【摘要】 辛基苯酚聚氧乙烯醚硫酸钠Ｃ＿８Ｈ＿（１７）Ｃ＿６Ｈ＿４（ＯＣ＿２Ｈ＿４）＿（９，６）ＳＯ＿４Ｎａ（Ｃ＿８φＥ＿（９．６）Ｓ），溴化十二烷基三甲铁Ｃ＿（１２）Ｈ＿（２５）Ｎ（ＣＨ＿３）＿３Ｂｒ（Ｃ＿（１２）ＮＭｅ＿３），不仅能在水溶液中形成透明的均相溶液，而且混合体系的临界胶团浓度（ｃｍｃ）和γ＿（ｃｍｃ）比单一组份的ｃｍｃ和γ＿（ｃｍｃ）低。Ｃ＿８φＥ＿（９．６）Ｓ—Ｃ＿（１２）ＮＭｅ＿３的起泡能力和泡沫稳定性，在混合比为１：１左右时达最大值。在Ｃ＿８φＥ＿（９．６）Ｓ中引入２０％的Ｃ＿（１２）ＮＭｅ＿３后，Ｃ＿８φＥ＿（９．６）Ｓ—Ｃ＿（１２）ＮＭｅ＿３的润湿能力增加。当Ｃ＿（１２）ＮＭｅ＿３进一步增加时，其润湿能力下降。在Ｃ＿８φＥ＿（９．６）Ｓ中引入小于１０％的Ｃ＿（１２）ＮＭｅ＿３时，对Ｃ＿８φＥ＿（９．６）Ｓ的去污能力无明显影响。更多还原

【Abstract】 The aqueous solution of anionic-cationic surfactant. formed by C₈H₁₇C₆H₄（OC₂H₄）_9.6SO₄Na(C₈φE_9.6)and C₁₂H₂₅N（CH₃）₃Br(C₁₂NMe₃), is homogenous. The cmc and γ_cmc of C₈φE_9.6S C₁₂NMe₃ are much lower than that of the single one. The foaming ability andstability of foam of C₈φE_9.6S C₁₂NMe₃ are the maximum when the mixed ratio is near 1:1. With the increse of C₁₂NMe₃, the wettabilty of C₈φE_9.6S C₁₂NMe₃ goes up and to themaximum when the content of C₁₂NMe₃ is about 20%,and the wettability goes down whenthe content of C₁₂NMe₃ is over 20%,The effect of C₁₂NMe₃ on the detergency of C₈φE_9.6Sbecomes smaller when content of C₁₂NMe₃ is less than 10%.更多还原
