摘要: 以溴代十四烷和二乙烯三胺为原料,合成了表面活性剂十四烷基二乙烯三胺(C14DETA)。采用红外光谱和核磁共振氢谱对C14DETA进行了结构表征。通过研究其电导率可逆、pH可逆和与SDS协同作用的开启,证明了C14DETA具有良好的CO2开关性能。测定了十四烷基二乙烯三胺碳酸氢盐(C14DETA-CO2)和SDS/C14DETA-CO2复配体系的临界胶束浓度,分别为1.0×10-2和1.0×10-4 mol/L。通过测定C14DETA-CO2对正癸烷/水体系的乳化性能,证明了C14DETA-CO2具有良好的乳化性能,所制得乳状液为W/O型,其较佳乳化条件为:C14DETA-CO2的质量分数4%,油水体积比1∶1或1∶2。

Abstract: Surfactant tetradecyldiethylenetriamine (C14DETA) was synthesized with 1-bromotetradecane and diethylenetriamine as starting materials.Its structure was characterized by FT-IR and 1H NMR spectrum.Measurement of reversibility of conductivity,reversibility of pH values,and the opening action of synergistic effect with SDS demonstrate the good CO2 switchability of C14DETA.The critical micelle concentrations (cmc) of tetradecyldiethylenetriamine bicarbonate (C14DETA-CO2) and the mixed system of SDS/C14DETA-CO2 are 1.0×10-2 and 1.0×10-4 mol/L respectively.Results of emulsifying performance of C14DETA-CO2 for n-decane/water system prove the good emulsifying power of C14DETA-CO2.The emulsion is water-in-oil type,and its better emulsifying conditions are:mass fraction of C14DETA-CO2,4%;and the volume ratio of oil/water,1∶1 or 1∶2.

Key words: CO2 switchable surfactant, characterization, critical micelle concentration, performance
