摘要
研究了苯并-15-冠醚及其亲脂类似物在氯仿中对 Li、Na 和 K 三氯乙酸的萃取。获得了萃取等温线，并确定了萃取剂向平衡水相的过渡。通过斜率分析法确定了萃取化合物中金属与冠醚的比率。确定了 Li、Na 和 K 三氯醋酸盐在苯并-15-冠醚（B15C5）和 3-叔戊基苯并-15-冠醚（tPB15C5）体系中的热力学萃取参数。分离出了晶体状的[Li3(B15C5)(TCA)3]、[Na(B15C5)(TCA)]和[K(B15C5)2](DCA)-H2O 复合物，并通过红外光谱和 X 射线衍射进行了表征。
Study of complexation of Li, Na and K trichloroacetates in extraction systems with benzo-15-crown-5 ether and its lipophilic analog
The extraction of Li, Na and K trichloroacetates by benzo-15-crown-5 ether and its lipophilic analog in chloroform has been studied. Extraction isotherms were obtained and the transition of extractants into the equilibrium aqueous phase was determined. The metal: crown ether ratios in the extracted compounds were determined by the slope analysis method. The thermodynamic extraction parameters of Li, Na and K trichloroacetates in systems with benzo-15-crown-5 ether (B15C5) and 3-tert-pentylbenzo-15-crown-5 ether (tPB15C5) were determined. The complexes [Li3(B15C5)(TCA)3], [Na(B15C5)(TCA)] and [K(B15C5)2](DCA)·H2O were isolated in crystalline form and characterized by IR spectroscopy and X-ray diffraction.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
