“…23 An additional merit of quaternary amines are they could extract the acid under both acidic and basic conditions. 24 Some work, for instance Jung et al (1996), 25 Marinova et al ( 2004), 26 Uslu (2007), 27 and Inci et al (2011), 28 In the present work, equilibrium studies on L(+)-tartaric acid recovery using Aliquat 336 blended with n-heptane, kerosene, and 1-octanol was studied. To date, Aliquat 336 with n-heptane, kerosene, and 1-octanol was not chosen for the extraction of tartaric acid.…”

In the present study, extraction equilibria experiments for water + L(+)-tartaric acid + extractant/diluents were carried out at T = 300 ± 1 K for concentrations of L(+)-tartaric acid (0.1 to 1.0 mol·kg–1) and Aliquat 336 (0.22 to 0.88 mol·kg–1) in various diluents (n-heptane, kerosene, n-octanol). The equilibrium results were discussed in terms of the overall equilibrium complexation constant (K E(1:1)), loading ratio (z), extraction efficiency (E%), distribution coefficient (K D), dimerization coefficient (D), and partition coefficient (P). Kerosene + 0.88 (mol·kg–1) Aliquat 336 was found to be a favorable solvent with 50% extraction efficiency for the reactive extraction of L(+)-tartaric acid, whereas, 32.14% for n-heptane + 0.88 (mol·kg–1) Aliquat 336, and 22.22% for 1-octanol + 0.88 (mol·kg–1) Aliquat 336. 1:1 acid–amine complex was proposed for all the diluents with no overloading, that is, z < 0.5. A higher chemical extraction was observed in nonpolar diluents: n-heptane and kerosene. Further, equilibrium results were fitted with relative basicity and mass action law model and it was found that the relative basicity model predicted the results better than the mass action law for reactive extraction of L(+)-tartaric acid.

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.

“…Then, the formed reaction complexes are dissolved in the organic phase by means of solvents. Phosphorus-based tri- n -butyl phosphate or tri-octyl phosphine oxide, aliphatic amines of tri-n-octylamine, Alamine 336, Aliquat 336, tributyl phosphate, tributylamine, or Amberlite LA-2 − are commonly used as an extractant, which can chemically complex with the acid to form acid–extractant complexes. Amberlite LA-2 (a straight-chain secondary amine mixture) is a commercial product with molecular weight of 353.67 g·mol –1 and density of 0.83 g·mL –1 at 298.15 K. Table presents a brief literature review on the reactive extraction of various acids from aqueous solutions by using Amberlite LA-2.…”

Mandelic acid (MA) an α hydroxycarboxylic acid found in bitter almonds. It has gained importance in recent years, especially due to its use in the cosmetic industry. Separation processes of mandelic acid have a critical point in the production stages obtained the product form. In this study, extraction of mandelic acid from aqueous solutions was carried out using five different concentrations of Amberlite LA-2 (LA2) solution. Dimethyl phthalate (DMP), methyl isobutyl ketone (MIBK), 2-octanone, 1-octanol, n-pentane, octyl acetate, and toluene were used as diluents in the organic phase. The batch extraction results of mandelic acid were obtained for process design. The data were analyzed with respect to loading factor (Z), distribution coefficient (D), and extraction efficiency (E). In addition, the overall extraction constants, K 11, K 12, K 13, and K 23 have been determined for acid–amine complex. The maximum removal of mandelic acid in this study is 92.75% with MIBK and 0.57 mol·kg–1 initial concentration of Amberlite LA-2.
