Abstract

(Graph Presented) 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 nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) activity coefficient models with a root-mean-square deviation (RMSD) between the experimental and calculated phase compositions of 0.004 and 0.002 for the DMC + 2-methyl-1-propanol + water system and 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.
