Industrial Methanol
Industrial Methanol is mainly used to manufacture a variety of organic products such as olefins, formaldehyde, acetic acid, methylamine, dimethyl sulfate, and methyl chloride. Because of its good flammability, it can be infiltrated into gasoline as a solvent and can also be used as fuel.

Description
It is liquid at room temperature and is a neutral liquid. Under normal conditions, it is colorless and transparent, easily soluble, volatile, and flammable. It is a toxic liquid with a slightly similar smell to ethanol. Methanol is infinitely miscible with water and many organic liquids such as ethanol and ether, but it is not miscible with aliphatic hydrocarbons. It is the saturated monohydric alcohol with the simplest molecular structure and one of the basic organic raw materials. It is mainly used to manufacture a variety of organic products such as olefins, formaldehyde, acetic acid, methylamine, dimethyl sulfate, and methyl chloride. Because of its good flammability, it can be infiltrated into gasoline as a solvent and can also be used as fuel.
We are the first drafting unit of the national standard for industrial methanol GB 338-2011.
