Abstract: A process for preparing formaldehyde by gas-phase oxidation of methanol vapor by means of a gas stream comprising molecular oxygen in the presence of a fixed-bed catalyst comprising iron and molybdenum, wherein the process is carried out in a reactor ( 1 ) having heat-exchange plates ( 2 ) which are arranged in the longitudinal direction of the reactor ( 1 ) and have a spacing between them and through which a heat transfer medium flows, inlet and outlet facilities ( 3, 4 ) for the heat transfer medium to the heat-exchange plates ( 2 ) and also gaps ( 5 ) between heat-exchange plates ( 2 ) in which the fixed-bed catalyst is present and into which the methanol vapor and the gas stream comprising molecular oxygen are passed, is described.
