摘　　要：磺酸盐Gemini表面活性剂因具有较高的表面活性、耐温及抗盐性好等特点而受到国内外学者的广泛关注。分别采用量高法和搅动法测定了磺酸盐Gemini表面活性剂TADS-10的润湿性能和起泡性能,采用分水时间法测定了TADS-10对液体石蜡的乳化能力。结果表明:磺酸盐Gemini表面活性剂TADS-10亲油表面的接触角随浓度的增大而减小,而亲水表面的接触角随浓度的增大而增大;在临界胶束浓度附近,TADS-10的起泡性能趋于稳定;随着温度的升高,其起泡性能增强;与传统表面活性剂相比,TADS-10具有较强的乳化性能。Sulfonate Gemini surfactant have attracted considerable interest because of their excellent surface activities,temperature tolerance and salt resistance.The wetting properties and foaming performance of TADS-10 were determined by hypsometry method and stirring method.The emulsifying properties of TADS-10 to liq-uid paraffin was measured by water diversion method.The results showed that with the increasing of sulfonate Gemini surfactant TADS-1 0 concentration,the contact angle of the hydrophobic surface was reduced,and the hydrophilic surface was increased.Around the CMC,foaming performance was almost unchanged;with rising of the temperature,foaming performance was enhanced.Compared with the traditional surfactants,TADS-10 had excellent emulsifying properties.
