4,13-二硫杂苯并-18-冠-6的合成及对Ag+的选择性萃取
Synthesis of 4,13-Dithio Benzene and-18-Crown-6 and Its Selective Extractability on Ag+
摘要
Abstract
4,13-Dithio benzene and-18-crown-6( DSB18C6) was synthesized by esterification, reduction and nucleophilic substitution reaction. The structural characterization was performed using proton nuclear magnetic resonance spectroscopy and X-ray single crystal diffraction, the selective binding to Ag+ was investigated by solvent extraction. The results show that DSB18C6 has a high selective extraction ability for Ag+ in the co-existence of Cu2+, Pb2+, Zn2+ and Ni2+ ions. The extraction efficiency of DSB18C6 to Ag+ was 95％.关键词
