Abstract
PURPOSE: To provide a crystalline oxide having the crystal structure similar to that of (VO)2P2O7, obtained from the oxides of V, Fe, Cr, Al, and P, and useful as a gaseous phase oxidation catalyst, especially a catalyst for the preparation of maleic anhydride from a 4C hydrocarbon.
CONSTITUTION: The objective crystalline oxide of formula (0<x≤0.4; 0≤y≤0.4; 0≤z≤0.4; 0<x+y+z≤0.4) is prepared by (1) dissolving a vanadium source such as vanadium pentoxide, a phosphorus source such as phosphorus pentoxide, and halides or hydroxy acid salts of iron, chromium, Al, etc. in water, (2) precipitating a crystalline precursor from the solution e.g. by concentration or evaporation to dryness, and (3) calcining the precursor at about 300W700°C in air, nitrogen atmosphere, etc. The atomic ratios of the elements in the raw materials are; P/(V+Fe+ Cr+Al)=about 0.8W1.25, and Fe/(V+Fe+Cr+Al) or (Fe+Cr+Al)/(V+Fe+ Cr+Al)=about 0.001W0.4.
