UNSUPPORTED CATALYST FOR THE OXIDATION OF METHANOL TO FORMALDEHYDE

摘要

This invention relates to an improved oxidation catalyst for the production of formaldehyde from methanol. Said improvement consists of finely grinding and balling an iron oxide-molybdenum oxide catalyst precursor into roughly spherical agglomerates while simultaneously applying an aqueous solution of ammonium hepta-molybdate and ammonium 6-molybdocobaltate (III) prior to dehydration and activation.
