Separation of Low-Volatile Substances Using Compressed Gases
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 . The present investigations were concerned with the oleic acid/stearic acid system , 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.
