The literature on the thermophysical properties for fluid mixtures of the water+ammonia system has been retrieved, and the experimental data on the vapor-liquid equilibrium and thermodynamic properties were collected. The available equations of state for the present system were evaluated by means of the comparison with these experimental data. We recommend that the equation of state proposed by Ziegler and Trepp be used for calculating the thermodynamic properties and the vapor-liquid equilibrium for the water+ammonia mixtures in the range of temperatures and pressures up to about 450K and 5MPa.
