文摘
The recent empirical correlation for surface tension is further investigated for universality. C5-C8 liquidhydrocarbons, for which accurate surface tension data over the complete liquid range are available, areused. Functional reduced surface entropy is derived, which is in the general form of Trouton's rule. It ischaracterized by the critical exponent of surface tension and is valid with the unique value 0.9990 at anytemperature from freezing to the critical temperature of the liquid hydrocarbons. The relation to thegeneric nature of surface entropy is pursued.
