摘　　要：以脱氢枞胺为原料合成了一系列松香基季铵盐Gemini表面活性剂,用IR及1H-NMR光谱对产物进行了结构表征,并对该系列表面活性剂的性能进行研究。松香基季铵盐Gemini表面活性剂具有很强的表面活性性能:临界胶束浓度(CMC)在(2.5~5.5)×10-5mol/L,表面张力23.7~30.3 mN/m,松香基季铵盐Gemini表面活性剂还具有很强的乳化性能及泡沫性能。The rosin-based quaternary ammonium Gemini surfactants are synthesized from dehydroabietylamine by reaction with α,ω-bisbromoalkanes.Their structures are characterized by IR and 1H-NMR spectroscopy.The surface activities of them are investigated and analyzed.The results show that they have higher surface activities for their critical micelle concentration values between(2.5-5.5)×10-5 mol/L,γCMC values of 23.7-30.3 mN/m,excellent emulsifying power(with benzene) and foaming power.
