Methanol Oxidation to Formaldehyde

2CH₃OH + O₂ → 2HCHO + 2H₂O

نظرة عامة

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.

مثال من الحياة اليومية

Formaldehyde is used in particleboard and MDF manufacturing, and its solutions (formalin) were historically used to preserve biological specimens.

الأهمية الصناعية

Over 50 million tonnes of formaldehyde are produced annually for resins (urea-formaldehyde, phenol-formaldehyde), plastics, and as a chemical intermediate.
