Excess Molar Volume and Viscosity Deviation for the Binary Mixture of Diethylene Glycol Monobutyl Ether + Water from (293.15 to 333.15) K at Atmospheric Pressure

Abstract

Densities and viscosities have been measured as a function of composition for the binary liquid mixture of diethylene glycol monobutyl ether CH3(CH2)3O(CH2)2O(CH2)2OH + water 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 Ubbelohde capillary viscometer. From the experimental data, the excess molar volumes VE and viscosity deviations δη were calculated. This binary system shows negative deviations in excess molar volumes from the ideal behavior. Excess molar volumes and viscosity deviations were correlated by the Redlich−Kister type equations to obtain their coefficients and standard deviations.
