The actual significance of the so-called compensation temperature Tc for micellization of surfactants is reviewed. It is demonstrated that it is possible to obtain as many Tc values as the number of temperature intervals in which the dependencies of enthalpy and entropy changes with temperature are analyzed. The value of each Tc will be the central value To of each temperature interval. These two facts suggest that Tc is simply such experimental To. Thus any physical interpretation derived from Tc is unfounded.

分析一个古老的争议:表面活性剂胶束化的补偿温度

综述了所谓的补偿温度T c对于表面活性剂的胶束的实际意义结果表明,可以获得与温度间隔数量一样多的T c值,在该温度间隔中分析了焓和熵随温度的变化的相关性。每个T c的值将是每个温度间隔的中心值T o。这两个事实表明,T c只是这样的实验性T o。因此,从T c得出的任何物理解释都是没有根据的。
