Methanol is an important industrial chemical.
Commercially, methanol is produced from synthesis gas.
Synthesis gas is mainly a mixture of:
\[
CO
\]
and:
\[
H_2.
\]
The main reaction for methanol production is:
\[
CO+2H_2\rightarrow CH_3OH.
\]
Sometimes carbon dioxide also participates:
\[
CO_2+3H_2\rightarrow CH_3OH+H_2O.
\]
Formaldehyde and acetic acid are products that may be made from methanol or related processes.
Ethanol is a different alcohol and is not the key raw material for methanol production.
Therefore, the key raw material for commercial production of methanol is:
\[
\text{Synthesis gas}.
