摘　　要：合成了两种含脂肪醇聚氧乙烯醚(AEO)的双子表面活性剂:GS-TEG-AEO_(3)及GS-TEGAEO_(7),通过氢-1核磁共振波谱法和红外光谱验证了其分子结构,同时对双子表面活性剂的表面活性、泡沫性能和配方应用进行了研究。结果表明,相比AEO_(7),对应的双子表面活性剂具有更优的起泡性能和乳化能力,双子表面活性剂具有较高的表面活性(CMC=1.1×10^(-4) mol/L)。洗衣液配方研究中发现GSTEG-AEO_(7)可以代替AEO_(9),克服AEO_(9)降低黏度的缺点,同时皮脂去污更佳。Two gemini surfactants containing fatty alcohol polyoxyethylene ether(AEO)were synthesized:GS-TEG-AEO_(3) and GSTEG AEO_(7).Their molecular structure was identified by 1H-NMR and FT-IR.At the same time,the surface activity,foam performance and application on detergent of Gemini surfactant were studied.The foaming stability and emulsification ability of Gemini surfactants were better than those of AEO_(3) and AEO_(7).The Gemini surfactants have high surface activity(cmc=1.1×10^(-4) mol/L).In the study of laundry detergent formula,it was found that GS-TEG-AEO_(7) could replace AEO_(9),solving the disadvantage of reducing viscosity by AEO_(9),while achieving the better performance in sebum detergency.
