ABSTRACT
Liquid-liquid equilibria (LLE) data for (dimethyl carbonate (DMC) + 2-methyl-1-propanol + water) and (DMC + 2-methyl-2-propanol + water) systems were accurately determined using jacketed equilibrium cell under atmospheric pressure at 303.15 and 313.15 K. The experimental data were found to be consistent with Bachman-Brown correlation. The data were correlated well using the Non-Random Two Liquid (NRTL) and Universal Quasi-Chemical (UNIQUAC) activity coefficient models with root-mean-square deviations (RMSD) between the experimental and calculated phase compositions of 0.004 and 0.002 for the DMC + 2-methyl-1-propanol + water system, 0.003 and 0.005 for the DMC + 2-methyl-2-propanol + water system, respectively. The effect of temperature to phase boundary was observed as well.
