AN IMPROVED METHOD FOR THE SELECTIVE VAPOR PHASE OXIDATION OF ACROLEIN TO ACRYLIC ACID IN A RECIRCULATING SOLIDS REACTOR SYSTEM USING A PARTICULATE MOLYBDENUM VANADATE MULTIMETAL OXIDE AS OXIDANT INVOLVING SPECIFIC REACTANT CONCENTRATIONS (PREFERABLY 5 MOL TO 30 MOL 40024108ROPYLENE, 0 TO 20 MOL OXYGEN, 0 TO 70 MOL WATER, AND THE REMAINDER INERT GAS), SOLIDS PARTICLE SIZE (20 TO 300 MICROMETERS) TEMPERATURE 9250 TO 450°C) AND GAS (1 TO 15 SECONDS) AND SOLIDS (2 TO 60 SECONDS) RESIDENCE TIMES. SUCH A PROCESS LEADS TO IMPROVED SELECTIVITY, CONVERSION AND SOLIDS CONVERSION RATIO.
