One of the basic organic raw materials, used to make various organic products such as methyl chloride, methylamine and dimethyl sulfate. It is also the raw material of pesticides (pesticides, acaricides) and drugs (sulfonamides, synthetic mycin, etc.). ) is also one of the raw materials for synthesizing dimethyl terephthalate, methyl methacrylate and methyl acrylate.
The main application field of methanol is the production of formaldehyde, which can be used to produce adhesives, mainly used in wood processing industry, and secondly used as a treatment agent for molding plastics, coatings, textiles and paper.
Another main use of methanol is to produce acetic acid. The consumption of acetic acid accounts for about 7% of the global demand for methanol, which can produce vinyl acetate, cellulose acetate and acetate. Its demand is closely related to the demand of coatings, adhesives and textiles.
Methanol can be used to produce methyl formate, which can be used to produce fine chemical products such as formic acid and formamide, and can also be used as pesticides, fungicides, fumigants, tobacco treatment agents and gasoline additives.
Methylamine can also be made from methanol. Methylamine is an important fatty amine, which can be separated into monomethylamine, dimethylamine and trimethylamine from liquid nitrogen and methanol, and is one of the basic chemical raw materials.
Dimethyl carbonate can be synthesized, which is an environmentally-friendly product and applied to medicine, agriculture and special industries.
Ethylene glycol can be synthesized, which is one of petrochemical intermediates and can be used to produce polyester and antifreeze.
Can be used for manufacturing growth promoters. It can greatly increase crop yield, keep branches and leaves fresh and vigorous, and will not wither in summer, which can greatly reduce irrigation water and is beneficial to the growth of dry land crops.
Methanol protein can be synthesized. Methanol protein produced by microbial fermentation with methanol as raw material is called the second generation single cell protein. Compared with natural protein, it has higher nutritional value, crude protein content is much higher than that of fish meal and soybean, and it is rich in amino acids, minerals and vitamins, which can replace fish meal, soybean, bone meal, meat and skim milk powder.
Methanol is used as cleaning degreaser, MOS grade is mainly used for discrete devices and medium and large scale integrated circuits, and BV-III grade is mainly used for VLSI process.
Used as analytical reagents, such as solvents, methylation reagents and chromatographic analysis reagents. It is also used in organic synthesis.
Generally speaking, methanol is a better solvent than ethanol and can dissolve many inorganic salts. It can also be mixed with gasoline as an alternative fuel. Since 1980s, methanol has been used to produce gasoline octane number additives such as methyl tert-butyl ether, methanol gasoline, methanol fuel and methanol protein, which has promoted the development of methanol production and market demand.
Methanol is not only an important chemical raw material, but also an excellent energy source and vehicle fuel. MTBE (methyl tert-butyl ether) is obtained by the reaction of methanol and isobutylene, which is a high octane number unleaded gasoline additive and can also be used as a solvent. In addition, olefin and propylene can be produced to solve the problem of resource shortage.
Methanol can be used to produce dimethyl ether, which is not only widely used in daily chemicals, medicine, pesticides, dyes, coatings and so on. But also has the advantages of convenient cleaning, high cetane number, good dynamic performance and less pollution. Fuel characteristics, such as easy to pressurize into liquid and easy to store. A new liquid fuel made of methanol and dimethyl ether in a certain proportion is called alcohol ether fuel. Its combustion efficiency and thermal efficiency are higher than that of liquefied gas.
