Azacryptophane was obtained by irradiation of the precursor diammonium chloride in the presence of γ-CD (γ-cycodextrin) in aqueous solution. In the liquid-liquid extraction, the azacryptophane showed a moderate affinity toward all alkali metal picrates without any significant selectivity, whereas it selectively extracted both Ag+ and Pb2+ cations in series of heavy metal nitrates.
在γ-CD(γ-环糊精)存在的水溶液中,通过对前体氯化二铵进行辐照获得了偶氮色玢。在液-液萃取过程中,氮杂色玢对所有碱金属苦味酸盐均表现出中等程度的亲和性,没有明显的选择性,而对重金属硝酸盐系列中的 Ag+ 和 Pb2+ 阳离子均有选择性萃取。
