文摘

Tie-line phase compositions were experimentally determined for three quaternary systems of water + methanol + diethyl carbonate + methylbenzene or heptane or cyclohexane and one related ternary system of water + diethyl carbonate + methylbenzene at 298.15 K and atmospheric pressure. The experimental tie-line data were correlated using the modified and extended UNIQUAC activity coefficient models. Furthermore, the effect of hydroxyl group on the solubility of alcohols in the two phases was compared.
