“…The reactive extraction is found to be a promising method for the recovery of the carboxylic acids from a dilute fermentation broth [5][6][7][8][9][10]. This separation method has advantages such as the following: Kertes and King [3] categorize the extractants as three major types:…”

The prospective function of a novel energy efficient fermentation technology has been getting great attention in the past fifty years due to the quick raise in petroleum costs. Fermentation chemicals are still limited in the modern market in huge part because of trouble in recovery of carboxylic acids. Therefore, it is needed considerable development in the current recovery technology. Carboxylic acids have been used as the majority of fermentation chemicals. This paper presents a state-of-the-art review on the reactive extraction of carboxylic acids from fermentation broths. This paper principally focuses on reactive extraction that is found to be a capable option to the proper recovery methods.

“…The economics of the process, however, depends on the development of an effective recovery method for the organic acids from the broth [2]. Solvent extraction processes as a promising recovery technique have been proposed as an alternative to the conventional precipitation process [3], and many solvents have been tried to improve such recovery [4][5][6][7][8]. The extraction technique has the advantage of continuously removing the acid from the fermented broth and keeping the acids concentration in the broth to a low level.…”

The liquid-liquid equilibrium for the quaternary system of o-xylene(1)+water(2)+butyric acid(3)+ethyl acetate(4) was measured at 25 o C and atmospheric pressure. Binodal curves, tie-lines, distribution, and selectivity for the quaternary system have been determined in order to investigate the effect of binary solvents, o-xylene and ethyl acetate, on extracting butyric acid from aqueous solution. In addition, these experimental tie line data were also compared with the values predicted by the UNIFAC model. It is found that UNIFAC group interaction parameters used for LLE could not provide a good prediction.

“…Owing to a suitable extraction system, it is possible to achieve a good selectivity, and high concentration. In addition, extraction does not affect the thermal stability of the reactants, does not require additional energy consumption and retains pollution, and other by-products in the broth 6 . Furthermore, in the case of extraction it is easy to control the pH in the fermentor by continuous removal of the acid, the possibility of recycling the solvent, thus, reducing the amount of waste and reducing the production costs 1 .…”

This paper presents investigation on removal of low molecular organic acids (acetic, lactic, succinic and fumaric) from aqueous solutions with reactive extraction. The results specifi cally show that the extraction effi ciency of acids depends on the type of extractant, diluents of the organic phase and the initial pH of the aqueous phase. It is possible to separate succinic or fumaric from lactic and acetic acids with high selectivity with the use of TOA and Aliquat 336, respectively. Increasing the pH of the aqueous phase results in a reduction of fumaric acid extraction effi ciency with solvating extractants. This can be explained by the decreasing share of acidic form, whose extraction is favored by these extractants. Effi cient extraction of both fumaric acid and fumarate using Aliquat 336 can be explained by the ionic structure of the quaternary ammonium salt, capable of transporting both forms of the acid.
