Abstract
The present invention relates to a technology for an extrusion-molded catalyst for ortho-alkylation reaction and its preparation method, and more specifically, to an extrusion-molded catalyst for ortho-alkylation reaction that can minimize the mass diffusion resistance of the catalyst in the ortho-alkylation reaction of a phenolic compound to obtain an ortho-alkylation reaction product with high selectivity and conversion rate, and a method for preparing the ortho-alkylation reaction product using the same.
