Density and Viscosity of the Binary Mixture of Triethylene Glycol Monobutyl Ether + Water from (293.15 to 333.15) K at Atmospheric Pressure

摘要

This work reports new measurements of densities and viscosities for the binary liquid mixture of triethylene glycol monobutyl ether (CH3(CH2)3(OCH2CH2)3OH) + 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, δ_η, 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 diefhylene glycol monobutyl ether and water.
