GAS-LIQUID EQUILIBRIUM IN MIXTURES OF HYDROGEN + META-XYLENE AND + META-CRESOL

Gas-liquid equilibrium has been determined for two binary mixtures of hydrogen: with m-xylene and with m-cresol. A flow apparatus was used to reduce residence time of the fluids in the apparatus, thus making possible measurement at elevated temperatures without causing significant thermal decomposition of the organic compounds. Experimentally observed compositions of the gas and liquid mixtures are reported at four temperatures from 462 to 582 K for hydrogen + m-xylene, and at six temperatures from 462 to 662 K for hydrogen + m-cresol. At each temperature observations were made at seven pressures from 2 to 25 MPa. Vapor pressures of the solvents at the reported temperatures were also measured. © 1979.
