| Popis: | Liquid-liquid equilibrium data for water + acetic acid + {ethyl or butyl or isobutyl of isoamyl or heptyl acetate} systems at T = {293.2 and 313.2} K and atmospheric pressure (P ≈ 95 kPa) were determined by density and refractive index measurements. Binodal curves were constructed utilizing cloud point method and tie lines were determined using equations obtained through cloud point data fit. Partition coefficients, ester selectivities and percent of extraction were calculated in order to compare the solvents employed. It was verified that immiscibility region increases in the order: ethyl |
