PARTIAL MOLAL VOLUME OF CARBON DIOXIDE IN WATER SOLUTIONS

The specific volumes of carbon dioxide-water solutions were measured in a visual cell, in the range of 0° to 40° C. and 15 to 500 p.s.i.a. From these measured volumes and published solubility data, the partial molal volumes of carbon dioxide in water were calculated. The experimental values were compared with the predictions of the Krichevsky-Kasarnovsky equation and the correlation of Lyckman, Eckert, and Prausnitz. The latter gave good agreement with the experimental data; the former, poor agreement. © 1969, American Chemical Society. All rights reserved.
