Solubility of N2O in aqueous monoethanolamine and 2-(2-Aminoethyl-amino)ethanol solutions from 298 to 343 K

Abstract

The solubility of N2O in MEA and AEEA were measured at concentrations of 30 wt% and pure solutions for the temperatures between 298 and 343 K. The solubility of N2O decreases as the amine molecular weight increases in 30 wt% solutions. In pure amine solutions the trend is opposite. Solubilities of CO2 and N2O in water were also measured in the same range of temperatures. The ratio between the solubility of CO2 and that of N2O in water is dependent on temperature but an average value of 0.72 can be used.
