This project will explore the synthesis, characterization and application of this molecular sieve in catalysis. First, Yβ dual-microporous zeolite molecular sieve was prepared by hydrothermal method, and its structure was characterized by XRD, SEM, TEM and other methods. Secondly, the addition of tetrabutylammonium solution was used for modification, and its surface properties were analyzed. Finally, the modified Yβ dual-microporous zeolite molecular sieve was used for acetone-acetic acid esterification reaction, and its catalytic performance was studied. This study is expected to provide new ideas and methods for the development of new zeolite catalysts.Keywords: Yβ dual-microporous zeolite molecular sieve; synthesis; characterization; catalytic performance.
