摘　　要：研究了二烷基苯磺酸盐(DAS)与重烷基苯磺酸盐(HABS)/十二烷基苯磺酸盐(LAS)复配体系在癸烷中的界面张力特性.结果表明:当LAS质量分数为30%或40%时,HABS与DAS以不同比例复配,三元体系在降低界面张力方面存在明显的协同效应;当LAS质量分数低于20%或高于50%时,HABS与DAS无协同作用.在LAS质量分数为30%,HABS与DAS复配比例为2∶1、1∶1,或LAS质量分数为40%,HABS与DAS复配比例为1∶2时,界面张力均可降低至10-3m N/m数量级,而且复配后三元体系达到超低界面张力的复配比例区域明显变宽.The interfacial tension properties of complex system of dialkyl benzene sulfonate（DAS） and heavy alkyl benzene sulfonate（HABS）/dodecyl benzene sulfonate（LAS） in decane were investigated. The results showed that： when the content of LAS was 30% or 40%, with different complex proportion of HABS to DAS, obvious synergic effect existed in terms of reducing interfacial tension in the ternary system; the content of LAS was less than 20% or more than 50%, there was no synergic effect between HABS and DAS.When the content of LAS was 30%, with the complex ratio of HABS to DAS 2∶1 and 1∶1, or when the content of LAS was 40%, with the complex ratio of HABS to DAS 1∶2, the interfacial tension could be reduced to10-3m N/m order of magnitude. And the area of the ternary complex system which achieved ultra-low interfacial tension was significantly widened.
