中文摘要:
      以三氟乙酸乙酯和N,N-二甲基乙二胺为原料经酰化反应制得中间体N- [2-(二甲基氨基)乙基]-2,2,2-三氟乙酰胺(NDAET);然后将NDAET与溴代十二烷发生季铵化反应得到一种新型氟化季铵盐表面活性剂(NDAET-12),其结构经1HNMR,IR表征。表面性能结果表明 NDAET-12具有较高的表面活性,水溶液的临界胶束浓度为4.62*10-2mmol/L,对应的CMC的表面张力为24.78 mN/m。
英文摘要:
      A compound N-[2-(Dimethylamino)ethyl]-2,2,2-trifluoroacetamide (NDAET) was obtained by acylation using ethyl trifluoroacetate and N,N-dimethylethylenediamine as raw materials.Then quaternization of NDAET with bromododecane to obtain a novel fluorinated quaternary ammonium salt surfactant (NDAET-12).The structure were characterized by FTIR,1 HNMR and 13 CNMR.The surface performance results showed that NDAET-12 had a high surface activity,the critical micelle concentration of the aqueous solution was 4.62?10-2mmol/L and the corresponding CMC surface tension was 24.78 mN/m.
