Description
Summary: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 (Vφ), the limiting partial molar volume (Vφ0), viscosity B-coefficient, Helper's constant and the free energies of activation per mole of solvent (Δμ10≠) and solute (Δμ20≠) 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. [Display omitted] •Density and viscosity of PZ + AMP + H2O solutions were studied.•Based on the basic physical data, the properties of the experimental system were studied.•Intermolecular interactions were analyzed according to volumetric and viscometric properties.
