Abstract

This project reported the synthesis of novel heterocyclic nitrogen-based ionic liquid molecules as novel structure-directing agents (SDAs) in the synthesis uf zeulite microporous materials. The first part of this project discussed about the synthesis of several types of heterocyclic nitrogen-based SDAs. The prepared SDAs were then characterized using IR, IH NMR, TG/DTG and CHN analyses. The experiment was then followed by the formation study of iron-containing AIPO-5 crystals in the presence of phosphorous acid (H3P03) by using imidazolium-based SDA ([bdmim ]el) under ionothermal condition. The formation process of FeAPO-5 during the ionothermal synthesis was monitored by microscopic and spectroscopic methods. The roles of Fe3+ and H3POJ in the formation of the FeAPO-5 framework were investigated. Possible mechanism for the growth of FeAPO-5 crystals was proposed based on the experimental results.
