在恒压和摩尔分数下，测定了高级醇水溶液的表面张力与温度的关系。对于所有研究的醇，在足够高的浓度下，σ（T）曲线中获得最小值，该最小值似乎不能用溶解度增加来解释。按照第一部分中概述的程序计算不同温度下的可逆吸附（或延伸）热。在这个最小值处，表面积可逆扩展的热消失了。
The surface tension of aqueous solutions of higher alcohols is measured as function of temperature at constant pressure and mole fraction. For all the studied alcohols a minimum in the σ (T) curves is obtained for sufficiently high concentrations, which minimum seems not to be explained by a solubility increase. The heat of reversible adsorption (or extension) is calculated for different temperatures following the procedure outlined in part I. The heat of reversible extension of the surface area vanishes at this minimum.
