摘　　要：合成了一种阴离子型双醚双苯磺酸盐Gemini表面活性剂,测定该系列Gemini表面活性剂水溶液的表面张力(γcmc)分别为:32.00mN/m、28.41 mN/m、29.76 mN/m、33.20 mN/m,临界胶束浓度(cmc)分别为:0.79mmol/L、0.87 mmol/L、1.02 mmol/L、0.84 mmol/L;该Gemini表面活性剂(DPDAS-12)可在无碱,浓度为0.35%条件下,将油/水界面张力降至1.2×10-3mN/m的超低水平;可有效改变岩石表面润湿性,可将亲油表面(θ=114°)改变为弱亲油(θ=69.3°),可将亲水表面(θ=26.0°)改变为弱亲水表面(θ=34.0°)。A new anionic diaether diphenyl sulfonate Gemini surfactant was synthesized in study. The γcmc of them were 32. 00mN/m,28. 41 mN/m,29. 76 mN/m,33. 20 mN/m respectively, and cmc of them were 0. 79mmol/L,0. 87 mmol/L, 1.02 mmol/L,0. 84 mmol/L respectively,The system with no alkaline could reduce the interfacial tension of oil/water to 1.2 × 10^-3 mN/m under the condition of concentration of Gemini surfactant （ DADPS - 12 ） 0. 35 %. Gemini surfactant agent could change wettability of solid surface effectively： oil -wet surface -property（ θ= 114°） turn to weak oil -wet （θ = 69.3°）, hydrophilic surface - property （ θ= 26. 0° ） turn to weak hydrophilic （ θ = 34. 0° ）.
