摘要

利用三甲胺盐酸盐、环氧氯丙烷和十二烷基二甲基叔胺(DMA12)等原料合成了2-羟基-N1,N1,N3,N3-五甲基-N3-十一烷基丙烷-1,3-双氯化铵(HPUDC)。实验发现:80℃,中间产物3-氯-2-羟丙基三甲铵和DMA12的摩尔比为1∶1.5,反应7h时,HPUDC的产率可达62.8%,并以1 H NMR和IR验证了结构。以海上某油田水样为处理对象,评价了HPUDC针对硫酸盐还原菌的杀菌性能,结果显示:25mg/L时,其杀菌率为99%,明显好于1227和戊二醛;浓度小于25mg/L时,其杀菌率也优于相应的对称型双季铵盐乙撑基双(十二烷基二甲基)氯化铵。
        A dissymmetric bis-quaternary ammonium salt surfactant named 2-hydroxy-N 1,N 1,N 1,N 3,N 3-pentamethyl-N 3-undecylpropane-1,3-diaminium chloride(HPUDC) was synthesized by using trimethy-lamine hydrochloride,epichlorohydrin and dimethyldodecylamine(DMA12).The structure of the HPUDC was confirmed by the 1 H NMR and IR.The effects of different reaction conditions on the yield of the HPUDC were studied and it was found that the max yield was 62.8% when the reaction temperature was 800℃,n(3-chlorin-2-hydroxy propyl trimethylammonium chloride) ∶n(DMA12) =1∶1.5and reaction time was 7h.The bactericidal performance of HPUDC used in one off-shore oil field water for sulfate reducing bacteria was also studied and the results showed that the bactericidal effect could be up to 99%at 25mg / L.Its performance is much better than the 1227and glutaraldehyde,which is also superior to the relevant symmetric bis-quaternary ammonium salt surfactant,ethylene di(dimethyldoldecyl ammonium chloride),when the concentration is less than 25mg / L.
