Almost exactly the same as methanol, so refined methanol should really be a refined product of methanol.

Chemical molecular formula of refined methanol: CH3OH, colorless, clear and volatile liquid, soluble in water, alcohol and ether, flammable, narcotic, toxic and harmful to eyes. In severe cases, it will lead to blindness. The allowable concentration in the air is 50 mg/m3, and there is no flame when burning. Its vapor and air form an explosive mixture, which is in danger of burning and explosion when exposed to open flame, high temperature and oxidant. 2. Relative density: 0.79 1 1(20℃)g/cm3 Boiling point: 64.8℃ Freezing point: -97.8℃ Explosion limit: 6.7-36%(V) Flash point:1/. Widely used in chemical industry, medicine, light industry, textile, transportation and other industries. Mainly used in the manufacture of formaldehyde, acetic acid, methyl chloride, methylamine, dimethyl sulfate and other organic products. It is also one of the important raw materials for pesticides and medicine. Refined methanol can also be used as fuel instead of gasoline. Methanol is the main component of fake wine. Refined methanol is also called wood alcohol or wood alcohol. The lowest dose of human oral poisoning is about 0.lg/Kg,, and 0.3 ~1g can cause death. The new energy of refined methanol is mainly manifested in: methanol gasoline is used as automobile fuel, because general gasoline comes from crude oil; Methanol can come from coal, natural gas, coke oven gas, coalbed methane, coal chemical enterprises and inferior coal resources with high sulfur and ash. Therefore, it can be said to be a new source of automobile fuel for countries that lack crude oil and oil and gas but are rich in coal. Molecular formula: CH3OH, molecular weight 32.04, colorless, transparent and volatile liquid, with a smell similar to ethanol. Refined methanol is one of the most commonly used organic solvents. Soluble in water, reduced in volume, miscible with various organic solvents such as ethanol and acetic acid. Refined methanol is a toxic chemical product. It has a significant anesthetic effect and is the most harmful to the optic nerve. When inhaling concentrated refined methanol vapor, it will cause poisoning, headache, nausea, vomiting, tears, blurred vision and eye pain. It will take several days to recover. The allowable concentration in air is 0.05mg/l, and the allowable concentration limit in air is 2000ppm. Refined methanol is widely used in industry. Besides being a good solvent for many organic substances, it is mainly used in industrial production, such as synthetic fibers, formaldehyde, plastics, medicines, pesticides, dyes and synthetic protein. It is a basic organic chemical raw material. Refined methanol and gasoline (diesel oil) or other substances can be mixed into various new industrial or civil fuels, and the mixture of refined methanol and gasoline can be used as transportation fuel.
