Title:
CATALYST FOR ORTHO-ALKYLATION REACTION, EXTRUSION MOLDING CATALYST FOR ORTHO-ALKYLATION REACTION, AND METHOD FOR PREPARING ORTHO-ALKYLATION REACTION PRODUCT USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/219408
Kind Code:
A1
Abstract:
The present invention relates to technology for a catalyst for an ortho-alkylation reaction, an extrusion molding catalyst for an ortho-alkylation reaction, and a method for preparing an ortho-alkylation reaction product using same and, more particularly, to a catalyst for an ortho-alkylation reaction, an extrusion molding catalyst for an ortho-alkylation reaction, and a method for preparing an ortho-alkylation reaction product using same, in which, in the ortho-alkylation reaction of a phenolic compound, an ortho-alkylation reaction product can be obtained with high selectivity and at a high conversion rate by minimizing the mass diffusion resistance of the catalyst.
