Preparation,Characterization and Properties of Novel Cationic Gemini Surfactants with Rigid Amido Spacer Groups

A series of novel cationic gemini surfactants with rigid amido groups inserted as the spacers, named C ₁₂ ‐PPDA‐C ₁₂ , C ₁₄ ‐PPDA‐C ₁₄ and C ₁₆ ‐PPDA‐C ₁₆ , were synthesized by a two‐step reaction with dimethyl terephthalate, N,N‐dimethyl propylene diamine and alkyl bromide as raw materials. The chemical structures of the prepared compounds were confirmed by IR, ¹H and ¹³C NMR and element analysis. Surface activity properties of the synthesized compounds were investigated by surface tension, electrical conductivity and fluorescence. Increasing the number of carbon atoms in the hydrophobic alkyl chain, decreased the critical micelle concentration (CMC), surface tension at the CMC and the minimum surface area. Other relevant properties including foaming ability and emulsion stability were investigated. The results indicated that the synthesized gemini surfactants possess good surface properties, emulsifying properties and steady foam properties.

芥子酰胺丙基甜菜碱变粘酸化液研究

简介了两性表面活性剂芥子酰胺丙基甜菜碱(SAP-BET)的合成及其酸液变粘原理,实验考察了变粘特性。模拟酸液中SAP-BET浓度为体积分数,酸浓度为质量分数,表观粘度(AV)为170 s-1测定值。在25℃、50~1700s-1范围,15%盐酸中SAP-BET浓度≤2%时为牛顿流体,≥3%时为假塑性流体,加入6%SAP-BET时25℃的上行和下行流变曲线重合,100℃时不重合。在25~120℃范围,含6%SAP-BET的15%~28%盐酸粘(AV)温曲线在~75℃时有最大值,酸浓度的影响不大。6%SAP-BET乏盐酸pH升至1.3时,AV急剧上升至>200 mPa.s,pH继续升高时大体维持不变,温度(25~120℃)的影响不大;pH=4.0的乏盐酸在25~150℃范围的粘(AV)温曲线在~75℃时有最大值,SAP-BET浓度越高则AV越高。6%甲酸 6%~18%盐酸 1%~7.5%SAP-BET混合酸液的乏酸液(pH=4.0),100℃下的AV随SAP-BET浓度增大而显著增大,随盐酸浓度增大而略为增大;12%盐酸 3%~12%甲酸 7.5%SAP-BET混合酸的乏酸液,pH升至0.8~1.3时100℃下的AV急剧增大并大体维持不变,所达到的AV值低于相应的盐酸乏酸液,随甲酸浓度增大而减小,甲酸浓度为3%~6%时超过200 mPa.s。Fe3 (>0.5%)和互溶剂严重影响SAP-BET的功能。推荐6%SAP-BET 15%~28%盐酸体系为碳酸盐岩地层酸化用的变粘酸,7.5%SAP-BET 12%盐酸 6%甲酸体系为砂岩地层酸化时土酸的分流酸。图10参4。
