| 摘 要： | 以非离子型表面活性剂(Triton X-100)、十六烷、正已醇和水所组成的微乳液,研究醇从油相向界面层转移时的体系Gibbs函数变化,并从热力学关系式得出焓和熵的变化关系.本文研究了相中不同盐类和PH值对这些热力学函数的影响,发现这些热力学函数与盐类中阳离子价数和PH值都呈线性关系.

Thermodynamics of microemulsion on the nonionic microemulsion Ⅲ e- ffects of brine and PH |

| Abstract: | The free energies of transfer were calculated for alcohol cosurfactant between oil and interfacial phases in Triton X 100-hexadecane-brine(aq. NaCl, BaCl2, or LaCl3)-hexanol systems. The entropies and heats of transfer were calculated from the corresponding free energies. Linear relations are found between the thermodn. parameters and the brine cation valence and pH. These results are used to discuss microemulsion structure and stability. |
