ResumoThe phase separation in the liquid binary system of neon and normal hydrogen has been investigated by measuring the specific heat at saturation for different compositions between 24 K and 30 K. The phase-separation curve has been determined. The coordinates of the upper critical consolute point are Tc = 28.93 K and χH2 = 0.308. The temperature at which the liquid phase-separation curve meets the freezing curve is TM = 24.27 K. The excess enthalphy, the excess entropy and the excess Gibbs function of the liquid mixture have been calculated as functions of temperature and composition. The vapour correction for heat-capacity measurements of a two-component liquid-vapour system is discussed.
