MOLDED CATALYST FOR USE IN MANUFACTURE OF METHYL METHACRYLATE, AND METHOD FOR MANUFACTURE OF METHYL METHACRYLATE USING SAME

摘要

According to the present invention, there is provided a catalyst molded article for producing methyl methacrylate in which methyl methacrylate is produced by gas phase catalytic reaction using methyl α-hydroxyisobutyrate as a raw material, wherein the catalyst molded article is layered with a synthetic fosasite-type zeolite. It contains an aluminum silicate compound and a synthetic layered magnesium silicate compound, wherein the weight ratio of the layered aluminum silicate compound and the synthetic layered magnesium silicate compound is 1:5 to 6:1, providing a catalyst molded article for producing methyl methacrylate can do.
