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.

Catalytic membrane contact reactors (CMCRs) were evaluated for the selective three-phase hydrogenation of the model reaction, the partial hydrogenation of soybean oil (PHSO). PHSO produces copious amounts of trans-fats when carried out in a batch slurry reactor due to hydrogen starvation at the catalyst, caused by inherent mass transfer limitations of the system. In this study composite ceramic/polymer membranes were rendered catalytically active by depositing a polymer-palladium complex, (poly(N-vinyl-2-pryyolidone) (PVP)-palladium (Pd)), onto the selective skin of the membrane. Hydrogen gas was supplied to the support side of the membrane, the hydrogen gas permeated from the support side to the skin side of the membrane, where it dissociated onto the catalyst surface. Liquid reactant was circulated over the skin side of the membrane, allowing the three components to come into contact and react. Our system is shown to be nearly zero order in hydrogen, indicating that the catalyst surface maintains high hydrogen coverage throughout. CMCRs produced 50% less trans-fat at equivalent levels of hydrogenation compared to slurry reactors. It was further demonstrated that an increase in
