ABSTRACT:
Process for preparing a catalyst for the oxidation of methanol to formaldehyde, comprising reacting iron powder and molybdenum trioxide in a Mo/Fe ratio from 1.5 to 5 in an aqueous suspension at temperatures from 20 to 100° C., and subsequently, optionally simultaneously, oxidizing the mixture with an oxidizing agent in a quantity equal to, or greater than the quantity required for the oxidation of the ferrous ion to ferric ion and to oxidize the molybdenum to the valence state 6.
