Solubility and Liquid-Liquid Equilibrium of Aqueous Systems of Iodoethane with Methanol, Ethanol, or 1-Propanol at Temperature 298.15 K and Pressure 101.2 kPa
A study to attain the solubility and liquid-liquid equilibrium (LLE) data for the ternary mixtures of water + alcohol + iodoethane (where alcohol = methanol, or ethanol, or 1-propanol) was carried out at temperature 298.15 K and pressure of 0.1 MPa. The consistency of the binodal and phase diagram data were well ascertained by Hand and Othmer-Tobias empirical equations. The NRTL and UNIQUAC thermodynamic models were shown to yield accurate values for the LLE of the three systems. Plait point, distribution coefficient, solvent selectivity, and binary interaction parameters are reported for each ternary system. The selectivity of water for methanol in the ternary studied system is very high. The removal of methanol from the azeotropic binary system of methanol + iodoethane by means of water is potentially effective to yield pure iodoethane at ambient temperature. The immiscibility region of the system decreases significantly with increasing of the alcohol molecular chain.
