摘　　要：介绍了两种双季铵盐类化合物(杀菌剂1号,2号)的合成路线,并对其合成条件进行了探索,在此基础上进行了硫酸盐还原菌(SRB)的杀菌性能试验和杀菌机理探讨。当药剂浓度为80～100mg/L时,合成的两种双季铵盐对SRB的杀菌性能均优于通常使用的十二烷基二甲基苄基氯化铵(1227),而且杀菌剂1号优于2号,这是由于两个季氮原子之间所连的基团结构不同所致。Two synthetic processes for quaternary ammonium salts production (biocide 1# and biocide 2# ) are introduced and synthetic process conditions studied. On this basis, the tests on the performance in killing sulfate reduction bacteria (SRB) and mechanisms are explored. The tests show that at a concentration of 80-100 mg/L, the synthesized quaternary ammonium salts exhibit better performance for killing SRB than dodecyldimethylbenzyl ammonia chloride (1277). Whereas, germicide 1 # is superior to germicide 2 # due to their different radical structure between two nitrogen atoms.
