An apparatus is described for measuring gas solubilities at high pressure for gases of moderate to high solubility. Solvent, supplied by a metering pump, is continuously saturated with gas as it flows down a spiral rod. Gas is continuously supplied by means of a calibrated piston pump to provide a constant pressure. The solubility is determined from the relation between the solvent rate and the gas consumption required to achieve saturation. The solubilities of two chemically reactive gases, propene and isobutene, are reported for the solvents n ‐butanol, chlorobenzene and n ‐octane for three temperaturres, 298, 323 and 343 K, and a range of pressures from 0.2 to 1.9 MPa.
