摘　　要：低碳醇因为与表面活性剂有很好的协同效应,经常被用作表面活性剂的助剂。考察了低碳醇对低质量分数α-烯烃磺酸钠溶液(以0.02%为例)泡沫性能的影响。结果表明,高质量分数(0.2%)α-烯烃磺酸钠溶液与低碳醇协同效应不明显;低质量分数(0.02%)α-烯烃磺酸钠溶液与异丙醇、正丁醇和异戊醇有明显的协同效应,即这3种醇能大幅度增加低质量分数α-烯烃磺酸钠溶液的泡沫性能,且随醇碳数增加,低碳醇增加α-烯烃磺酸钠溶液泡沫性能的幅度越大;但甲醇和乙醇基本不能增强低质量分数α-烯烃磺酸钠溶液的泡沫性能。高Na Cl和高Ca Cl2质量分数下,低质量分数α-烯烃磺酸钠溶液的泡沫性能很差,而异戊醇能大幅度提高其泡沫性能,且随异戊醇质量分数增加,增效作用增强。Low carbon alcohol is often used as additives for surfactant because of its better synergistic effect with surfactant. This paper in- vestigates the effect of low carbon alcohol on the foaming performance of α-olefine sodium sulfonate solution with low mass fraction of 0.02%. The result shows that the synergistic effect of this solution with high mass fraction of 0.2% is not obvious on the low carbon alcohol; there exist obvious synergistic effects between the α-olefine sodium sulfonate solution with low mass fraction of 0.02% and such three alco- hols as isopropanol, n-butyl alcohol and isoamyl alcohol, respectively, showing that these alcohols can greatly improve the foaming performance of low mass fraction sulfonate solution, and with the increasing of the carbon number of alcohols, the foaming performance becomes better and better, except for methanol and ethanol. Also, NaCl and CaCl： with high mass fraction may not be directly used to improve the foaming performance of the solutions with low mass fraction, while isoamyl alcohol can do it well in presence of the NaCl and CaCl2, and with the increasing of isoamyl alcohol＇ s mass fraction, the synergism effect also becomes better and better.
