Liquid-Liquid Equilibrium for the Ethanol + Water + Propylene and 2-Propanol + Water + Propylene Systems from Subcritical to Near-Critical Conditions

摘要

Liquid-liqudi equilibria have been measured for hte systems ethanol + water + propylene, and 2-propanol + water + propylene, from subcritical to near-critical conditions (313-363 K), to investigate the applicability of propylene as a solvent for hte extraction of alcohols from aqueous solutions. The favorable effect of temeprature on the alcohol distribution coefficient is confirmed for both systems.
