Abstract:

In the presence of tetraethylammonium hydroxide, the chiral polymorph A enriched β-zeolite was synthesized. The crystallization process of polymorph A enriched β-zeolite and the key factors that lead to the enrichment of polymorph A during crystallization were investigated. The results show that the enrichment of chiral polymorph A occurred in the early stage of crystallization and the degree of the enrichment of polymorph A did not change during the crystallization.

Key words: β-Zeolite, Polymorph A, Chiral zeolite
