Abstract
We presented the results of measuring of the capillary constant of isobutane–hydrogen solution in the temperature range of 298.15–348.15 K at pressures from the saturation pressure of pure isobutane up to 4 MPa. The surface tension of the solution was determined. The equations approximating the concentration and pressure dependences of the capillary constant and surface tension are constructed.
