摘要
利用自制的双卤代醚与长链叔胺,合成了双季铵盐杀菌剂,并对其结构进行了红外表征,评价了其杀菌效果,并与12 2 7进行了杀菌性能的对比。实验结果表明:双季铵盐对SRB具有良好的杀菌性能,而且杀菌能力也明显优于12 2 7,在菌量较高的情况下(1.5×10 8个·mL-1)杀菌浓度仅为5 0mg·L-1,就能10 0 %杀死SRB ,是一种很有应用前景的新型杀菌剂。
The double-quaternary ammonium salt was synthesized by using double-halogened ether and long-carbon-chain ter-amine and characterized with IR. The results show the double-quaternary ammonium salt has better bactericidal effect on sulfated reducing bacteria(SRB) compared with 1227 and can thoroughly kill SRB at 80～100mg·L -1.It is a powerfully potential bactericide.
