    • A process for producing a catalyst with which methacrolein, isobutyraldehyde, or isobutyric acid can be catalytically oxidized in a vapor phase to produce methacrylic acid in high yield with high selectivity. The process, which is for producing a catalyst with which methacrolein, isobutyraldehyde, or isobutyric acid can be catalytically oxidized in a vapor phase to produce methacrylic acid, is characterized by comprising: (a) a step in which compounds each containing any of molybdenum, vanadium, phosphorus, copper, cesium, and NH4 are mixed with water to prepare an aqueous solution or aqueous dispersion (hereinafter, both are collectively referred to as a slurry) of these compounds; (b) a step in which the slurry obtained in the step (a) is dried to obtain a dried slurry; (c) a step in which the dried slurry obtained in the step (b) is burned to obtain a burning product; (d) a step in which the burning product obtained in the step (c) is mixed with water and the mixture is separated by filtration into an aqueous solution and a water-insoluble matter; and (e) a step in which the water-insoluble matter obtained in the step (d) is dried to obtain a dried water- insoluble matter.
    • 一种制备催化剂的方法,其中甲基丙烯醛,异丁醛或异丁酸可以在气相中催化氧化,以高产率高选择性生产甲基丙烯酸。 用于生产甲基丙烯醛,异丁醛或异丁酸可以在气相中催化氧化以产生甲基丙烯酸的催化剂的方法的特征在于包括:(a)一种步骤,其中各自含有钼, 将钒,磷,铜,铯和NH 4与水混合以制备这些化合物的水溶液或水分散体(以下统称为浆料) (b)将步骤(a)中获得的浆料干燥以获得干燥的浆料的步骤; (c)将步骤(b)中获得的干燥浆料燃烧以获得燃烧产物的步骤; (d)将步骤(c)中获得的燃烧产物与水混合并将混合物通过过滤分离成水溶液和水不溶性物质的步骤; 和(e)将步骤(d)中得到的水不溶性物质干燥以获得干燥的不溶于水的物质的步骤。
