摘要
以酰胺中间体和溴代烷烃反应,合成出一类新型的含酰胺基双子季铵盐阳离子表面活性剂——二溴双(N-十二(或十四、十六)烷基二甲基叔胺基)乙二酰胺,用IR、1H-NMR对其进行结构鉴定,测定其表面性能,并对其热稳定性和酸碱稳定性进行研究。结果表明,此类表面活性剂表面性能优良,具有较好的热稳定性,且在碱性溶液中易降解,具有较好的环保性能。
A new type of cationic surfactant--dibrom bi（N-dodeca alkyl dimethyl tertiary amine） ethylene diamine was synthesized by amido intermedium reaction with brominated alkane. The product structure was identified by IR and ^1H-NMR. Its surface activities, thermal stability, acid ＆ alkali stability were determined, the result shows that the surfactant has excellent surface ability and have better thermal stability. It is easy to be decomposed in alkali solvent, so it has better value in environmental protection.
