Chemical Properties

NIST Information Methyl alcohol (67-56-1)
EPA Chemical Substance Information Methanol (67-56-1)

Flammable Vapor and air can form explosive mixtures case of fire, high-heat combustion caused the explosion. Chemically react with the oxidant or cause a fire. In the scene, heating containers risk of explosion. Can spread to the lower Department of considerable far away and met the fire will generate a return to burning. burning and decomposition of carbon monoxide, carbon dioxide and water. There are highly toxic. 
application 
1. One of the basic organic raw material mainly used in the manufacture Formaldehyde, acetic acid, methyl chloride, methyl amine and dimethyl sulfate and other organic products. 
2. One of the important chemical raw materials in recent years, with the development of C1 chemical, methanol has become an important raw material for the production of ethylene and propylene. 
3. used as solvent paints, varnishes, shellac, ink, adhesives, dyes, alkaloids, cellulose acetate, cellulose nitrate, ethyl cellulose, polyvinyl butyral and the like. 
4. is the manufacture of pesticides, pharmaceuticals, plastics, synthetic fibers and organic chemical products such Formaldehyde, methylamine, methyl chloride, dimethyl sulfate and other raw materials. Other used automotive antifreeze, metal surface cleaning agents and alcohol denaturation agent. 
5. It is important fuel, can be incorporated into gasoline as alternative fuel use since the 1980s, for the production of methanol, gasoline octane additive methyl tert-butyl ether, methanol, gasoline, methanol fuel and methanol protein and other products, greatly promoted the development of methanol production and market needs; methanol has been used as a fuel additive F1 car use, but also widely used in methanol fuel cells. 
6. reagents for the analysis, such as solvent, methylation reagents, chromatography reagents are also used in organic synthesis. 
7. methanol as cleaning degreaser, MOS level is mainly used for discrete devices, in LSI, BV-Ⅲ grade is mainly used in VLSI technology
