摘要：

Different microscopic and thermodynamic properties like the resonance light scattering intensity, micro-environment polarity, the density and heat capacity of {water+ TBA} binary solution and the density of {water+ TBA+ IBA} ternary solution were precisely measured. Formation and structure transitions of alcohol-water aggregate in TBA aqueous solution and {water+ TBA+ IBA} ternary solutions at different compositions were investigated by analysis of both microscopic and thermodynamic properties. It is indicated from the results that the fine structure transitions in hydrotrope solutions can be well reflected by the variance of thermodynamic properties, which provides an efficient way to give deeper insight into the structure changes in aqueous hydrotrope solutions.
