摘要
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.
The microemulsion which is formed with nonionic surfactants is a quarternary mixture made of alkyl phenol oxyethylene ethers, oil(toluene), water and alcohol(hexanol). This system was studied thermo-dynamically by means of dilution to determine the standard free energy of transfer from the oil phase to the interfacial region for the cosurfa-ctant. From the effects of temperature, the entropy and enthalpy values were also calculated. The relationships between the thermodynamic quan-tities and the oxyethylene unit number (n)of the surfactants were determined as follows: △G_(s-i)~0=31300+396n-T.exp (4.85-0.00761n) (J.mo1^(-1)) △H_(s-i)~0=31300+369n(J.mol^(-1)) ln△S(s-i)~0=4.85+0.00761n
