SURFACE TENSION OF ALKANES SATURATED WITH HELIUM OR HYDROGEN
RÉSUMÉ
The differential capillary method has been used to measure the capillary constant a2 and to determine the surface tension σ of alkanes (methane, ethane, propane) saturated with helium or hydrogen. Experiments have been made in temperature ranges from the triple-point temperature to temperatures close to the solvent critical point at pressures from that of saturated vapors of a pure liquid to 4MPa. Equations have been suggested which describe the temperature, baric, and concentration dependences of a2 and σ of solutions. The data obtained have been used to calculate the relative adsorption. The results of measurements are discussed in the framework of thermodynamic models of the theory of surface phenomena.
