| Abstract: | Densities and viscosities were measured as a function of composition for binary liquid mixture of diethylene glycol monoethyl ether CH_3CH_2O(CH_2)_2O(CH_2)_2OH] + water from 293.15 to 333.15 K at atmospheric pressure, with a capillary pycnometer and Uhbelohde capillary viscometer respectively. From the experimental data, the excess molar volume V~E, viscosity deviation △η, and the excess energy of activation for viscous flow △G~(*E) were calculated. These data were correlated by the Redlich-Kister type equations to obtain the coefficients and standard deviations. The results showed a strong molecular interaction between diethylene glycol monoethyl ether and water. |
