Synthesis of ZSM-23 Zeolite Using Isopropylamine as Template

Abstract

Abstract: The formation of different zeolite crystal phases was found in the hydrothermal system of isopropylamine-silica sol-NaAlO2-H2O. ZSM-23 zeolite with controllable morphology can be synthesized in this system by changing synthesis conditions, especially the SiO2/Al2O3 molar ratio and template concentration. Needle-shaped ZSM-23 with length of 150–200 nm was obtained steadily under the appropriate conditions.

Key words: ZSM-23 zeolite, ZSM-5 zeolite, template, isopropylamine
