ABSTRACT
Liquid liquid equilibrium data for quaternary systems of water + propan-1-ol + 2,2,4-trimethylpentane (TMP) + 2,2'-oxybis(propane) (DIPE) or dimethyl carbonate and ternary systems of water + propan-1-ol + TMP or DIPE or dimethyl carbonate (DMC) were measured at 298.15 K and ambient pressure. The experimental tie-line results were correlated with the modified and extended universal quasichemical (UNIQUAC) activity coefficient models both with ternary and quaternary parameters in addition to binary ones. Distribution coefficients were calculated to evaluate the solubility of DMC or DIPE in aqueous and organic phases. The phase diagrams for the ternary and quaternary systems measured in this work including both the experimental and the correlated tie lines are presented.
