An industrial method for preparation of methanol is:

A

Catalytic reduction of carbon monoxide in presence of `ZnO-Cr_(2)O_(3)`

B

Reacting methane with stem at `900^(@)C` with a nickel catalyst

C

Reducing formaldehlyde with `LiAIH_(4)`

D

Text Solution

Verified by Experts

Industrially, syn-gas is used to prepare methanol employing a ZnO catalyst and a `Cr_(2)O_(3)` promoter. Methanol, which is also called wood spirit is used to denature ethanol during its production along with pyridine. The process is
`CO+2H_(2)overset(ZnO-Cr_(2)O_(3))rarr underset("methanol")(CH_(3)OH)`
