Abstract
Phase diagrams of PPG425+Na2SO4+H2O and PPG425+(NH4)2SO4+H2O systems at 298.15 K were measured. The densities and viscosities of two-phase systems were also measured. The improved regular solution theory was used to correlate the equilibrium data. In this theory a mixing entropy term and the Fowler-Guggenheim long-range electrostatic term has been used.
