“…Secondly, the extraction solvent should be chosen such that it has a high partition coefficient of the carboxylic acid, meaning it has a high preference for the organic phase over the aqueous phase, and a high selectivity for extraction of carboxylic acid over water, in order to limit the co-extraction of water. And thirdly, the extraction system should be reversible, so the solvent should be well recoverable [52,53].…”

“…vegetable oils (17)(18)(19)(20) have been used for organic phase formation. Moreover, novel extractants have recently been used instead of conventional extraction agents (21)(22)(23)(24). It has been shown that reactive extraction is applicable for separating carboxylic acids of similar structures from their mixed solutions (25).…”

Combined use of inert diluents with polar modifiers enables former to be utilized for the recovery of polar value-added chemicals. The results show that polarities of both solvent and modifier are critical for efficient separations. Thus, K D values with 1-octanol were higher than those with 1-decanol; while those with xylene were superior to those with hexane and toluene.Increasing amine concentrations increased the K D values, in contrast to the trends with pH and temperature. About 33%, 79% and 67% of acetic acid was recovered using 25% (v/v) Alamine 336 in xylene, 1-octanol and 30% 1-octanol-modified xylene, respectively.A c c e p t e d M a n u s c r i p t 2 Therefore, solvent modification positively affects the extraction power of inert diluents for acetic acid recovery.

“…CED is a versatile technology that can concentrate, dilute, and separate matter whilst producing relatively Acetic acid, one of the VFAs that can be extracted, also has uses beyond conversion to an energy carrier. It has been called "one of the world's most important chemicals" (Ijmker et al, 2014) due to widespread use in manufacturing polymers, polyethylene terephthalate, and solvents. According to market forecasts, its global demand in 2013 was 10.4 mt, and by 2020 its market revenue is expected to reach $12.2 billion.…”
