nature
A colorless, clear liquid whose vapor and air can form an explosive mixture that produces a blue flame when burned. Critical temperature 240.0ºC; Critical pressure 78.5 ATM. It can be miscible with water, ethanol, ether, benzene, ketone and other organic solvents. Its vapor and air form an explosive mixture, which causes combustion and explosion in case of open fire and high heat energy. Can react strongly with oxidizing agents. In case of high heat, the pressure inside the container increases, and there is a risk of cracking and explosion. No flame when burning. It builds up static electricity and ignites its vapor.
preparation
The water content of industrial methanol was reduced to 0.01% by distillation. The acetone can be removed by treatment with sodium hypoiodate. Purified methanol was obtained by distillation.
use
Chromatographic standards and solvents for instrumental analysis.
Methanol is widely used as a basic organic chemical raw material and high quality fuel. Mainly used in fine chemicals, plastics and other fields, used to produce formaldehyde, acetic acid, chloromethane, methylamine, dimethyl sulfide and other organic products, is also one of the important raw materials of pesticides, medicine. Methanol can be used as a new type of clean fuel after deep processing, and it can also be mixed with gasoline. Methanol reacts with ammonia to produce monomethylamine.
