Abstract: The solubility of carbon monoxide in phenol+ethanol mixed solvents at elevated pressures is reported in this article.The experimental results revealed the influence of pressure on the solubility of CO in phenol+ethanol mixtures.These mixtures are a poorer solvent for carbon monoxide.The solubility of CO is a linear function of pressure,and the extended Henry's constants were presented at different concentrations of phenol.The cubic Soave-Redlich-Kwong equation of state was used to correlate the experimental gas liquid equilibrium data and to predict the solubility of CO.At the same time,the binary interaction parameters,kij,for CO-phenol,CO-ethanol and phenol-ethanol systems were estimated by fitting experimental GLE data at 303.15 K and at 2.0-9.0 MPa.Hence,a model was suggested for the solubility of CO in phenol+ethanol mixed solvents.The agreement between experimental and calculated solubilities with the proposed model was rather satisfactory.

Key words: solubility, gas-liquid equilibrium, carbon monoxide, phenol, ethanol
