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 Δη,and the excess energy of activation for viscous flow ΔG*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.
