摘要：

This work reports new measurements of densities and viscosities for the binary liquid mixture of triethylene glycol monobutyl ether (CH(3)(CH(2))(3)(OCH(2)CH(2))(3)OH) + water as a function of composition in the temperature range from (293.15 to 333.15) K at atmospheric pressure. Densities were determined using a capillary pycnometer. Viscosities were measured with an Ubbelohde capillary viscometer. From the experimental data, the excess molar volumes, V(E) and viscosity deviations, delta eta, were calculated. Both excess molar volumes and viscosity deviations were correlated by the Redlich-Kister-type equations. The results suggest that the molecular interaction between triethylene glycol monobutyl ether and water is stronger than that of diethylene glycol monobutyl ether and water.
