研究了添加三（氧乙烯）十二烷基醚（C12EO3）对六酸蔗糖和CTAB水溶液在添加盐（NaBr）存在下的物相和流变性能的影响。在CTAB和C16SE体系中加入亲脂性非离子表面活性剂C12EO3形成粘弹性溶液。除无盐CTAB/C12EO3水溶液体系外，零剪切粘度在C12EO3的一定混合分数下达到最大值。在CTAB体系中加入盐对其流变性能有很大影响，但在C16SE体系中则保持不变。在离子体系中，C12EO3的最大粘度的混合分数取决于盐的浓度。(C) 2004年Elsevier B.V.出版
The effect of adding tri(oxyethylene) dodecyl ether (C12EO3) on the phase and rheological behavior of sucrose hexadecanoate and CTAB aqueous solutions in the presence of added salt (NaBr) was investigated. Viscoelastic solutions are formed in CTAB and C16SE systems upon addition of lipophilic nonionic surfactant C12EO3. The zero-shear viscosity shows a maximum at a certain mixing fraction Of C12EO3, except in the case of the aqueous CTAB/C12EO3 system in the absence of salt. The rheological properties are strongly affected by the addition of salt to the CTAB systems but they remain unaltered in the case of C16SE systems. In ionic systems, the mixing fraction of C12EO3 for the maximum viscosity depends on salt concentration. (C) 2004 Published by Elsevier B.V.
