“…We have measured the capillary constant and calculated the surface tension of methane-helium (Baidakov and Grishina, 2013), ethane-helium (Baidakov and Sulla, 1995), and propane-helium, and also methane-hydrogen (Baidakov et al, 2017a) and ethane-hydrogen (Baidakov et al, 2017b) solutions. For methane-helium system, new values of surface tension were calculated with the use of recalculated density data.…”

The differential capillary method has been used to measure the capillary constant a 2 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 4 MPa. Equations have been suggested which describe the temperature, baric, and concentration dependences of a 2 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.
