Vapor−liquid equilibrium (VLE) data for the systems CO2/H2/acetonitrile, CO2/H2/acetone, and CO2/H2/methanol were determined at 40 °C and 25, 60, and 90 bar. A variable volume view cell was used coupled with an online gas chromatograph. The solubility of H2 in expanded solvents was improved by the p...
