Abstract

IN A PROCESS FOR THE CONTINUOUS HETEROGENEOUSLY CATALYZED GAS-PHASE OXIDATION OF PROPYLENE TO ACROLEIN, ACRYLIC ACID OR A MIXTURE THEREOF IN AN OXIDATION REACTOR WHOSE FEED GAS MIXTURE , COMPRISES, APART FROM PROPYLENE AND MOLECULAR OXYGEN AS OXIDANT, ONLY AT LEAST ONE DILUENT GAS WHICH IS ESSENTIALLY INERT UNDER THE CONDITIONS OF THE HETEROGENEOUSLY CATALYZED GAS-PHASE OXIDATION AND WHERE, IN CONTINUOUS OPERATION, AT LEAST A PART OF THE ESSENTIALLY INERT DILUENT GASES PRESENT IN THE PRODUCT GAS MIXTURE IS SEPARATED OFF THEREFROM AND IS REUSED AS A CONSTITUENT OF THE FEED GAS MIXTURE TO THE OXIDATION REACTOR, THE ESSENTIALLY INERT DILUENT GAS MIXTURE COMPRISES MORE THAN 85 BY VOLUME OF AT LEAST ONE SATURATED HYDROCARBON HAVING FROM 1 TO 5 CARBON ATOMS.
