Abstract: A process for the catalytic gas-phase oxidation of propene to acrolein in a multiple contact tube fixed-bed reactor, with only one heat transfer medium being circulated through the space surrounding the contact tubes, at elevated temperature over catalytically active multimetal oxides at a propene conversion on a single pass of >/= 90 mol% and a selectivity of acrolein formation of >/= 85 mol%, in which the heat exchange medium on the one hand is passed longitudinally, viewed over the reaction vessel, to the contact tubes in cocurrent to the reaction gas mixture through the multiple contact tube fixed-bed reactor and, on the other hand, has, within the reaction vessel, due to a successive arrangement, along the contact tubes, of deflecting discs which leave open cross-sections free, a superposed crossflow in such a way that, in longitudinal section through the contact tube bundle, a meander-like flow of the heat exchange medium results and the flow velocity of the circulated heat exchange medium is here set in such a way that the temperature of the heat exchange medium rises by from 2 to 10 DEG C from the inlet point to the reactor to the outlet point from the reactor.
