Rapid synthesis of ZSM-5 zeolite catalyst for amination of ethanolamine.
ZSM-5 zeolite was rapidly synthesized in system containing ethylenediamine from the initial gel: (5-8) Na(2)O: 44 EDA:Al(2)O(3):100 SiO(2):4000 H(2)O. The crystals were lath-shaped. The effect of pretreatment and alkalinity on crystallinity was investigated. The pretreatment of silicate source can cut down the crystallization time. Tuning the system alkalinity and controlling crystallization time can ensure forming of pure crystal.
