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 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.
