Abstract Different microscopic and thermodynamic properties like the resonance light scattering intensity, microenvironment 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.

{水+叔丁醇}和{水+叔丁醇+异丁醇}溶液中的热力学性质和结构转变

摘要 精确测量了不同的微观和热力学性质，如共振光散射强度、微环境极性、{水+TBA}二元溶液的密度和热容量以及{水+TBA+IBA}三元溶液的密度。通过微观和热力学性质的分析，研究了不同组成的TBA水溶液和{水+TBA+IBA}三元溶液中醇-水聚集体的形成和结构转变。结果表明，水溶助长剂溶液中的精细结构转变可以通过热力学性质的变化得到很好的反映，这为深入了解水溶助长剂水溶液中的结构变化提供了一种有效的方法。
