| 摘 要： | 以四正丁基碘化铵和单质碘为原料,合成了具有不同聚合度的固体高聚碘—四正丁基多碘化铵,测定了其熔点,并对其进行了拉曼光谱分析,讨论了高聚碘中多碘链的结构。研究结果表明：碘三、碘七和碘十一形式的四正丁基多碘化铵中的多碘链有相同的基本结构单元,即直线型的I3-;而碘五和碘九形式的四正丁基多碘化铵中多碘链有相同的基本结构单元,即直线型的I5-。碘七、碘九和碘十一形式的四正丁基多碘化铵中的多碘链结构分别呈现三角锥型、V型和变形的四方锥型。

| Abstract: | N-tetrabutylammonium polyiodide bactericides were synthesized by n-tetrabutylammonium iodide and iodine with different stoichiometric ratios.The structures of the polyiodide anion chains of the polyiodides were analyzed by Raman spectroscopy.The results show that the polyiodide anion chains of n-tetrabutylammonium triiodide,heptaiodide and undecaiodide have the same basic structural unit-I3-,with linear structure;and the polyiodide anion chains of ntetrabutylammonium pentaiodide and nonaiodide have the same basic structural unit-I5-,with linear structure.The structures of the polyiodide anion chains of n-tetrabutylammonium heptaiodide,nonaiodide and undecaiodide present broach-shape,V-shape and transmutative quartet cone-shape separately. |
