摘要: 为获得耐无机盐的开关型表面活性剂,研究了在长链烷基和叔胺基之间嵌插聚氧乙烯(EO)片段的N-十二烷基聚氧乙烯醚(3)基-N,N-二甲基叔胺(C12EO3A)的CO2开关响应性能。电导率和荧光探针实验结果表明C12EO3A具有明显的CO2开关响应性能;与结构相近的N-十二烷基-N,N-二甲基叔胺碳酸氢盐([C12AH]+HCO3-)相比,C12EO3A碳酸氢盐([C12EO3AH]+HCO3-)的临界胶束浓度更小,在饱和NaCl水溶液中仍可发挥出色的表面活性剂功能。

关键词: 开关型表面活性剂, CO2响应, 乙氧基化叔胺, 耐盐性

Abstract: In order to obtain a switchable surfactant that has inorganic salt tolerance,CO2-switching responsive performance of N-dodecyl polyoxyethylene (3)-N,N-dimethyl tertiary amine (C12EO3A),embedded with polyoxyethylene (EO) segment between the long-chain alkyl group and tertiary amino group was investigated.Results from conductivity test and uorescence probe test showed that C12EO3A displays conspicuous CO2-swiching responsive efficacy.Comparing with bicarbonate of N-dodecyl-N,N-dimethyl tertiary amine ([C12AH]+HCO3-),with bicarbonate of C12EO3A ([C12EO3AH]+HCO3-) that has similar structure,critical micelle concentration of the latter is smaller,and shows outstanding surfactant functions even in saturated NaCl aqueous solution.

Key words: switchable surfactant, CO2-responsive, ethoxylated tertiary amine, salt tolerance
