摘要
辛基苯基聚氧乙烯醚硫酸钠Ｃ＿８Ｈ＿（１７）Ｃ＿６Ｈ＿４（ＯＣ＿２Ｈ＿４）＿（ｌ０）ＳＯ＿４Ｎａ（Ｃ＿８Ｅ＿（１０）Ｓ）和十二烷基７聚氧乙烯基醚硫酸钠Ｃ＿（１２）Ｈ＿（２５）（ＯＣ＿２Ｈ＿４）＿７ＳＯ＿４Ｎａ（Ｃ＿（１２）Ｅ＿７Ｓ）与溴化十二烷基三甲铵Ｃ＿（１２）Ｈ＿（２５）（ＣＨ＿３）＿３Ｂｒ（Ｃ＿（１２）ＮＭ＿３），不仅能在水溶液中形成透明的均匀溶液，而且混合体系的临界胶团浓度和γｃｍｃ比单一组分的低。Ｃ＿（１２）Ｅ＿７Ｓ－Ｃ＿（１２）ＮＭ＿３和Ｃ＿８Ｅ＿（１０）Ｓ－Ｃ＿（１２）ＮＭ＿３对极性物的加溶，随混合比的变化呈“Ｖ”型，而对非极性物的加溶呈“”型。混合比改变时，Ｃ＿（１２）Ｅ＿７Ｓ－Ｃ＿（１２）ＮＭ＿３和Ｃ＿８Ｅ＿（１０）Ｓ－Ｃ＿（１２）ＮＭ＿３溶液的粘度出现１个极大值（在１：１附近）。在Ｃ＿８Ｅ＿（１０）Ｓ中引入Ｃ＿（１２）ＮＭ＿３的量小于１０％时，Ｃ＿８Ｅ＿（１０）Ｓ－Ｃ＿（１２）ＮＭ＿３的润湿能力不变；大于１０％时，润湿能力增加，超过２０％时，润湿能力下降。混合比改变时，Ｃ＿８Ｅ＿（１０）Ｓ－Ｃ＿（１２）ＮＭ＿３对煤油的乳化能力出现两个极大值和１个极小值。
The aqueous solution of the mixture of C8H17C6H4(OC2H4)l0SO4Na (C8E10S )ald C12H25(OC2H4)7SO4Na(C12E7S)with C12H25N(CH3)3Br(C12NM3)is homogeneous.Thecmc and γcmc of C12NM.and C12E7S-C12NM3 are much lower than those of S、C12E7Sand C12NM3.With the change of mixed ratio,the formation of solubilizationcurve of polar compound(pentanol)is like“V”and the formation of solubilization ctirve ofnon-polar compound(hexane)is like by aqueous solution of C12NM3 and C12E7S-C12NM3,and the viscosity curves of the mixture are like.With the increase ofC12NM3,the wettability of C12NM3 goes up to the maximum when the content ofC12NM3 is about 20%,and the wettability goes down when the content of C12NM3 is over20%.There are two maximum points and one minimum in the emulsification curve ofC12NM3 when the content of C12NM3 changes from 0 to l.
