| 摘 要： | 以非离子型表面活性剂、甲苯、水和醇类组成微乳液。研究了醇分子从油相转移到界面相时体系的吉布斯函数变化,以及温度对吉布斯函数的影响,并由此计算出体系熵和焓的变化。可以发现,上述热力学函数的变化,与醇的碳原子数n呈线性关系:这些关系式对讨论微乳液的构成和稳定性是很重要的。 |
| 关 键 词： | 非离子型表面活性剂 微乳液 |

| Abstract: | In the four-component microemulsion (nonionic surfactant, water, toluene and alcohol) , the free energy change in transfer of alcohol from the continuous oil phase to the interfacial region is reported. The entropy and enthalpy changes due to the effect of temperature on the free energy are also reported. The effect of chain length of the alcohol is dealt with as well. It is thus shown that the thermodynamic function changes as linear functions of n, the number of carbons in the alcohol, can be described by the following relationships:These data are analyzed with respect to the microemulsion structure and stability. |
