ABSTRACT

Liquid-liquid equilibrium (LLE) data for the ternary system water + 2-methyl-1-propanol + butyl acetate and water + 2-methyl-2-propanol + butyl acetate were measured at the temperature T = (298.15 and 323.15) K and under atmospheric pressure, respectively. Both the Othmer-Tobias and Bachman equations were used to test the reliability of the experimental data. Moreover, the NRTL and UNIQUAC activity coefficient models were applied to correlate the determined data, and the result showed that the UNIQUAC and the NRTL models both could correlate the two systems studied well at the same conditions. In addition, distribution ratios and separation factors in the two ternary systems were calculated using the equations from the experimental liquid-liquid equilibrium data and discussed in detail.
