A new synthesis route for the zeolitic imidazolate framework ZIF-4 using imidazolium imidazolate is reported. Additionally, the ionic liquid-derived material is compared to conventional ZIF-4 with respect to the powder X-ray diffraction pattern pattern, nitrogen uptake, particle size, and separation potential for olefin/paraffin gas mixtures. Higher synthesis yields were obtained, and the different particle size affected the performance in the separation of ethane and ethylene.
报道了一种使用咪唑鎓咪唑的沸石咪唑酯骨架 ZIF-4 的新合成路线。此外，还比较了离子液体衍生材料与传统 ZIF-4 的粉末 X 射线衍射图谱、氮气吸收、粒径和烯烃/烷烃气体混合物的分离潜力。获得了更高的合成产率，不同的粒径影响了乙烷和乙烯分离的性能。
