Abstract: The density of the quaternary mixture water + methanol + ethanol + propan-2-ol and its four ternary and six binary subsystems is measured over a wide composition range at ambient temperature and pressure, that is, 298.15 K and 0.1 MPa. The resulting molar volume data are correlated with a response surface model, consisting of linear, quadratic, bilinear, and trilinear interaction terms. The density values obtained with this correlation are compared to molecular simulation results and experimental literature data. Further, the excess molar volume and the partial molar volumes are determined for the ternary and quaternary mixtures. The analytical solution for the partial molar volumes of a quaternary mixture for the response surface model is also given.
