Popis:	Density and viscosity for binary mixtures of diethylene glycol monobutyl ether (DEGMBE) with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) have been measured as a function of composition from (293.15 to 333.15) K at intervals of 10 K under ambient pressure. Densities were measured with a capillary pycnometer. Viscosities were determined using capillary viscometers of the Ubbelohde type. Excess molar volumes VE and viscosity deviations Δη were calculated from the experimental results and correlated by the Redlich–Kister type equations to derive the coefficients and standard deviations. The values of VE and Δη are both negative over the entire range of mole fraction which indicates that molecular interaction of MEA, DEA, and TEA through the hydrogen bond become weaker in the presence of DEGMBE.
