What is CH3OH? Important knowledge about CH3OH

1. Definition of CH₃OH

CH₃OH is also known as methanol, commonly referred to as methyl alcohol or wood alcohol. In English, it is called “Methanol”. CH₃OH has a molar mass of 32.04 g/mol. The molecular structure includes one carbon atom, three hydrogen atoms, one oxygen atom and another hydrogen atom. CH₃OH does not form ions in its natural state.

2. Properties: CH₃OH

2.1 Physical properties of CH₃OH

Methanol is a transparent liquid, colorless, with a very slight and distinctive smell. The pH of methanol is approximately 7, making it a neutral substance.

2.2 Chemical properties of CH₃OH

Methanol can react with metals, acids, non-metals, and salts. It can be easily oxidized to formaldehyde, and then to formic acid.

3. Common chemical equations for CH₃OH

Metal reaction: CH₃OH + Na-� -> �� CH₃ONa + H₂ ->
Acid reaction: CH₃OH + H₂SO₄-� -> �� CH₂=O + H₂O + SO₂ ->

4. Synthesis of CH₃OH

4.1 Laboratory synthesis of CH₃OH

CH₃OH is not commonly synthesized in the laboratory as this process requires high temperature and pressure conditions.

4.2 Industrial synthesis of CH₃OH

In the industry, CH₃OH is synthesized by working with natural gas under high temperature and pressure conditions.
