A PROCESS IS PROPOSED FOR PARTIAL OXIDATION IN THE GAS PHASE OF C3 AND/OR C4 PRECURSOR COMPOUNDS TO (METH) ACROLEIN AND/OR (METH) ACRYLIC ACID IN THE PRESENCE OF A HETEROGENEOUS PARTICULATE CATALYST IN A REACTOR HAVING - ONE OR MORE CUBOIDAL THERMOPLATE MODULES (1) WHICH ARE EACH FORMED FROM TWO OR MORE RECTANGULAR THERMOPLATES (2) ARRANGED PARALLEL TO EACH OTHER WHILE IN EACH CASE LEAVING A GAP (3) WHICH CAN BE FILLED WITH THE HETEROGENOUS PARTICULATE CATALYST AND IS FLOWED THROUGH BY THE FLUID REACTION MIXTURE; THE HEAT OF REACTION BEING ABSORBED BY A HEAT CARRIER WHICH FLOWS THROUGH THE THERMOPLATES (2) AND THUS AT LEAST PARTLY EVAPORATING, AND ALSO HAVING- A PREDOMINANTLY CYLINDRICAL SHELL (4,15,16) WHICH RELEASES THE PRESSURE AT THE THERMOPLATE MODULES, COMPLETELY SURROUNDS THEM AND COMPRISES A CYLINDER JACKET (4) AND HOODS (15,16) WHICHS EAL IT AT BOTH ENDS AND WHOSE LONGITUDINAL AXIS IS ALIGNED PARALLEL TO THE PLANE OF THE THERMOPLATES (2), AND ALSO HAVING - ONE OR MORE SEALING ELEMENTS (7,23) WHICH ARE ARRANGED IN SUCH A WAY THAT THE FLUID REACTION MIXTURE, APART FROM FLOWING THROUGH THE REACTOR INTERIOR SPACES BOUNDED BY THE HOODS (15,16) , ONLY FLOWS THROUGH THE GAP (3).FIGURE 1
