摘要：

以溴代十六烷和镁屑制备的格氏试剂（Grignard reagent）与氯化二苯基膦反应得到十六烷基二苯基膦，用氯甲基聚苯乙烯（Cl含量约为17%）为载体进行固载反应，制备了固载型季钅粦盐，并进行了结构表征。采用标准平皿计数法研究了固载型季钅粦盐的杀菌性能，考察了反应时间、反应温度、交联的氯甲基聚苯乙烯溶胀时间对产物固载率和杀菌性能的影响。实验结果表明，在适宜的反应条件下，十六烷基二苯基膦在氯球上的固载率可达9.2%，此时制得的固载型杀菌剂的杀菌率可达98.3%，且可重复使用。用稀盐酸进行活化恢复杀菌性能。

Abstract:

A polymeric immobilized quaternary phosphonium salt was synthesized by using chloromethylated polystyrene（Cl content about 17%） as carrier and reaction of Grignard reagent of 1-bromohexadecane with chlorodiphenyl phosphine，and its chemical structure was characterized by Fourier transform infrared spectroscopy（FTIR）. By using standard plate counting method，the bactericide had high bactericidal efficiency，and the effects of main factors on immobilized ratio and bactericidal efficiency were studied. The experimental results showed that under appropriate condition，immobilized ratio could reach 9.2%，bactericidal ratio was 98.3% for 8 h，and this immobilized phosphonium salt could be reactivated by hydrochloric acid for re-use.
