| Abstract: | Excess molar volumes (VEm) and viscosities (η) have been measured for ethylene glycol monoisopropyl ether + water from 298.15 to 318.15 K at 10 K intervals. The excess volumes are negative while viscosities are positive over the entire composition range for the system studied. and temperature has no appreciable influence on excess volumes. The observed negative VEm values are compared with the available published results at 298.15 K. Densities (ρ) and deviations in viscosity (Δη)) of the mixtures have been calculated from the results. The deviations in viscosity values are positive over the entire range of mole fractions and temperatures. The results of excess molar volume and deviations in viscosity are fitted to the Redlich-Kister relation to estimate the adjustable parameters and standard deviations. |
