Abstract

Physical solubility and diffusivity of N2O and CO2 in pure water and of N2O in aqueous sodium glycinate solutions of mass fraction (0.1 to 0.5) were measured at T = (303.15 to 323.15) K. Since it was not possible to measure these properties for CO2 due to the chemical reaction between CO2 and the amine group of sodium glycinate, these were estimated using the well-known N2O analogy. While the physical solubility increases with a decrease in temperature and with a decrease in mass fraction, diffusivity decreases with a decrease in temperature as well as an increase in mass fraction except for concentrated solution (mass fraction 0.4 and 0.5) where it increases with a decrease in temperature.
