Abstract

The solubility of components in compressed gases can be used to separate substances with low vapor pressures. Several authors have suggested making use of this effect [1]. The present investigations were concerned with the oleic acid/stearic acid system [2], with the glycerides of oleic acid [3,4] and with mixtures of fatty acids of different degrees of Saturation. For example, the Separation of monoglyceride from a mixture of glycerides of the oleic acid demonstrated that a Separation process using compressed gases is possible without expanding and recompressing the circulating gas. In these investigations we used a semi-commercial apparatus with plate columns.
