ABSTRACT

Accurate LLE data are of momentous significance for the design, emulation and optimizing of extractive process. For assembling the essential data of the operation about extracting cyclohexanol from aqueous solution, LLE data for {Water + Cyclohexanol + Toluene}, {Water + Cyclohexanol + p-Xylene} and {Water + Cyclohexanol + Mesityl Oxide} ternary systems were experimentally determined at 303.15 K and 323.15 K under atmospheric pressure. The solvents separating power was assessed with distribution coefficient and selectivity. Consistency of experimental data was confirmed with Othmer-Tobias and Bachman equations. The LLE data were also correlated with NRTL and UNIQUAC models, the regression result was better with RMSD values were all less than 0.2%. However, UNIQUAC model correlated better since the RMSD was smaller. In addition, relevant binary interaction parameters were generated during correlation process.
