Abstract
The density and speed of sound of the solutions of poly(propylene glycol) 400, in ethanol and 2-propanol at T = (288.15 to 328.15) K, and dynamic viscosity of these solutions at T = (298.15 to 328.15) K have been measured experimentally over the entire range of compositions and atmospheric pressure. From these experimental data, the excess molar volume, VmE, excess molar isentropic compression, κEs,m, and deviation of logarithm of viscosity, Δ ln η, have been determined for each composition. VmE, κEs,m, and viscosity data have been adequately fitted to the Redlich−Kister and NRTL models.
