摘要: 以十二烷基二甲基叔胺(12DMA)为主原料,在酸性条件下,合成了一种羟丙基双子型阳离子季铵盐1,3-二(烷基二甲基氯化铵)异丙醇(ADAC)。利用亚甲基蓝逆向滴定法测得产物纯度为98.63%,熔点为70.7~71.2 ℃。用FT-IR和1H NMR对产物进行了结构表征。以单因素试验为基础,采用响应面法优化的ADAC合成工艺条件为:反应温度91 ℃、反应时间11 h、溶剂为异丙醇、n(12DMA)∶n(盐酸)=2.03∶1、转速250 r/min。在此条件下,ADAC产率约为93.37%。15 ℃下对目标产物表面性能测定可知,cmc为4.5×10-5 mol/L,γcmc为27.07 mN/m,有效性(πcmc)为45.99 mN/m,效率(pc20)为5.301。
