Methanol 99.5% AR [67-56-1]
Methanol is produced industrially, starting with the production of syngas or syngas. The synthesis gas used in the production of methyl alcohol is a mixture of carbon monoxide and hydrogen formed when natural gas reacts with steam or oxygen. The methyl alcohol is then synthesized from carbon monoxide and hydrogen.
