摘要: 以自制的5种连接基团为2-羟丙基(-3(OH)-),两侧疏水基团为不同碳数烷基链的阳离子季铵盐双子(Gemini)表面活性剂(8-3(OH)-8,8-3(OH)-12,8-3(OH)-16,12-3(OH)-12和16-3(OH)-16)为研究对象,测定了它们不同浓度水溶液的表面张力,不同pH下的泡沫性能以及乳化能力。结果表明:5种表面活性剂的cmc分别为12.3×10-5,15.5×10-5,6.8×10-5,2.9×10-5和1.2×10-5 mol/L,γcmc分别为46.04,37.20,39.61,39.34和38.12 mN/m;酸性条件(pH=2)下5种表面活性剂的发泡力均较中性条件下有所提高,无论是在酸性还是在中性条件下,8-3(OH)-12在5种表面活性剂中发泡力最好;在酸性条件(pH=2)下,5种表面活性剂的乳化能力均较中性条件下有明显提高。

Abstract: A Series of quaternary ammonium Gemini surfactants,8-3(OH)-8,8-3(OH)-12,8-3(OH)-16,12-3(OH)-12 and 16-3(OH)-16 were synthesized using epoxy chloropropane and various alkyl tertiary amines as starting materials.Surface activity,forming performance at various pH conditions,and emulsifying properties were investigated.The critical micelle concentration (cmc) of the five kinds of surfactant are 12.3×10-5,15.5×10-5,6.8×10-5,2.9×10-5 and 1.2×10-5 mol/L respectively,and their equilibrium surface tension (γcmc) are 46.04,37.20,39.61,39.34 and 38.12 mN/m respectively.The surfactant 8-3(OH)-12 displays outstanding foaming and emulsifying properties in both neutral and acidic condition (pH=2).The foam performance and emulsifying property of these Gemini surfactants could be promoted greatly under acidic condition.
