The main uses of methanol
1, Chemical raw material field
Production of formaldehyde: used in the manufacture of adhesives, coatings, plastics (such as artificial boards), and wood processing;
Synthetic acetic acid: used as a food acidity regulator, pharmaceutical intermediate, and textile raw material;
Preparation of methyl tert butyl ether (MTBE): used as an anti knock additive in gasoline to increase octane value;
Production of organic compounds such as chloromethane and methyl acrylate: used for manufacturing pesticides (such as methyl parathion), pharmaceuticals, and synthetic fibers;
Manufacturing methyl formate and dimethyl carbonate: used in insecticides, fuel additives, and chemical intermediates.
2, Energy sector
Direct use of fuel: replacing or blending gasoline as a vehicle fuel, with clean and efficient characteristics;
Production of dimethyl ether (DME): used as a substitute for liquefied petroleum gas for civilian fuel;
Hydrogen production carrier: providing hydrogen gas for fuel cells through reforming reactions;
Power generation and agricultural machinery fuel: used for generator sets, greenhouse heating, and agricultural machinery power.
3, Solvent and Industrial Applications
Organic solvents: used for dissolving and cleaning in the production of paints, inks, rubber, and pharmaceuticals;
Electronic industry cleaning agents: cleaning precision components such as semiconductors and photovoltaic modules;
Protein precipitation and purification: used for nucleic acid extraction and protein processing in in vitro diagnostic reagents.
4, Agriculture and medicine fields
Pesticide raw materials: synthetic insecticides and fungicides such as carbendazim;
Plant growth promoters: improve crop stress resistance and reduce irrigation demand;
Pharmaceutical intermediates: involved in the synthesis of sulfonamide drugs and antibiotics.
5, Other uses
Antifreeze and Denaturator: Used in industrial and automotive antifreeze, or as an ethanol denaturing agent;
Feed additive: Methanol protein is produced through fermentation for animal feed.
