Liquid Liquid Extraction of Cyclopentanone from Aqueous Solution with Methylcyclohexane or Propyl Acetate at Different Temperatures

Our research extends the knowledge into the liquid-liquid extraction regarding ternary mixtures of water + cyclopentanone + extractants (methylcyclohexane and propyl acetate) at 308.2, 318.2, and 328.2 K and 101.3 kPa. The extracting capabilities of the selected extractants were explored when it came to the distribution coefficient and selectivity on the basis of the liquid-liquid equilibrium values, while the consistency of the dependability of the tie-line values was corroborated utilizing both the Bachman and Hand empirical equations. In addition, the binary interaction energy parameters of the compounds were achieved by two classic activity coefficient models (i.e., NRTL and UNIQUAC); satisfactory results were yielded with all the fitting root-mean square deviations (rmsd %) <= 0.71.
