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

Abstract

Solubility and diffusivity of N 2 O in aqueous solutions of potassium taurate are reported over a wide range of concentration and temperature. Also, the solubility of N 2 O 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 N 2 O in aqueous potassium taurate solution in the temperature range 293−308 K.
