FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a catalyst for oxidising methanol to formaldehyde and can be used in production of formaldehyde and urea-formaldehyde resin. The method of producing a catalyst for oxidising methanol to formaldehyde involves reaction of an iron-containing component with molybdenum trioxide with subsequent moulding of granules, drying and calcination, wherein the iron-containing component used is iron oxide, and the reaction is carried out in a mill with impact-shear action and power density 10-200 W/g and weight ratio MoO3:Fe2O3=(80-40):(20-60).
EFFECT: use of the invention increases specific surface area by 51-84%, mechanical strength by 60-68%, and cuts the number of process operations twofold.
