Abstract

DISCLOSED IN THE PRESENT INVENTION IS A METHOD OF PREPARING A CATALYST USED FOR PRODUCING METHACRYLIC ACIDS THROUGH GAS PHASE CATALYTIC OXIDATION OF METHACROLEIN MOLECULAR OXYGEN AND REPRESENTED BY THE FORMULA; ( PAMOBVCGEDXEYFZGOH ); WHEREIN P, MO, V, GE AND O REPRESENT PHOSPHORUS, MOLYBDENUM, VANADIUM, GERMANIUM AND OXYGEN, RESPECTIVELY; X REPRESENTS AT LEAST ONE ELEMENT SELECTED FROM THE GROUP CONSISTING OF ARSENIC, ANTIMONY, BISMUTH, ZIRCONIUM, TELLURIUM, SILVER AND BORON; Y REPRESENTS AT LEAST ONE ELEMENT SELECTED FROM THE GROUP CONSISTING OF IRON, COPPER, ZINC, CHROMIUM, MAGNESIUM, TANTALUM, MANGANESE, BARIUM, GALLIUM, CERIUM AND LANTHANUM; Z REPRESENTS AT LEAST ONE ELEMENT SELECTED FROM THE GROUP CONSISTING OF POTASSIUM, RUBIDIUM, CESIUM AND THALLIUM; AND A, B, C, D, E, F, G AND H REPRESENT THE ATOMIC RATIOS OF THE RESPECTIVE ELEMENTS, AND WHEN B = 12, THEN A = 0.5-3, C = 0.01-3, D = 0.01-3, E = 0-3, F = 0-3, G = 0.01-3, AND H IS THE NUMBER OF OXYGEN ATOMS NECESSARY FOR SATISFYING THE ABOVE ATOMIC RATIOS OF THE RESPECTIVE COMPONENTS, WHICH METHOD COMPRISES USING GERMANIUM DIOXIDE AS GE MATERIAL AND DISSOLVING AT LEAST PART OF GERMANIUM DIOXIDE IN AN AQUEOUS SOLUTION OF A HYDROXIDE OF AN ELEMENT REPRESENTED BY Z IN THE ABOVE FORMULA. THE CATALYST PREPARED ACCORDING TO THE METHOD OF THIS INVENTION IS REMARKABLY ELEVATED IN ACTIVITY IN THE METHACROLEIN OXIDATION REACTION AND ALLOWS ENHANCEMENT OF THE YIELD OF METHACRYLIC ACID.
