methanol, chemical formula CH3OH (molecular formula CH4O), is a colorless, volatile, flammable transparent liquid, with a weak smell of alcohol, melting point -97.6 ℃, boiling point 64.7 ℃, molecular weight 32.04, density 0.7918 g/cm & sup3;. It is the simplest aliphatic alcohol and one of the most important basic chemical raw materials. It is widely used in the synthesis of formaldehyde, MTBE, acetic acid, dimethyl ether, biodiesel and methyl chloride. Methanol can be miscible with water and most organic solvents in any proportion, and can react with a variety of compounds to generate a variety of derivatives, which are of great value in chemical production. In the chemical fiber industry, methanol is used as a raw material; in the plastics industry, it is involved in the production of resins and plasticizers; in the pharmaceutical and pesticide industries, methanol is used as a solvent and intermediate; in addition, methanol is also used to produce clean fuels and biodiesel. As a bulk platform chemical, methanol has an irreplaceable position in modern industrial production.
methanol is an important organic chemical raw material. It can be used to produce formaldehyde (the largest downstream product), methyl tert-butyl ether (MTBE), acetic acid, dimethyl ether (DME), biodiesel, methyl chloride and methylamine and other chemical products and intermediates. It has important uses in chemical raw materials, synthetic resins, synthetic fibers, plastics, synthetic rubber, medicine, pesticides, spices, dyes, coatings and oil refining industries. In addition, methanol can also be used as a clean fuel, solvent and antifreeze, as a raw material for the production of olefins (MTO/MTP process), methanol can be converted into ethylene and propylene, extending its value to the petrochemical industry chain. As the demand for new energy materials grows, methanol is increasingly used in direct methanol fuel cells (DMFCs) and as a hydrogen carrier.
