双烷基季铵溴盐的合成及性能研究

Synthesis of Double Alky1 Quaternary Ammonium Bromide and Reserches of its Performance

以脂肪醇为原料，合成了双辛基季铵溴盐，其产率达８０％。将其应用于大庆油田的回注水处理进行杀灭硫酸盐还原菌 （ＳＲＢ）及腐生菌（ＴＧＢ）的试验，并与１２２７杀菌剂进行了对比。结果表明：产品对ＳＲＢ及ＴＧＢ都有很强的杀灭能力，且其效果略优于１２２７杀菌剂。对于产品形成的复配杀菌剂的杀菌性能也做了一些探讨。

Using fatty alcohol as starting material, double octyl quaternary ammonium bromide was obtained. It's yield reached 80%. The synthesized bactericides was applied to recycle-water of Daqing oil-field and was tested the effect of killing SRB and TGB and was compared with the bactericide of 1227. The results showed that this bactericide had strong effect of killing SRB and TGB and was better than 1227. Some reserches to the performance of complex bactericide of the products made had done.
