Solubility of hydrogen, carbon monoxide, and 1-octene in various solvents and solvent mixtures

The solubility of H<SUB>2</SUB> has been measured as a function of pressure in ethanol + water and various solvents at (298 and 323) K. The results are compared with theoretical predictions for H<SUB>2</SUB> in different solvents and some mixtures and found to agree within &#177; 10% error, except for acetonitrile. The solubility of CO in 1-octene has also been measured. Liquid-liquid equilibrium for the 1-octene + water + ethanol system was measured at (298 and 323) K, but the predictions of these data by the UNIFAC-UNIQUAC models were not found to be satisfactory, except for higher 1-octene concentrations in water (&gt;6% w/w) for which the predictions were within 10% error
