titleOfInvention | Catalyst precursor, method of producing catalyst, method of producing methacrylic acid and acrylic acid, and method of producing methacrylic acid ester and acrylic acid ester |
abstract | Provided are a catalyst precursor and a catalyst for producing a catalyst with a high yield of methacrylic acid, and a method for producing methacrylic acid and methacrylic acid ester. A catalyst precursor containing a heteropolyacid salt, which has a peak P1 having a 2θ of 26.16 ° ± 0.06 ° and an angle higher than the peak P1 in an X-ray diffraction pattern using anticathode Cu-Kα rays And a catalyst precursor having a peak P2 at 26.44 ° or less. In addition, a catalyst precursor is prepared in which the ratio (I1 / I2) of the height I1 of the peak P1 to the height I2 of the peak P2 is 0.05 to 0.92. Also, a catalyst is produced from the catalyst precursor, and this catalyst is used to produce methacrylic acid from methacrolein. |
