【摘要】 以非离子型表面活性剂(Triton X-100)、十六烷、正己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。本文研究水相中不同盐类和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。更多还原

【Abstract】 This paper studied the microemulsion of TritonX-100, Hexadecane, brine （water）, hexanol system. △G_s→i⁰, the variation of the standard Gibbs function for alcohol （cosurfactant） migrating from the oil phase to the interfacial phase, was determined and discussed. △S_s→i⁰, △H_s→i⁰, the variation of the standard entropy and standard enthalpy respectively, were calculated accordingly through the thermodynamic relations and the various temperatures. The result showed that there exist linear relationship between the above thermodynamic functions and the cationic valence and pH of the brine. Based upon the above results, analysis and discussion on the stability and structure of the microemulsion were given.更多还原
