摘要：
Densities of the binary and ternary systems formed by mixtures of bis(2-hydroxyethyl)amine (DEA) + water, DEA + methanol (MeOH), DEA + ethanol (EtOH) and DEA + MeOH + water, DEA + EtOH + water were measured at atmospheric pressure for the whole composition range at temperatures from 278.15 K to 353.15 K using an Anton Paar digital vibrating U-tube densimeter (model DMA 5000M). The excess molar volumes have been calculated from the experimental densities in this work and correlated using the Redlich-Kister equation. A set of parameters for the Redlich-Kister equation has been determined to represent the density of the liquid mixture. (C) 2012 Elsevier B.V. All rights reserved.
