摘要：

A vacuum desolubilization method with chromatographic analysis of the resulting gas phase for the determination of gas solubilities in pure and mixed solvents is described. Its application to the solubility of carbon dioxide in a series of aprotic organic solvents, alcohols, and water, as well as in mixtures of these solvents, shows that reliable data can thus be obtained with an accuracy of a few percent. It possesses the advantage over the direct injection method (which was extended to solvent mixtures is the present study) to yield absolute values and to reach lower solubilities.
