Abstract: The growing demand for the production of propionic acid as it useful in chemical industry, pharmaceutical industry, preservations, drug delivery towards a more economical energy efficient technology. Reactive extraction is used over conventional method as conventional methods i.e., fermentation broth is expensive as well as unfriendly towards the environment. A specific extractant and various diluents are used in reactive extraction which gives us a promising technique for the acid extraction. Alamine 336 (TOA) was used with a combination of petroleum ether by varying concentrations. Physical and chemical extractions results are presented as equilibrium distribution, distribution co – efficient, extraction efficiency, loading ratio and volume percentage by varying concentrations. The propionic acid distribution between aqueous & organic phase reaches equilibrium over a concentration range of 0.04 kmol/m3 – 0.22 kmol/m3. The optimum TOA concentration is found to be 40% at which KD value for petroleum ether is 0.73. In petroleum ether the modified separation and loading ratio increases with decrease in TOA acid concentration in petroleum ether.
