An apparatus and procedures are described for accurate determination of both gas solubility and vapor pressure of mixed solvents. A degassing process in which a mixed solvent is degassed thoroughly while keeping the composition unchanged is examined carefully. Measurement of the vapor pressure of the solvent is made before the introduction of the gas component, which increases the reliability of gas-solubih''ty data determined later. Experimental data are presented for the vapor pressures and nitrogen solubilities of binary mixtures of cyclohexane and benzene at 25°C. Reproducibilities are ±10 Pa and ±0.1% for the vapor pressures and the solubilities, respectively.
