“…On the other hand, reactive extraction has been proposed as a promising approach for this purpose due to its high recovery, low energy requirement, process simplicity and thermal stability (6)(7)(8)(9)(10)(11)(12). Recently "green" chemicals such as ionic liquids (13)(14)(15)(16) and non-toxic diluents, e.g. vegetable oils (17)(18)(19)(20) have been used for organic phase formation.…”

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.

“…The functional heads such as ammonium, imidazolium, pyridinium, piperidinium, pyrolidinium etc. which contain quaternary nitrogen atom are considered to be the most common cations of ionic liquids (Chen et al, 2013;Seddon, 1996;Lagrost et al, 2003;Blahušiak et al, 2013;Mancini et al, 2013;Tong et al, 2013). However, the literature related to the application of ionic liquids in mineral flotation is scanty.…”

“…In this process, selection of appropriate solvent (extractant) is an important criterion to achieve high separation yield . In recent years, several researchers performed studies on the use of environmentally‐friendly organic phase materials such as natural diluents and ionic liquids; novel extractants were also reported . However, few studies on the reactive extraction of acrylic have been reported as summarized in Table .…”

BACKGROUND Acrylic acid has a wide range of applications in plastic additives, textiles, sealants, adhesives, and surface coatings industries. Owing to its widespread demand, production through a biotechnological method has emerged as low‐cost, energy‐efficient, environment friendly with few challenges at downstream stage. Reactive extraction is a promising method to recover carboxylic acid, but suffers from toxicity problems of the diluent and extractant employed. Therefore, there is a need for a nontoxic extractant and diluent or a combination of less toxic extractants in a nontoxic diluent that can recover acid efficiently. In this context, reactive extraction of acrylic acid from aqueous phase was employed with tri‐n‐butyl phosphate dissolved in natural diluents soybean oil, sunflower oil, and rice bran oil. RESULTS Reactive extraction results are discussed in terms of the partition coefficient (α), dimerization constant (β), distribution coefficient (KD), extraction efficiency (η%), overall equilibrium complexation constant (KE), and loading ratio (ϕs). Higher distribution coefficient and extraction efficiency range was found in tri‐n‐butyl phosphate (TBP) + sunflower oil as 0.672 to 2.019 and 39.76 to 66.49, respectively. Average extraction efficiency was in the range 30.85 to 71.94% for soybean oil, 39.76 to 66.49% for sunflower oil, and 31.27 to 69.42% for rice bran oil with 0.366 to 1.464 mol kg−1 of tri‐n‐butyl phosphate. CONCLUSION Sunflower oil with tri‐n‐butyl phosphate showed higher extraction efficiency for the reactive extraction of acrylic acid. The order of extraction efficiency was observed as: TBP+sunflower oil > TBP+soybean oil > TBP+rice bran oil. Since evasion of direct contact of the organism with the organic phase or use of nontoxic diluents can substantially reduce toxic effects, natural oils were used in the present study. Reactive extraction results can be employed for the design of extraction columns. © 2017 Society of Chemical Industry
