在萃取研究过程中,合成了10种由四溴(或碘)合铟(Ⅲ)配阴离子与苯并-15-冠-5或二苯并-18-冠-6合钾(或钠)配阳离子相结合所形成的新型固体配合物。经元素分析、红外光谱及差热-热重等方法对配合物进行了表征。通过与相应的冠醚碱金属苦味酸盐配合物结构性质的对比,较合理地解释了这两类萃取体系之间存在的某些差别。
In the course of the extraction, 10 kinds of potassium (or sodium) complexes with tetrakis (or iodine) indium (Ⅲ) anions and benzo-15-crown-5 or dibenzo-18-crown- Cation formed by the combination of a new solid complex. The complexes were characterized by elemental analysis, infrared spectroscopy and differential thermal-thermogravimetry. Some differences between the two types of extraction systems are reasonably explained by the comparison with the corresponding structural properties of the corresponding crown ether alkali picrate complexes.
