Abstract: It is essential to replace the petroleum based feedstocks by renewable resources for the newlinesustainable development of industrial sector. Commercial production of carboxylic acids newlineis mainly carried out by chemical synthesis from petroleum feedstocks. However, newlinefermentation technology is also an attractive alternative to produce carboxylic acids from newlinerenewable sources. In order to make the fermentation route economically viable, it is newlinenecessary to develop novel fermentation processes that use highly efficient separation newlinetechniques. Among various available alternatives for recovery of carboxylic acids from newlinefermentation broth, reactive extraction with a chemical (acid and extractant reaction) newlinephenomenon is a promising technique. It can also be used for separation of acids from newlinevarious aqueous waste streams. Organophosphorus-based and long-chain aliphatic aminebased newlineextractants along with the diluents are effective for separation of carboxylic acids newlinefrom dilute aqueous solution. newlineThe existing literature suggests that great strides have been made in the separation newlineof lactic acid from aqueous solution using reactive extraction. The experimental study of newlinereactive extraction is limited to other carboxylic acids such as formic acid, acetic acid, newlinepropionic acid, butyric acid and nicotinic acid. Nicotinic acid and Butyric acid have huge newlinepotential as building-block chemicals in various pharmaceutical industries to produce newlinemany medicines. Propionic acid and acetic acid are widely used in food industry as a newlinepreservative. The study on the reactive extraction of propionic- and nicotinic acid using newlineextractant in a mixture of an inert diluent and a modifier is limited. The reactive newlineextraction study for recovery of propionic acid and nicotinic acid from fermentation broth newlineusing biocompatible mixture of diluents is also not reported in the literature. newlineIn the present study, the recovery of various carboxylic acids from aqueous newlinesolution using organophosphorus-based [tri-n-butylphosphate (TBP) and tri-noctylphosphine newlineoxide (TOPO) in the ran
