Hydrogen, a quantum gas, raises to unique problemsin the estimation of liquid properties of mixtures containing dissolved hydrogen–a problem often encountered in hydroprocessing of hydrocarbons. The liquid density and enthalpy of a hydrogen‐containing mixture in particular are not adequately described by the pseudocritical concept but are best calculated by summing the liquid partial molar quantities of hydrogen and that of hydrogen‐free liquid solvent. Liquid partial molar volumes and enthalpies of hydrogen have been evaluated and the results, including the effects of pressure and composition, presented in generalized equations. These generalized equations are shown to be useful in estimating the liquid density and enthalpy of hydrogen containing mixtures.
