| titleOfInvention | Method for preparing catalyst for methacrylic acid production |
| abstract | The present invention is a method for producing a catalyst represented by the following formula used to produce methacrylic acid by gas phase catalytic oxidation of methacrolein with molecular oxygen, Pa, Mob, Vc, Ged, Xe, Tf, Zg, Oh Wherein P, Mo, V, Ge and O represent phosphorus, molybdenum, vanadium, germanium and oxygen, respectively, and X is at least selected from the group consisting of arsenic, antimony, bismuth, zirconium, tellurium, silver and boron Represents one element, Y represents at least one element selected from the group consisting of iron, copper, zinc, chromium, magnesium, tantalum, manganese, barium, gallium, cerium and lanthanum, and Z represents potassium, rubidium , At least one element selected from the group consisting of cesium and thallium, a, b, c, d, e, f and g represent the atomic ratio of each element, b When 12, a 0.5 3, c 0.01 3, d 0.01 3, e 0 3, f 0 3, g 0.01 3, h is the number of oxygen atoms required to satisfy the valences of the respective components, germanium dioxide is used as the germanium material, and at least a part of the germanium dioxide is dissolved in an aqueous solution of the hydroxide of the element represented by Z in the above general formula. . The catalyst prepared by the present invention can significantly increase the activity in the oxidation reaction of methacrolein to increase the yield of catacrylic acid. |
