Summary: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. L'invention porte sur un procédé de préparation d'un catalyseur pour l'oxydation du méthanol en formaldéhyde comprenant la mise en réaction de poudre de fer et de trioxyde de molybdène selon un rapport Mo/Fe de 1,5 pour 5 dans une suspension aqueuse à des températures de 20 à 100 degrés Celcius et, subséquemment, éventuellement simultanément, l'oxydation du mélange au moyen d'un agent oxydant selon une quantité égale ou supérieure à la quantité requise pour l'oxydation de l'ion ferreux en un ion ferrique et pour oxyder le molybdène en un état de valence 6.
