SURFACE-TENSION OF NORMAL PENTANE, HEXANE, HEPTANE, AND OCTANE

New experimental results are reported for the surface tension of normal pentane, hexane, heptane, and octane. The data were obtained with a differential capillary-rise method and cover the entire liquid range from the triple-point temperature to the critical temperature. Equations for calculating th...

Beschreibung
Zusammenfassung:	New experimental results are reported for the surface tension of normal pentane, hexane, heptane, and octane. The data were obtained with a differential capillary-rise method and cover the entire liquid range from the triple-point temperature to the critical temperature. Equations for calculating the surface tension of these n-alkanes as a function of temperature are presented.
