非离子型表面活性剂所组成的微乳液是由水,甲苯,正已醇和聚氧乙烯苯醚所构成,用加溶作用法求醇从油相转移到界面相时的吉布斯函数的变化,以及温度对它的影响.从而可得出该过程的熵和焓的变化.这些热力学性质与表面活性剂的氧乙烯基团数n呈以下关系:△G_(s-i)~0=31300+396n-T·exp(4.85+0.0076n)(J·mol~(-1))△H_(s-i)~0=31300+396n(J·mol~(-1))ln(△S_(s-)~0=4.85+0.0076n
The microemulsion consisting of nonionic surfactant consists of water, toluene, n-hexanol and polyoxyethylene phenyl ether. The solubilization method is used to determine the Gibbs function of alcohols when they are transferred from the oil phase to the interfacial phase , And the effect of temperature on it, thus the entropy and enthalpy change of the process can be obtained.These thermodynamic properties are related to the number of oxyethylene groups n of the surfactant as follows: △ G_ (si) ~ 0 = 31300 + 396n -T · exp (4.85 + 0.0076n) (J · mol -1) △ H_ (si) ~ 0 = 31300 + 396n (J · mol -1) ln (△ S_ 0 = 4.85 + 0.0076n
