Experimental and Theoretical Studies of Supercritical Fluid Behavior

A dynamic flow column apparatus is built and used to measure the solubilities of two decarboxylated amino acids, tryptamine and histamine, in supercritical ammonia (supercritical in pressure only) at 50(DEGREES)C. Solubilities are obtained for the pure solids and mixtures of the solids in 1:1 mole ratio. The solubilities of the mixed solids are determined using thin-layer chromatography. The feasibility of a partial isothermal separation of the two solids is investigated. The solubilities of the pure solids at three pressures, 1000, 2000 and 5000 psig and ideal solution theory as applied to mixtures of solids in a fluid suggest that a separation could be affected. However, the mixed solid solubility data indicate that no separation at 50(DEGREES)C is possible.
