1, one of the basic organic raw materials, used for the manufacture of methane chloride, methylamine and dimethyl sulfate and other organic products. It is also the raw material of pesticide (insecticide, acaricide), medicine (sulfonamides, comycin, etc.), and one of the raw materials for the synthesis of dimethyl terephthalate, methyl methacrylate and methyl acrylate. [5]
2, the main application field of methanol is the production of formaldehyde, formaldehyde can be used to produce adhesives, mainly used in wood processing industry, followed by used as a treatment agent for molding plastics, coatings, textiles and paper.
3. Another major use of methanol is the production of acetic acid. Acetic acid consumption accounts for about 7% of global methanol demand, which can be used to produce vinyl acetate, fibre acetate and acetate, and its demand is closely linked to the demand for coatings, adhesives and textiles.
4. Methanol can be used to produce methyl formate, which can be used to produce formic acid, formamide and other fine chemical products. It can also be used as insecticide, fungicide, fumigant, tobacco treatment agent and gasoline additive.
5, methanol can also produce methylamine, methylamine is an important fatty amine, with liquid nitrogen and methanol as raw materials, can be separated into a methylamine, dimethylamine, trimethylamine through processing, is one of the basic chemical raw materials.
6, can be synthesized into dimethyl carbonate, is a kind of environmental protection products, used in medicine, agriculture and special industries.
7, can be synthesized into glycol, is one of the petrochemical intermediate raw materials, can be used to produce polyester and antifreeze.
8, can be used to manufacture growth promoter. It can greatly increase crop yield, keep the branches and leaves fresh, strong and lush, will not wither in summer, can greatly reduce irrigation water, conducive to the growth of dryland crops.
9, can synthesize methanol protein, methanol as raw materials by microbial fermentation to produce methanol protein known as the second generation of single cell protein, compared with the natural protein, nutritional value higher, crude protein content is much higher than the fish meal and soybean, and contains rich amino acids, minerals and vitamins, can replace fish meal, soybean, bone meal, meat and skimmed milk powder. [6]
10. Methanol is used as a cleaning agent, MOS grade is mainly used for discrete devices, medium and large-scale integrated circuits, and BV-ⅲgrade is mainly used for very large scale integrated circuit technology.
11, used as analytical reagent, such as solvent, methylation reagent, chromatographic analysis reagent. It is also used in organic synthesis.
12. Methanol is usually a better solvent than ethanol and can dissolve many inorganic salts. It can also be blended with gasoline as an alternative fuel. Since the 1980s, methanol has been used in the production of gasoline octane additive methyl tert-butyl ether, methanol gasoline, methanol fuel, methanol protein and other products, promoting the development of methanol production and market demand.
13. Methanol is not only an important chemical raw material, but also an excellent energy and vehicle fuel. Methanol reacts with isobutene to give MTBE, which is a high octane unleaded gasoline additive and can also be used as a solvent. In addition, alkene and propylene can be produced to solve the problem of resource shortage.
14, methanol can be used to produce dimethyl ether, dimethyl ether in addition to daily chemicals, pharmaceuticals, pesticides, dyes, coatings and other aspects have a wide range of uses, but also has convenient cleaning, cetane value, good dynamic performance, less pollution. Easy to pressure into liquid, easy to store and other fuel properties. A new type of liquid fuel is called alcohol ether fuel which is prepared by methanol and dimethyl ether in a certain proportion. Its combustion efficiency and thermal efficiency are higher than that of liquefied gas.
Methanol is well known for its toxicity. Industrial alcohol contains about 4% methanol. If it is used by illegal elements as edible alcohol to make fake wine, it will produce methanol poisoning after drinking. The lethal dose of methanol is about 70ml.
Storage Precautions
Store in a cool, well-ventilated warehouse room, away from fire, heat source. Store temperature should not exceed 37℃, keep container sealed. Should be stored separately with oxidizer, acid, alkali metal, etc., do not mix storage. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that may cause sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials.
Transportation Precautions
The railway transportation time limit of this product using steel enterprises provided tank truck shipment, shipment before the approval of the relevant departments. Transportation vehicles should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. It is best to ship in the morning and evening in summer. The trough (tank) car used in transportation should have a grounding chain, and the groove can be equipped with a hole partition to reduce the shock generated static electricity. It is forbidden to mix with oxidizer, acid, alkali metal and edible chemicals. During transportation, it should be protected from sun exposure, rain and high temperature. Stay away from fire, heat source, high temperature area. The exhaust pipe of the vehicle carrying the goods must be equipped with fire retardant device. Mechanical equipment and tools that are easy to generate sparks are prohibited to be loaded and unloaded. Road transportation should follow the prescribed route, do not stay in residential and densely populated areas. Slip away should be forbidden in railway transportation. It is strictly prohibited to transport in bulk by wooden vessel or cement vessel.
