colorless clear liquid, the vapor and air can form an explosive mixture, when burning to produce a blue flame. The critical temperature was 240.0 ℃; The critical pressure was 78. 5atm. With water, ethanol, ether, benzene, ketones and other organic solvents miscible. Its vapor and air to form an explosive mixture, fire, high heat caused by combustion explosion. A strong reaction with an oxidizing agent can occur. In case of high fever, the internal pressure of the container increases, and there is a risk of cracking and explosion. There is no flame when burning. Can accumulate static electricity, ignition its vapor.
The water content of industrial methanol was reduced to less than 01% by distillation. The Acetone can be removed by further treatment with Sodium periodate. Pure methanol was obtained by distillation.
standards for chromatographic analysis and solvents for instrumental analysis.

Has a stimulating effect on the respiratory tract and gastrointestinal mucosa, toxic effects on blood vessels and nerves, causing vasospasm, the formation of blood stasis or bleeding; Has a special selective effect on the optic nerve and retina, necrosis of the retina due to lack of nutrition. Store in a cool, ventilated warehouse. Keep away from fire and heat source. The bin temperature should not exceed 30 ℃. Protection from direct sunlight. Keep the container sealed. Should be stored separately from the oxidant.
