Zusammenfassung:IN A PROCESS FOR PARTIALLY OXIDIZING ACROLEIN TO ACRYLIC ACID IN THE GAS PHASE UNDER HETEROGENEOUS CATALYSIS, THE STARTING REACTION GAS MIXTURE IS OXIDIZED AT AN ACROLEIN LOADING OF 70 I (STP) OF ACROLEIN/I OF FIXED CATALYST BED. H OVER A FIXED CATALYST BED WHICH IS ACCOMMODATED IN TWO SUCCESSIVE REACTION ZONES A,B,THE HIGHEST TEMPERATURE OF THE REACTION GAS MIXTURE WITHIN REACTION ZONE A BEING ABOVE THE HIGHEST TEMPERATURE OF THE REACTION GAS MIXTURE WITHIN REACTION ZONE B.
