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

摘要

The present invention provides a molded catalyst for use in the manufacture of methyl methacrylate, for manufacturing methyl methacrylate from a starting material of methyl ±-hydroxyisobutyrate by a vapor phase contact reaction, wherein the molded catalyst for use in the manufacture of methyl methacrylate is characterized in that the molded catalyst includes a synthetic faujasite type zeolite, a lamellar aluminum silicate compound, and a synthetic lamellar magnesium silicate compound, the weight ratio of the lamellar aluminum silicate compound and the synthetic lamellar magnesium silicate compound being 1:5 to 6:1.
