Abstract: IN A PROCESS FOR THE PREPARATION OF ACROLEIN OR ACRYLIC ACID OR A MIXTURE THEREOF FROM PROPANE, THE PROPANE IS SUBJECTED, IN A FIRST REACTION STAGE, TO A PARTIAL DEHYDROGENATION UNDER HETEROGENEOUS CATALYSIS TO GIVE PROPANE, OF THE COMPONENTS CONTAINED IN THE PRODUCT GAS MIXTURE FORMED IN THE FIRST REACTION STAGE OTHER THAN PROPENE AND PROPANE AT LEAST A PORTION OF THE MOLECULAR HYDROGEN PRESENT IS THEN SEPARATED OFF ROM SAID MIXTURE AND THE PRODUCT GAS MIXTURE IS THEN USED FOR THE PREPARATION OF ACROLEIN AND/OR ACRYLIC ACID GAS-PHASE CATALYTIC PROPYLENE OXIDATION, MOLECULAR NITROGEN BEING PRESENT FOR DILUTING THE REACTION GAS MIXTURE DURING THE PROPYLENE OXIDATION.
