ABSTRACT

Liquid-liquid equilibria (LLE) data were determined for four ternary systems of water + alcohol + methoxycyclopentane (CPME); the alcohols used were methanol, ethanol, 1- propanol, and 2-propanol. All measurements were performed at 298.15 K and atmospheric pressure. Binodal curves were experimentally determined using both the cloud point method and tie-lines. The reliability of the tie-line data were verified by the Hand and Othmer-Tobias plots. Distribution coefficients and separation factors were determined from the tie-line data. The universal quasichemical (UNIQUAC) activity coefficient model was used to correlate the experimental data. Additionally, these water-alcohol-CPME systems were compared to watermethanol- chloroform system as a green alternative for Bligh and Dyer lipid extraction.
