Density, Viscosity, Solubility, and Diffusivity of N₂O in Aqueous Amino Acid Salt Solutions

Abstract

Solubility and diffusivity of N2O in aqueous solutions of potassium taurate are reported over a wide range of concentration and temperature. Also, the solubility of N2O in aqueous potassium glycinate solution is reported at 295 K. The ion specific constants, based on the model of Schumpe,5,6 are reported for taurate and glycinate anions. A modified Stokes−Einstein relationship is proposed for the diffusivity of N2O in aqueous potassium taurate solution in the temperature range 293−308 K.
