Methyl Alcohol,other name Methanol, also known as hydroxymethane, is an organic compound that is toxic. It is the simplest saturated monohydric alcohol. Its chemical formula is CH3OH/CH4O, of which CH3OH is a simplified structural formula, which can highlight the hydroxyl group of methanol. The CAS number is 67-56-1, the molecular weight is 32.04, and the boiling point is 64.7 °C. Because it was first discovered in dry distillation wood, it is also called "wood alcohol" or "wood essence". The lowest dose of human oral poisoning is about 100mg/kg body weight, and oral intake of 0.3 to 1g/kg can cause death. It is used in the manufacture of formaldehyde and pesticides, and as an extractant for organic matter and a denaturant for alcohol. Finished products are usually made by reacting carbon monoxide with hydrogen.
Methanol is widely used, it's a basic organic chemical raw material and high-quality fuel.Mainly used in fine chemicals, plastics, and also other fields. It can be used to synthesis many organic products, such as formaldehyde, acetic acid, methyl chloride, methyl ammonia, sulfuric acid dimethyl ester and so on, it is also one of the important raw materials for pesticides and medicines. It can be used as a new type of clean fuel after deep processing, usually also added to gasoline in combination.
