Density, Viscosity, and Excess Properties for Binary Mixture of Diethylene Glycol Monoethyl Ether + Water from 293.15 to 333.15 K at Atmospheric Pressure

submitted by BlaRoss 3 years and 4 months ago - Topic: Chemical Engineering

Densities and viscosities were measured as a function of composition for binary liquid mixture of diethylene glycol monoethyl ether [CH3CH2O(CH2)2O(CH2)2OH] + water from 293.15 to 333.15 K at atmospheric pressure, with a capillary pycnometer and Ubbelohde capillary viscometer respectively. From the experimental data, the excess molar volume VE, viscosity deviation In, and the excess energy of activation for viscous flow IG*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.
