Abstract

This study aimed to measure the liquid−liquid equilibrium (LLE) data for a ternary (water–acetone–ethyl acetate) system to extract acetone. For this purpose, the experiments were conducted with a feed containing 80 wt.% water and 20 wt.% acetone in a T-shaped micromixer and then in a 0.8 mm microtube. The operational variables, e.g., solvent-to-feed ratio (S/F, 0.33-3.00 v/v) and operating temperature (303.15, 308.15, 313.15 and 318.15 K) were calculated at 0.1 MPa. According to the experimental results, the best selectivity (S) and distribution coefficient (D_2) were achieved at 0.50 v/v and 313.15 K. Besides, the interaction parameters were obtained for the components by fitting UNIQUAC and NRTL models to experimental data. Both models exhibited high levels of accuracy, with standard deviations in the 0.0002-0.0346 range from experimental data. The results obtained from the UNIQUAC and NRTL models were well consistent with experimental data (root mean square deviation were 0.0138 and 0.0116 for UNIQUAC and NRTL models, respectively).
