| Abstract: | The microemulsion is composed of imidazolinium surfactant, oil(n-hexadecane), water and alcohol.The systems were studied thermodynamically by means of dilution to determine the standard free energy for alcohol to tranfer from oil phase in the interfacial region.From the effects of temperature, the entropy and enthapy were calculate.The effect of chain length is described. It is found that the thermodynamic functions change linearly with the increase of the number of carbon (n) in the alcohol.The relationship between the thermodynamic quantities and the alkyl chain length of the surfactant was determined. |
