摘　　要：以无水哌嗪、氯乙酰氯、长链叔胺为原料合成含哌嗪和酰胺基季铵盐双子表面活性剂(I_(10),I_(12),I_(14),I_(16))。利用FTIR和^(1)H-NMR对目标产物结构进行表征。通过电导率法测定了目标产物在25℃的临界胶束浓度(CMC),计算了热力学参数ΔG^(0)_(m)。用吊环法测定了25℃时目标产物的表面张力(γ),计算了相关的表面性能参数(Γ_(max),A_(min),pC_(20),π_(CMC)),并探讨了目标产物的泡沫性能和乳化性能。结果表明,该系列表面活性剂具有较好的表面活性,泡沫稳定性达到90%以上。I_(12)乳化性最好,分出10 mL水所用的时间为883 s。A series Gemini surfactants(I_(10),I_(12),I_(14),I_(16))containing piperazine and amide bond were synthesized by using piperazine,chloroacetyl chloride,long alkyl chain primary amine,as main raw materials.The structures of products were characterized by FTIR and^(1)H-NMR.The critical micelle concentrations(CMC)of the products were measured by electrical conductivity method and the thermodynamic parameterΔG^(0)_(m)were calculated at 25℃.The surface tensions(γ)were determined by ring method and related surface properties parameters(Γ_(max),A_(min),pC_(20),π_(CMC))were calculated at 25℃.The foaming properties and emulsifying properties were investigated.The results showed that the surfactants had preferable surface activity,and the foam stability of reaches 90%.I_(12)had the significant emulsifying ability,and the emulsification time was 883 s.
