摘　　要：研究了C12-烷基糖苷表面活性剂(C12-APG)与正构烷烃的油/水界面活性,并考察了表面活性剂浓度以及温度对界面活性的影响,实验结果表明,C12-APG表面活性剂具有较好的界面活性,达到平衡所需时间较短,且具有一定的烷烃选择性;表面活性剂浓度增加对界面张力的影响不大;随着温度的升高界面张力减小。The interfacial activity of C12-Alkyl glycoside （C12-APG） with alkanes was studied in this research. The effects of surfactant concentration, electrolyte concentration and temperature on interfacial activity were also investigated. The experimental results show that C12-APG surfactant has good interfacial activity. It needs very short time to attain balance and has certain alkanes selectivity. Increasing the concentration of surfactant has little effect on interfacial tension. The interfacial tension decreases with the increase of temperature.
