The reduced equation of state for gases and liquids developed by Benson and Golding in 1951 is modified and used to calculate liquid enthalpy departures for saturated pure substances and mixtures. The temperature-independent coefficients in the modified equation are determined from critical properties and experimental liquid enthalpies at the boiling point and at the critical point. The results of the proposed method are compared with those predicted with the modified Redlich-Kwong equation of state by Joffe and Zudkevitch.
