| 摘 要： | 用微量滴定法测定了苯甲醇、正戊醇、正己醇、正庚醇、正己烷、苯、甲苯、正庚烷和四氯化碳在3-烷氧基-2-羟丙基三甲基氯化铵(RnTAC，n=8，12，14，16)胶束溶液中的增溶量．研究发现，表面活性剂碳链越长，对有机物的增溶量越大，苯甲醇在R16TAC溶液中的增溶量最大，为1．125mol／L．有机物从水相到胶束相的相转移自由能与其本身的极性和RnTAC的碳氢链长有关，极性越小、表面活性剂的碳氢链越长，增溶越容易。

| Abstract: | The solubilization of benzyl alcohol,n-pentanol,n-hexanol,n-heptanol,n-hexane,benzene,toluene,heptane and carbon tetrachloride in the aqueous solutions of 3-alkoxyl-2-hydroxylpropyltrimethyl ammonium chloride (R_nTAC) have been studied by microtitration method. The experimental results show that the length of hydrophobic chains of surfactant and the polarity of organic compound affect on the solubilized amount and the transfer free energy change from aqueous to micelle phase.The longer the hydrophobic chain of R_nTAC and the less the polarity of organic compound,the easier for it to transfer from aqueous phase to micelle phase. |
