Density and Viscosity Investigation for Binary Mixtures of Polyoxymethylene Dimethyl Ethers with 1-Propanol, 1-Butanol, and 1-Pentanol

The density and viscosity of binary mixtures of polyoxymethylene dimethyl ethers (PODEn) with three 1-alcohols (1-propanol, 1-butanol, and 1-pentanol) were investigated in this work from 303.15 to 333.15 K and at atmospheric pressure. The measurements were conducted by a vibrating-tube method for density and a capillary-tube method for viscosity. The densities and viscosities of the mixtures were correlated by the Jouyban–Acree model and McAllister four-body model, respectively. In addition, the excess molar volumes and the viscosity deviations of the mixtures were computed and correlated by the Redlich–Kister equation, and the discussion about the excess molar volumes and viscosity deviations was carried out.
