Solubility of Hydrogen, Carbon Monoxide, and 1-Octene in Various Solvents and Solvent Mixtures

Abstract

The solubility of H2 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 H2 in different solvents and some mixtures and found to agree within ±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 (>6% w/w) for which the predictions were within 10% error.
