The following conclusions have been gotten from a large amount of experiments and determinations: Triiodide, pentaiodide, heptaiodide, nonaiodide, undecaiodide of solid tetra-n-butyl ammonium polyiodides and tetrabutyl ammonium bromide polyiodides can be synthesized by solid phase process which is a economic easy way, while its not suitable for synthesizing solid tetramethyl ammonium polyiodides; Solution polyiodides of triiodide, pentaiodide can be synthesized through the complexation process, and TX-10 is a better complexing agent; Triiodide, pentaiodide, heptaiodide resinic polyiodides were synthesized by ion-exchange of resinifying process, and that is a viable easy way.
在大量实验和分析的基础上,可得到以下结论:用固相法可以合成出碘三、碘五、碘七、碘九和碘十一形式的正四丁基多碘化铵固体高聚碘和四丁基多碘化溴化铵固体高聚碘系列化合物,是制备高聚碘的经济、方便的合成方法,但此法对合成四甲基多碘化铵固体高聚碘系列化合物并不适用;TX-10是合成溶液高聚碘较佳的络合剂,通过其络合作用可以合成出碘三和碘五形式的溶液高聚碘;采用树脂法,通过离子交换,合成出了碘三、碘五和碘七形式的树脂高聚碘,此法简单可行。
