Density, Viscosity, and N2O Solubility of Aqueous 2‑(Methylamino)ethanol Solution

In the present work, the density and viscosity of 2-(methylamino)­ethanol (MAE) solution were measured over the temperature range of 293.15 to 323.15 K with MAE mass fractions of w 1 = 0.075, 0.15, 0.225, and 0.30 and CO2 loadings varying between 0 and 0.677 mol CO2/mol MAE. The physical solubility of N2O in aqueous MAE solution was measured in a stirred cell reactor over the temperature range of 289.31–348.18 K with MAE mass fraction w 1 = 0.075, 0.15, 0.225, 0.30, 0.375, 0.45, 0.60, 0.75, and 1. The experimental density data for both CO2 loaded and unloaded aqueous MAE solutions were fitted by Redlich–Kister equation. The Weiland’s model was used to correlate the viscosity data of aqueous MAE solution. Finally, N2O solubility data were correlated by using an empirical polynomial model and compared with both the semiempirical model and the Redlich–Kister equation.
