Liquid–Liquid Equilibria for the System Water + 1,3-Dichloro-2-propanol + Epichlorohydrin from (283.2 to 303.2) K

Abstract

Liquid–liquid equilibrium data for the ternary system of water + 1,3-dichloro-2-propanol + epichlorohydrin were determined at the temperature of (283.15, 293.15, 303.15) K and atmosphere pressure. The reliability of experimental method was examined by the mass balance verification and the Othmer–Tobias equation. The experimental data were successfully correlated with both the NRTL model and UNIQUAC model, and the NRTL model presents more satisfactory result. These LLE data and model parameters obtained in this work are helpful for understanding, designing, and developing epichlorohydrin synthesis processes.
