摘　　要：以碘和四正丁基碘化铵为原料,研究了四正丁基铵高聚碘的合成,考察了不同原料配比对产物聚合度的影响。采用Raman和TG分别表征了产物的结构和热稳定性;采用抑菌环法、悬液定量法和振荡烧瓶法测定了产物的杀菌性能,并讨论了其杀菌机理。结果表明,通过改变反应物配比只能生成n-Bu4NI3.0、n-Bu4NI5.0和n-Bu4NI5.43种四正丁基铵高聚碘,其中n-Bu4NI3.0只含有I-3结构,n-Bu4NI5.0只含有I-5结构,而n-Bu4NI5.4是含有I-3、I-5和I-73种结构的混合物。在3种四正丁基铵高聚碘中,n-Bu4NI3.0的热稳定性最好。四正丁基铵高聚碘具有优良的杀菌性能,其杀菌作用分两部分:微量溶于水的高聚碘产生的杀菌作用与高聚碘固体颗粒表面的杀菌作用。The tetra-n-tetrabutylammonium polyiodides were synthesized using iodine and tetra-n-tetrabutylammonium iodide as raw materials and the effect of reactants ratio on the polymerization degrees of tetra-n-butyl-ammonium polyiodides was investigated. The structure and the thermal stability of ployiodides were characterized by Raman spectroscopy and thermal gravimetric. The bactericidal performances were determined by the inhibition ring test,suspension quantitative method and shake flask method,also the bactericidal mechanism of the samples was discussed. The results show that only three kinds of tetra-n-butylammonium polyiodides which are n-Bu4NI3. 0,n-Bu4NI5. 0and n-Bu4NI7. 0can be obtained by changing the reactants ratio. Among these three products,n-Bu4NI3. 0and n-Bu4NI5. 0is made of I-3and I-5,respectively,while n-Bu4NI5. 4is a mixture of I-3,I-5and I-7. The results also indicate that n-Bu4NI3. 0is the most stable among these three kinds of tetra-n-butylammonium polyiodides. The tetra-n-butylammonium polyiodides has excellent bactericidal performance and its bactericidal effect is come from two sections： one is the bactericidal effect of the trace amounts polyiodides dissolved in water; the other is the bactericidal effect of the solid surface of polyiodides particles.
