摘要
综述了目前研究得最系统的一类孪二连型 (二聚体型 )表面活性剂———双季铵盐类表面活性剂α,ω 亚烷基双(二甲基烷基溴化铵 ) ,认为可成为有广泛应用前景的一种油田化学剂。简略介绍了此类化合物的化学结构和合成方法 ,比较详尽地介绍了此类表面活性剂的物化性质 ,包括 :临界胶束浓度 ;胶束聚集数 ;胶束微观结构与溶液流变性 ;气液和固液界面相行为 ;水溶液中液晶形成 ;与单体型和三聚体型表面活性剂的比较 ;其他性质 (杀菌能力 ,与常规表面活性剂的配伍性 )。
This review article introduces the most studied class of gemini, dimeric, surfactants-- gemini quarternary ammonium salts alkanediyl α,ω bis(dimethylalkylammonium bromide) as promising oilfield chemicals. Their chemical structure and methods of synthesis are briefly described. Their physicochemical properties are summarized in some detail: critical micelle concentration; micelle aggregation number; microstructure of micelles and solution rheologic behavior; phase behavior at gas/liquid and solid/liquid interfaces; liquid crystal formation in aqueous solutions ; comparison of mono , di ,and trimeric species; others(bactericidal ability and compatibility with common surfactants).
