JAUREGUI-HAZA, U. J.; PARDILLO-FONTDEVILA, E. J.; WILHELM, A. M.  e  DELMAS, H.. Solubility of hidrogen and carbon monoxide in water and some organic solvents. Lat. Am. appl. res. [online]. 2004, vol.34, n.2, pp.71-74. ISSN 0327-0793.

The solubility of hydrogen and carbon monoxide in water, octene, toluene and nonanal in the range 298-373 K and 0.5-1.5 MPa was studied. The experimental values of the solubility of H2 and CO at 353 K, 363 K and 373 K were determined by the absorption method as a function of gas pressure in the solvents. The estimation of solubility of gases in water and organic solvents was also accomplished. The proposed method is based on the theory of Regular Solutions by the correlations of Prausnitz- Shair and Yen-McKetta corrected by Lemcoff factor for polar solvents. The critical temperature was predicted by Group Interaction Contribution approach. The experimental results were compared with theoretical prediction of solubility and found to agree with an average relative error of 2.6 %.
