摘要：The density and viscosity of the pure monoethylethanolamine (EMEA), diethylethanolamine (DEEA), H2O components and the binary EMEA (1) +DEEA (2) and EMEA (1) +H2O (2) mixtures were measured from (293.15-333.15) K. The physical and thermodynamic properties of excess molar volume (V-E), thermal expansion coefficient (alpha), viscosity deviation (Delta h), activation enthalpy (Delta H), activation entropy (Delta S) and activation molar Gibbs free energy (Delta G) were calculated. The density and viscosity of the pure components as well as the binary mixtures decreased with temperature increasing. The density and viscosity of EMEA, DEEA and H2O followed the orders of H2O > EMEA > DEEA and EMEA > DEEA > H2O, respectively. The density and viscosity decreased with DEEA concentration increasing for EMEA (1) +DEEA (2). In EMEA (1) +H2O (2), the density increased with H2O concentration increasing, while the viscosity increased and then decreased with H2O concentration increasing. (C) 2016 Elsevier B.V.
