  • Uses Methanol is an important chemical raw material for fine chemicals. Its carbonylation at 3.5 MPa and 180-200° C in the presence of catalyst can produce acetic acid and further produce acetic anhydride. It reacts with syngas to prepare vinyl acetate in the presence of catalyst; reacts with isobutylene to produce tert-butyl methyl ether; prepare dimethyl oxalate through oxidization and carbonylation, and a further hydrogenation to produce ethylene glycol; reacts with toluene under catalyst and simultaneous oxidization to produce phenylethyl alcohol. It can be used as a good solvent, as a pesticide raw material, as an antifreeze agent, as a fuel and fuel additive (this is receiving increasing attention in environmental protection field). It is the main raw material in the preparation of formaldehyde, the raw material in medicine and spices production, a solvent in dyes and paint industries, the raw material in preparation of methanol single cell protein and synthesis of methyl ester. ▼▲ Industry Applications Role/Benefit Laboratory HPLC, UV/VIS spectroscopy, and LCMS Low UV cutoff Chemical manufacture Production of formaldehyde and its derivates Main feedstock Production of hydrocarbon chains and even aromatic systems Main feedstock Production of methyl tert-butyl ether Methylation reagent Production of dimethyl terephthalic acid, methyl methacrylate and acrylic acid methyl ester Main feedstock Plastics Production of polymers Main feedstock Farm chemical Production of insecticide and acaricide Main feedstock Pharmaceuticals Production of sulfonamides, amycin, etc Main feedstock Fuel for vehicles Pure methanol fuel Pure methanol does not produce an opaque cloud of smoke in the event of an accident Methanol gasoline Blended directly into gasoline to produce a high-octane, efficient fuel with lower emissions than conventional gasoline Chemical analysis Determination of boron Analysis agent Determination of trace moisture in alcohols, saturated hydrocarbons, benzene, chloroform, pyridine Analysis agent Others Separation of calcium sulfate and magnesium sulfate Separation reagent Separation of strontium bromide and barium bromide Separation reagent Anti-freezing agent Effective component Methanol has numerous uses. Its main use is in the production of formaldehyde, whichconsumes approximately 40% of methanol supplies. Methanolis a common organic solvent found in many products including deicers (windshield wiperfl uid), antifreezes, correction fl uid, fuel additives, paints, and other coatings. A number ofindustrial chemicals use methanol in their production. Among these are methyl methacrylateand dimethyl terephthalate. Methanol is used to convert methylacrylamide sulfate to methylmethacrylate and ammonium hydrogen sulfate (NH4HSO4):Methanol is used in making the ester dimethyl terephthalate from mixtures ofxylene of toluene. Dimethyl terephthalate is used in the manufacture of polyesters and plastics.Methanol is used as a fuel additive. The common gasoline additive HEET is pure methanoland is used as a gas-line antifreeze and water remover. Methanol is used as a fuel in camp stoves and small heating devices. It is used to fuel the small engines used in models (airplanes,boats). In the early history of automobiles,methanol was a common fuel. The availability of cheap gasoline replaced methanol in the1920s, but it is receiving renewed interest as an alternative fuel as the demand and cost of oilincrease and oil supplies become uncertain. Methanol can be produced from coal and biomass.Methanol has a higher octane rating and generally lower pollutant emissions compared togasoline. The relatively low flame temperature means that fewer nitrogen oxides are producedby methanol than by ethanol. One large disadvantage of methanol is that it has a lower energydensity than gasoline. Using equivalent volumes of gasoline and methanol, methanol givesabout half the mileage of gasoline. Another problem with methanol is its low vapor pressure,resulting in starting problems on cold days. This problem can be mitigated by using a blendof 85% methanol and 15% gasoline. This mixture is called M85 and is similar to E85 ethanol(see Ethyl Alcohol). Methanol is used in the production offormaldehyde, acetic acid, methyl tert-butylether, and many chemical intermediates; asan octane improver (in oxinol); and as apossible alternative to diesel fuel; being anexcellent polar solvent, it is widely used as acommon laboratory chemical and as a methylating reagent. high purity grade for ICP-MS detection Methylalcohol, CH30H, also known as methanol or wood alcohol, is a colorless, toxic, flammable liquid with a boiling point of 64.6 °C(147 °F). The principal toxic effect is on the nervous system,particularly the retinae. Methyl alcoholis miscible in all proportions with water,ethyl alcohol, and ether. It burns with a light blue flame producing water and carbon dioxide. This vapor forms an explosive mixture(6.0 to 36.5% by volume) with air. Methyl alcohol is an important inexpensive raw material that is synthetically produced for the organic chemical industry. Nearly half of the methyl alcohol manufactured is used in the production of formaldehyde. Other uses of methyl alcohol are as an antifreeze and fuel for automobiles and as an intermediate in the production of synthetic protein. Industrial solvent. Raw material for making formaldehyde and methyl esters of organic and inorganic acids. Antifreeze for automotive radiators and air brakes; ingredient of gasoline and diesel oil antifreezes. Octane booster in gasoline. As fuel for picnic stoves and soldering torches. Extractant for animal and vegetable oils. To denature ethanol. Softening agent for pyroxylin plastics. Solvent and solvent adjuvant for polymers. Solvent in the manufacture of cholesterol, streptomycin, vitamins, hormones, and other pharmaceuticals.
  • Description Methyl alcohol, also known as methanol or wood alcohol, is a clear, colorless, flammable liquid that is the simplest alcohol.World production of methanol is approximately 8.5 billion gallons annually. Methanol is produced industrially, starting with the production of synthesis gas or syngas. Syngas used in the production of methyl alcohol is a mixture of carbon monoxide and hydrogen formed when natural gas reacts with steam or oxygen. Methyl alcohol is then synthesized from carbon monoxide and hydrogen.Methyl alcohol is poisonous and is commonly used to denature ethyl alcohol. Methanol poisoning results from ingestion, inhalation of methanol vapors, or absorption through the skin. Methanol is transformed in the body to formaldehyde (H2CO) by the enzyme alcohol dehydrogenase.The formaldehyde is then metabolized to formic acid (HCOOH)by aldehyde dehydrogenase.
  • Physical properties Clear, colorless liquid with a characteristic alcoholic odor. Odor threshold concentrations ranged from 8.5 ppbv (Nagata and Takeuchi, 1990) to 100.0 ppmv (Leonardos et al., 1969). Experimentally determined detection and recognition odor threshold concentrations were 5.5 mg/m3 (4.2 ppmv) and 69 mg/m3 (53 ppmv), respectively (Hellman and Small, 1974).
