Methanol Oxidation to Formaldehyde

2CH₃OH + O₂ → 2HCHO + 2H₂O

Genel Bakış

Methanol is oxidized to formaldehyde by oxygen over a metal oxide catalyst. The carbon oxidation state changes from -2 in methanol to 0 in formaldehyde. This catalytic partial oxidation is the primary industrial route to formaldehyde, the simplest aldehyde.
