Physical properties of aqueous solutions of potassium l-prolinate from 298.15 to 343.15 K at atmospheric pressure

In this paper, experimental physical properties such as density, refractive index, and viscosity of aqueous potassium l-prolinate (KPr) as a solvent for CO2 capture were investigated. Different concentrations of aqueous KPr in terms of mass fractions (0.05, 0.10, 0.20, 0.30, and 0.40) were studied o...
