Liquid–Liquid Equilibria for Ternary Systems of Water + Methoxycyclopentane + Alcohol (Methanol, Ethanol, 1-Propanol, or 2-Propanol)
2016
Liquid–liquid equilibria 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 activity coefficient model was used to correlate the experimental data. Additionally, these water–alcohol–CPME systems were compared to the water–methanol–chloroform system as a green alternative for Bligh and Dyer lipid extraction.
