halogen compounds.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
ACGIH: TWA: 200 ppm; STEL: 250 ppm
OSHA: PEL: 200 ppm.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
