Solubility of o-and p-Aminobenzoic Acid in Ethanol + Carbon Dioxide at 308.15 K to 318.15 K and 15 bar to 85 bar

摘要

The solubility of o-and p-aminobenzoic acid in ethanol + carbon dioxide (CO_2) was determined at 308.15 K and 318.15 K in the pressure rawnge from 15 bar to 85 bar. The mole fraction of CO_2 in the liquid phase increses with pressure and decreases with temperature. The solibility of the solites decreases with pressure and increases with temperature.
