ABSTRACT

Physicochemical properties such as density and viscosity of aqueous novel bis(3-aminopropyl)amine (APA) and an aqueous novel blend of N-methyldiethanolamine (MDEA) and APA solutions as well as solubility and diffusivity of N2O into these binary and ternary solutions were measured from temperature T = 298 to 323 K at atmospheric pressure. In this study, experiments cover the molality range for APA = 0 1.291 mol*kg 1 and MDEA = 2.915 4.416 mol*kg 1. The diffusivity and solubility experiments were conducted with a wetted wall column absorber and Corning glass equilibrium cell, respectively. The experimental binary and ternary density data as well as binary viscosity data were correlated by Redlich Kister equation whereas ternary viscosity data were correlated by the Grunberg and Nissan model. On the other hand, solubility and diffusivity were correlated with different models. All of the correlations based on the different model performed are capable of adequately predicting experimental physicochemical data.
