松香基尾巴新型双子表面活性剂的焓熵补偿
Enthalpy-entropy Compensation of the Gemini Surfactant CsH2 s-α,ω-bis(dehydroabietyl-hydroxypropylteteramethylethylammonium Chloride)
【摘要】 为研究双子(Gemini)表面活性剂结构中疏水"尾巴"对其在水溶液中行为的影响,对以脱氢松香酰基为疏水链"尾巴"的季铵盐双子表面活性剂二氯化-N,N′-二(3-脱氢松香酰氧-2-羟丙基)四甲基乙二胺的胶团化行为进行了研究,发现焓变(ΔH)和熵变(ΔS)呈线性关系,表明其胶团化过程存在焓熵补偿现象,补偿温度为310.8 K左右,为熵驱动过程。
【Abstract】 To study the relationship between the "tail" structure and the behavior of Gemini surfactants in aqueous solution,the thermodynamic parameters of micellization of a new Gemini surfactant CsH2s-α,ω-bis(dehydroabietylhydroxypropylteteramethylethylammonium chloride),with dehydrogenated rosin as hydrophobic "tails" in the structure were investigated.When enthalpy of interaction(ΔH) was plotted against entropy(ΔS),linear plots were obtained.This indicates the clear enthalpy-entropy compensation with a compensation temperature of approximately 310.8 K.
