Abstract An extra-large-pore aluminophosphate molecular sieve with -CLO topology was successfully synthesized in low-dosage ionic liquids (ILs) via a simplified ionothermal route, for which all raw materials were firstly mixed together, and then ground into homogeneous gels followed by high-temperature crystallization. A representative -CLO-type sample was characterized by XRD, SEM, N2 physisorption, TG-DSC, CHN elemental analysis and liquid 13C NMR. The results indicate that the synthesis of -CLO topology is through the co-structure directing effect of the ionic liquid 1-ethyl-3-methylimidazolium bromide and diisopropylamine. Moreover, the optimum synthetic conditions of this material were refined. It was found that the appropriate crystallization temperature and time are 190 °C and 2 h, respectively. Owing to the facile preparation procedure and low consumption of ionic liquids, the newly synthesized extra-large-pore -CLO molecular sieve may find potential application in related areas.

具有-CLO拓扑结构的超大孔磷酸铝分子筛的简化离子热合成

摘要 在低剂量离子液体 (ILs) 中，通过简化的离子热途径成功合成了具有 -CLO 拓扑结构的超大孔磷酸铝分子筛，首先将所有原料混合在一起，然后研磨成均匀的凝胶，然后高温结晶。通过 XRD、SEM、N2 物理吸附、TG-DSC、CHN 元素分析和液体 13C NMR 表征了具有代表性的 -CLO 型样品。结果表明-CLO拓扑结构的合成是通过离子液体1-乙基-3-甲基咪唑溴化物和二异丙胺的共结构导向作用。此外，对该材料的最佳合成条件进行了细化。发现合适的结晶温度和时间分别为190℃和2h。
