Method/Apparatus/Procedure:
A glass apparatus was employed in which the uptake of gas by a known volume of solvent in a dissolution cell was volumetrically determined. The gas was displaced by mercury as the gas dissolved at constant pressure. A magnetically operated gas circulating pump and bubbling tip were provided for bubbling the gas through the solvent in the dissolution cell.

(1) Although not specifically stated in the paper, it is assumed that the mole fraction solubility, x, is for a total pressure of 101.325 kPa.
(2) The solubility corresponding to a gas partial pressure of 101.325 kPa was calculated by the compiler; Raoult's law was assumed to apply to the mixed solvent solution.
(3) Triethanolamine in mixed solvent
