摘要：

The densities and viscosities of ternary solution of piperazine (PZ) + 2-Amino-2-methyl-1-propanol (AMP) + H2O were measured at P = 101 kPa and T = (303.15-343.15) K. The effects of temperature and concentration on the density and viscosity of ternary solution were investigated. The apparent molar volume (V-phi), the limiting partial molar volume (V-phi(0)), viscosity B-coefficient, Helper's constant and the free energies of activation per mole of solvent (Delta mu(0 not equal)(1)) and solute (Delta mu(0 not equal)(2)) were calculated from the density and viscosity, respectively. The solute-solute and solvent-solute interactions were analyzed from the volumetric and viscometric properties. The results show that the PZ has a destructive effect on the structure of mixed solvent. (C) 2020 Elsevier B.V. All rights reserved.
