ABSTRACT

Extraction followed by heterogeneous azeotropic distillation is an effective and energy-saving method to separate acrylic acid from aqueous solution. In this work, the liquid liquid equilibria data for the system of water + acrylic acid + cyclopentyl methyl ether at three temperatures were determined at 100.249 kPa. The reliability of the liquid liquid equilibria data was ascertained by using Hand and Othmer Tobias correlations. The separation factors of cyclopentyl methyl ether at different temperatures were compared. NRTL and UNIQUAC models were used to correlate the liquid liquid equilibria experimental data. Moreover, a comparative study on the three solvents, including cyclopentyl methyl ether, isobutyl ethanoate, and 4-methyl-2-pentanone, was made in terms of basic physical properties and extraction ability.
