Uses: 1. Methanol is widely used, being basic organic chemical raw materials and high-quality fuel. It is mainly used in fine chemicals, plastics and other fields to manufacture formaldehyde, acetic acid, methyl chloride, methylamine, dimethyl sulfate and other organic products, being the raw materials of pesticides and pharmaceuticals. Methanol, after the deep processing, can be used as a new type of clean fuel and can also be added to the gasoline for blending.
2. Methanol oxidation of formaldehyde
3. Methanol, at high temperature, the presence of pumice silver, catalyst or other solid catalyst, can be subject to direct oxidation into formaldehyde. At present, more than 40% of methanol at home and abroad is used for the production of formaldehyde, further for production of synthetic resins, plastics and other chemical raw materials. POM is an excellent-performance engineering plastics with very extensive applications. Formaldehyde is also used to make butanediol, urotropine, nearly 100 kinds of downstream products.
4. Manufacturing of methylamine from methanol amination
5. Methanol is mixed with ammonia in a certain proportion. Under the pressure of 370-420 DEG C and 5.0-20.0MPa, use activated alumina as a catalyst to obtain a mixture of monomethylamine, dimethylamine and trimethylamine, followed by distillation to obtain mono, di or trimethylamine products. Mono-, di-, and tri-methylamine can be applied to the fields of pesticides, pharmaceuticals and dyes or used as organic raw materials intermediates.
6. Methanol, under the presence of metal silicoaluminium catalyst or ZSM-5 type molecular sieve, can be used to make dimethyl ether through dehydration.
7. Dehydrogenation of Methanol can lead to Methyl Formate.
8. Methyl formate is a raw material of organic synthesis and can be used for making formamide, dimethyl formamide. Formamide is the raw material of medicine, spices and dyes and can also be used as paper processing agent, the softener of the fiber industry and the polar solvents of organic synthesis. Dimethylformamide is an important organic chemical raw material and excellent solvent, can be used as gas absorbers and applied to fields of pesticides, synthetic leather, polyacrylonitrile spinning and butadiene extraction.
9.    Extraction solvent; the maximum allowable residue of the finished product: spice oil resin 50mg/kg; hops extract 2.2mg/kg.
10. GB 2760-96 lists it as a food processing aids.
11. It is used as analysis reagent and chromatography reagent as well as for organic synthesis
12. It is mainly used in the preparation of formaldehyde and as a methylating agent and solvent in organic synthesis, being the raw material of methyl tert-butyl ether. It can also be used as automotive fuel
13. It can be used for the separation of calcium sulfate and magnesium sulfate, separation of strontium bromide and barium bromide and determination of boron reagent.
14. It is one of the basic organic raw materials. Mainly used in the manufacture of formaldehyde, acetic acid, methyl chloride, methylamine and dimethyl sulfate and other organic products. It is also one of the raw materials of pesticides (pesticides, acaricide), medicine (sulfonamides, heminomycin, etc.), Synthesis of dimethyl terephthalate, methyl methacrylate and methyl acrylate. It is also an important solvent and can also be mixed with gasoline as an alternative fuel for application. Since the 1980s, methanol has been used to produce gasoline octane value additives methyl tert-butyl ether, methanol gasoline, methanol fuel, and methanol protein products, greatly promoting the development of methanol production and market demands.
15. It can be used as basic organic raw materials, solvents and antifreeze agent. Mainly used for formaldehyde, flavor, dyes, medicine, gunpowder, antifreeze and so on.
16. It can be used for the preparation of Karl Fischer reagent to determine the trace amount of water contained in the alcohol, saturated hydrocarbons, benzene, chloroform and pyridine.
