Abstract

Abstract: Aluminosilicate ECR-1 zeolite with 12-membered channels was successfully synthesized at 120 ?C for 4 days in the absence of organic templates. Compared with ECR-1 synthesized at 100 ?C for 15 days, the crystallization of ECR-1 at 120 ?C is very fast (4 days), which are reasonably related to their difference in synthesis mechanism. Furthermore, a series of techniques such as IR spectroscopy, N2 isotherm, SEM micrograph, ICP analysis, 29Si NMR spectroscopy, and catalytic cracking of cymene were used to characterize ECR-1 zeolite, confirming the successful synthesis.

Key words: fast crystallization, organotemplate-free synthesis, ECR-1 zeolite, catalytic cracking of cymene.
