Abstract

Bharath, R., Inomata, H., Adschiri, T. and Arai, K., 1992. Phase equilibrium study for the separation and fractionation of fatty oil components using supercritical carbon dioxide. Fluid Phase Equilibria, 81: 307-320. Vapor-liquid equilibria were measured for the binary systems oleic acid-carbon dioxide and triolein-carbon dioxide and for the ternary system oleic acid-triolein-carbon dioxide with the aim of separating the fatty acids and triglycerides. Experimental results showed that oleic acid can be selectively extracted using supercritical carbon dioxide as a solvent. Supercritical carbon dioxide was also considered for the fractionation of mixtures of triglycerides. High pressure vapor-liquid equilibria were measured for the systems palm kernel oil-carbon dioxide and sesame oil-carbon dioxide. Supercritical carbon dioxide was found to fractionate these triglyceride mixtures on the basis of the total carbon number of the constituent fatty acids of the triglyceride.
