摘　　要：测定了双辛烷基二苯醚双磺酸钠(C8-DADS)和单十六烷基二苯醚双磺酸钠(C16-MADS)的耐酸性、耐碱性、热稳定性、平衡表面张力、与阳离子表面活性剂十二烷基三甲基氯化铵(DTAC)复配体系稳定性及界面张力。结果表明:C16-MADS的耐酸性、耐碱性、高温稳定性优于C8-DADS;C16-MADS临界胶束浓度(cmc)低于C8-DADS,C16-MADS cmc处的表面张力高于C8-DADS;C16-MADS/DTAC复配体系稳定性优于C8-DADS/DTAC;C8-DADS/DTAC复配体系质量比为8∶2时平衡界面张力最低,可达到10-3 mN/m数量级。The acid resistance,alkali resistance,thermal stability and surface tension of sodium dioctyl diphenyl ether disulfonate(C8-DADS)and sodium monohexadecyl diphenyl ether disulfonate(C16-MADS)were studied.The solution stability and interfacial tension of the system of C8-DADS(or C16-MADS)mixed with dodecyltrimethylammonium chloride(DTAC)were investigated.The results were as follows:the H2SO4 resistance,NaOH resistance and thermal stability of C16-MADS were better than that of C8-DADS;the critical micelle concentration(cmc)of C16-MADS was lower than that of C8-DADS,and the surface tension at cmc of C8-DADS was lower than that of C16-MADS;the solution stability of C16-MADS/DTAC was higher than that of C8-DADS/DTAC;the interfacial tension of the system with m(C8-DADS)∶m(DTAC)of 8∶2 was very low and could reach the order of 10-3 mN/m.
