摘　　要：从表面活性剂分子量、表面活性剂浓度、电解质浓度、烷烃碳数等方面考察了系列烷基苯磺酸盐异构体纯化合物的油水动态界面张力行为.研究表明,表面活性剂分子量增大和电解质浓度增加使界面张力动态变化减慢,达到平衡所需时间延长;表面活性剂浓度增加和烷烃碳数增加使界面张力动态变化加快,达到平衡所需时间减少.The dynamic interfacial tension of a series of alkylbenzene sulfonates with alkane was studied from many aspects, such as the weight of the surfactant, the carbon number of the alkane, the concentration of alkali and the concentration of surfactant. The results show that the higher the molecular weight of the surfactant and the concentration of the electrolyte, the slower the interfacial tension changes, and the more time to balance. The higher the concentration of the surfactant and the carbon number of the alkane, the more quickly the interfacial tension changes, and the less time to balance.
