Methanol is the simplest aliphatic alcohol. It is a colorless, flammable, irritating liquid with a boiling point of 64.7°C, a melting point of -93.90°C, and a relative density of 0.7913. It is miscible with water and most organic solvents. It is highly toxic and may cause damage to the optic nerve. Ingestion can lead to blindness and even fatal poisoning.
Methanol carries the typical chemical characteristics of primary aliphatic alcohol. The three hydrogen atoms on the carbon linked to the hydroxyl group can undergo sequential oxidation to produce formaldehyde, formic acid and carbon dioxide. For this reason, it is widely consumed for formaldehyde synthesis. Methanol can be readily converted into key organic intermediates including methyl carboxylate, methyl chloride and methylamine. It also serves as an essential organic solvent, extracting agent and alcohol denaturant.
