Product Description:
Methanol, also known as hydroxymethane, is an organic compound and the simplest saturated mono alcohol in structure. Its chemical formula is CH3OH/CH₄O, of which CH₃OH is the structural short form, which can highlight the hydroxyl group of methano. Because it was first found in the dry distillation of wood, it is also known as & ldquo; wood alcohol & rdquo; or & ldquo; wood spirit & rdquo;. The lowest dose of human oral poisoning is about 100mg/kg body weight, oral intake of 0.3 ~ 1g/kg can be fatal. Used in the manufacture of formaldehyde and pesticides, etc., and used as an extractant of organic matter and alcohol denaturant, etc.. Finished products are usually produced by reacting carbon monoxide with hydrogen.
Product Properties and Stability:
Colorless clear liquid, its vapour and air can form explosive mixtures, when burned to produce blue flame. Critical temperature 240.0°C; critical pressure 78.5atm, miscible with water, ethanol, ether, benzene, ketones and other organic solvents. Its vapour forms explosive mixture with air, which can cause combustion and explosion when exposed to open fire and high heat. It can react strongly with oxidant. If it meets high heat, the pressure inside the container increases, and there is a danger of cracking and explosion. No light flame when burning. Can accumulate static electricity and ignite its vapour.
Product Application:
1.One of the basic organic raw materials, used in the manufacture of chloromethane, methylamine and dimethyl sulphate and many other organic products. It is also a raw material for pesticides (insecticides, acaricides), medicines (sulfonamides, hapten, etc.), and one of the raw materials for the synthesis of dimethyl terephthalate, methyl methacrylate and methyl acrylate.
2.The main application of methanol is the production of formaldehyde.
3.Another major use of methanol is the production of acetic acid. It can produce vinyl acetate, acetate fibre and acetate, etc. Its demand is closely related to that of paints, adhesives and textiles.
4.Methanol can be used to manufacture methyl formate.
5.Methanol can also manufacture methylamine, methylamine is an important fatty amine, with liquid nitrogen and methanol as raw materials, can be discrete through processing for a methylamine, dimethylamine, trimethylamine, is one of the basic chemical raw materials.
6.It can be synthesised into dimethyl carbonate, which is an environmentally friendly product and used in medicine, agriculture and special industries, etc.
7.It can be synthesised into ethylene glycol, which is one of the petrochemical intermediate raw materials and can be used in the production of polyester and antifreeze.
8.It can be used in the manufacture of growth promoter, which is beneficial to the growth of dryland crops.
9.Also can be synthesised methanol protein, methanol as raw material produced by microbial fermentation of methanol protein is known as the second generation of single-cell proteins, compared with natural proteins, nutritional value is higher, the crude protein content is much higher than that of fishmeal and soya beans, and is rich in amino acids, minerals and vitamins, which can be used in place of fishmeal, soya beans, bone meal, meat and skimmed milk powder.
10.Methanol is used as cleaning and degreasing agent.
11.Used as an analytical reagent, such as solvents, methylation reagents, chromatographic reagents. Also used in organic synthesis.
12.Usually methanol is a better solvent than ethanol, can dissolve many inorganic salts. Can also be blended into gasoline as an alternative fuel. Methanol is used in the production of gasoline octane additive methyl tertiary butyl ether, methanol gasoline, methanol fuel, and methanol protein and other products.
13.Methanol is not only an important chemical raw material, but also an energy source and vehicle fuel with excellent performance. Methanol reacts with isobutylene to obtain MTBE (methyl tertiary butyl ether), which is a high-octane unleaded gasoline additive and can also be used as a solvent. In addition, it can also be used to produce olefins and propylene.
14.Methanol can be used to produce dimethyl ether. The new liquid fuel made of methanol and dimethyl ether formulated in a certain proportion is called alcohol ether fuel. Its combustion efficiency and thermal efficiency are higher than that of liquefied gas.
Product Storage Notes:
1.Store in a cool, ventilated warehouse.
2.Keep away from fire and heat source.
3.Keep the container sealed.
4.It should be stored separately from water, ethanol, ether, benzene, ketones, and should never be mixed.
5.Prohibit the use of mechanical equipment and tools that are easy to generate sparks.
The storage area should be equipped with leakage emergency treatment equipment and suitable shelter materials.
