Methanol Oxidation to Formaldehyde

2CH3OH + O2 → 2HCHO + 2H2O

Обзор

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.

Пример из жизни

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

Промышленное значение

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