The authors have determined the thermodynamic characteristics of cyclohexanone distribution between extractants and water, making it possible to estimate the effectiveness of its separation by the extraction method. The extractants studied were hexane, heptane, octane, benzene, toluene, ethylbenzene, ethyl acetate, and butyl acetate. Analysis of the results shows that the partition ratio increases with increase of the equilibrium concentrations of cyclohexanone in the coexisting phases, indicating association of the molecules of the distributed substance in the extractant phase. The foregoing leads to the conclusion that aromatic hydrocarbons and acetate esters are superior to paraffins in extractive properties.
