摘要: 用与Popov等不同的多核NMR化学位移方法测定了水溶液中Na+及NH4+与18-冠-6的络合平衡常数K分别为logK=0.72和logK=1.21。对实验方法、多核线宽等进行了讨论。

Abstract: 23Na 14N NMR chemical shifts were used to study Na+, NH4+ complexes with 18-Ciown-6 in aqueous Solutions. The formation constants for[Na·18-Crown-6]+ and[NH4·18-Crown-6]+ were determined using a new method which is different from that developed by Popoy.et.al.
