“…The reliability of the tie lines obtained from the experimental data was checked according to the procedure proposed by Marcilla et al (1995), recently used by Follegatti-Romero et al (2012b), Basso et al (2012) and Ansolin et al (2013). According to Marcilla et al (1995), global mass balance deviations less than 0.5% ensure the good quality of the experimental data.…”

-Phase equilibria of the reaction components are essential data for the design and process operations of biodiesel production. Despite their importance for the production of ethylic biodiesel, the reaction mixture, reactant (oil and ethanol) and the product (fatty acid ethyl esters) up to now have received less attention than the corresponding systems formed during the separation and purification phases of biodiesel production using ethanol. In this work, new experimental measurements were performed for the liquid-liquid equilibrium (LLE) of the system containing vegetable oil (sunflower oil and canola oil) + ethylic biodiesel of refined vegetable oil + anhydrous ethanol at 303.15 and at 323.15 K and the system containing refined palm oil + ethylic biodiesel of refined palm oil + ethanol at 318.15 K. The experimental data were successfully correlated by the nonrandom two−liquid (NRTL) model; the average deviations between calculated and experimental data were smaller than 1.00%.

The salting-out phase equilibria for acetone, 1-butanol, and ethanol (ABE) from dilute aqueous solutions using potassium carbonate (K 2 CO 3 ) and dipotassium hydrogen phosphate trihydrate (K 2 HPO 4 Á3H 2 O) as outstanding salting-out agents were investigated. Increasing the salt concentration strengthened the salting-out effects and improved the distribution coefficients of all three solvents (ABE) significantly. Temperature had a slight effect on the phase equilibria. The K 2 HPO 4 solution (69 wt %) showed a stronger salting-out effect than the K 2 CO 3 solution (56 wt %) on recovering ABE from dilute aqueous solutions. Dilute aqueous solutions containing more solvents increased the recoveries of acetone and 1-butanol, while the results showed a negligible effect on the solubility of ABE. The solubility of ABE was also correlated well with the molar number of salt per gram of water in the aqueous phase. A new equation demonstrated this satisfactorily.
