Reactive extraction is an efficient, economical and environmentally friendly method for separating acids from waste streams. The separation of organic residues from aqueous waste streams released from industries is essential from the point of view of pollution control and recovery of useful materials. Propionic acid has become an important feedstock in chemical industries for manufacturing biodegradable polymers and synthetic resins. The disposal of wastewater containing propionic acid has been recognized as a significant expense to the industry and the environment. This study used reactive extraction to separate propionic acid from an aqueous solution using Tri-n-Pentyl Amine and Tri-n-Butyl Amine with different diluents. Kinetic variables such as order of reaction, mass transfer coefficient and rate constants were determined by conducting kinetic studies using a stirred cell in a batch-type reactive system. Physical equilibrium experiments showed that 1-Octanol has the highest extractable strength compared to chloroform and dimethylene chloride. The distribution coefficient of chemical extraction is higher than that of physical extraction. Effect of acid (0.1 to 0.4 N), amine concentration (10% to 40%) is noticed in terms of Distribution coefficient KD in the range of 3 to 19 for TPA and KD in the range of 1.5 to 5.67 for TBA at 0.1N. The Equilibrium complexion constant (KE1) was calculated using the loading ratio (Z) at 10% to 40% amine in 1-octanol. At 40% maximum Equilibrium complexion constants for TPA KE1=10.28 and TBA KE1=5.94 were obtained. The reaction regime depended on the Hatta number value, with TPA being instantaneous and TBA being a fast reaction. The enhancement factors for TPA and TBA were found to be 5.1 and 3.8, respectively.
