Abstract

Procedure for obtaining formaldehyde by oxidative dehydrogenation of methanol in the presence of a silver catalyst at elevated temperature, characterized in that a part of the exhaust gas obtained after the reaction and the separation of the main quantity of formaldehyde is treated with an amount of 1 to 2 mol, based on 1 mol of methanol fed to the reaction, of a basic compound and/or oxidation agent and recycled back to the reaction.
