“…This also, intriguingly, raises the possibility to form hydrophobic eutectic liquids with other acidic hydrogen-bond donors such as the carboxylic acids that have been targeted for extraction from fermentation broths [38][39][40][41]60 using TOPO and also for parallel formation for hydrophobic eutectic liquids. 22,23,[26][27][28] Liquid-liquid extraction studies…”

“…Trioctylphosphine oxide (TOPO) has many applications as a capping agent for the production of quantum confined nanomaterials. [32][33][34][35][36] and as an extractant 37 for metal ions and organic acids [38][39][40][41] and phenolic compounds. [42][43][44] However, an issue with TOPO is its relatively low solubility in hydrocarbon solvents that are the choice for aqueous-organic liquid-liquid extraction processes.…”

A low viscosity, hydrophobic eutectic solvent based on trioctylphosphine oxide (TOPO) has been developed and characterized, and its use as an extractant demonstrated for liquid−liquid separation of uranyl nitrate from aqueous acid. This strategy of liquefying the active extracting agent as a eutectic liquid produced liquids that contain an intrinsically high concentration of TOPO (ca. 80 wt %, 1.875 mol L −1 at χ TOPO = 0.50) and renders the use of an organic (hydrocarbon) diluent redundant.

“…Despite the great advance, this method probably will not be used in a real biorefinery facility, where all LA will be derivatized in aqueous solutions and without being isolated. Since LA is obtained from acid hydrolysis of biomass and its removal from the aqueous solution is technically difficult and a high‐cost process, methodologies that employs aqueous solutions of LA would be highly preferable. Another point is the catalytic system employed in these reactions.…”

The synthesis of several pyrrolidones (PYR), including a highly complex tetracyclic one (40‐91% yields), is described employing an inexpensive iron catalyst and aqueous solutions of biomass‐derived levulinic acid (LA) and formic acid (FA). The method is broad since it works with many structurally different amines. Considering that all produced LA from a real biorefinery facility will most probably be further derivatized directly from the hydrolysed biomass in aqueous solutions (without isolation), this method furnishes many advantages when compared to previous ones that employ different solvents or neat LA.

“…e removal of succinic acid using a hydrophobic organic phase consisting of tertiary amines dissolved in organic solvents has been under investigation by several researchers [7][8][9][10][11][12][13]. Recently, the extraction of carboxylic acids with ionic liquids and pressurized carbon dioxide is also gaining considerable importance due to nontoxicity and ease of operation [14][15][16][17][18][19][20][21][22][23][24][25].…”

The present study is aimed at using one of the most promising methods called reactive extraction to extract succinic acid from aqueous solution by using N,N-dioctyloctan-1-amine in biodiesel as diluent made from sunflower oil, rice bran oil, sesame oil, and karanji oil. The results of extraction studies with the diluents (physical) showed their inability to recover any acid by themselves. In reactive extraction, the organic phase extracting power solely depends on tri-n-octylamine. The ranges of the distribution coefficient are found as 7.62–18.12 for sunflower oil biodiesel, 8.33–17.45 for rice bran oil biodiesel, 7.0–17.67 for sesame oil biodiesel, and 9.85–21.36 for karanji oil biodiesel. The ranges of the loading ratio are 0.1–3.0 for sunflower oil biodiesel, 0.1–2.9 for rice bran oil biodiesel, 0.2–2.9 for sesame oil biodiesel, and 0.1–2.9 for karanji oil biodiesel. The karanji and sunflower oil showed higher values of distribution coefficient (KD) over rice bran oil and sesame oil which might be due to presence of both C20 and special fatty acids. The results show that biogenous diluents along with N,N-dioctyloctan-1-amine as extractant form a nontoxic and viable option for the extraction of succinic acid in the binary phase system.
