LIQUID-LIQUID EQUILIBRIUM FOR THE TERNARY SYSTEMS WATER + DMM3 + (P-XYLENE, TOLUENE, AND N-HEPTANE) AT DIFFERENT TEMPERATURES
In order to reduce the decomposition of DMM3, the DMM3 aqueous solution was separated by liquid-liquid extraction. Liquid-liquid equilibria (LLE) data for three ternary systems of water + DMM3 + p-xylene, water + DMM3 + toluene, and water + DMM3 + n-heptane were measured under atmospheric pressure at 303.15 K and 313.15 K. The results indicated that p-xylene, toluene, and n-heptane showed excellent extraction ability for separating DMM3 aqueous solution. Moreover, the LLE data were correlated by NRTL and UNIQUAC models with good agreement.
