Solubility of carbon dioxide in mixtures of 2-amino-2-methyl-1-propanol and organic solvents

This paper presents experimental data on the solubility of CO2 in solutions of AMP in one of two organic solvents: N-methyl-2-pyrrolidone or triethylene glycol dimethyl ether, at different amine concentrations (15 wt% and 25 wt%) and temperatures (25 °C and 50 °C). A solid precipitate was observed during some of the experiments. The absorption capacity of the solution increased with AMP concentration and was higher at lower temperatures.
