Extraction of lactic acid by phosphonium ionic liquids

Ionic liquids in supported liquid membrane technology

“…As a result, the SLM impregnated with 1-Butyl-3-methylimidazolium hexafluorophosphate produced the highest selectivity for aromatic hydrocarbons, especially benzene [107]. Experiments with phosphonium ILs show promising results in extraction of organic acids, especially of lactic and butyric acids [108,109] with fairly higher distribution coefficients for solvents with ionic liquid compared to the classical solvents. Some hydrophobic ILs are surface active and has the tendency to form a relatively stable emulsion, what causes troubles with separation of phases.…”

Quaternary Ammonium and Phosphonium Ionic Liquids in Chemical and Environmental Engineering

“…The assumed extraction mechanism suggests the coordination of lactic acid (LA) to the IL under formation of complexes (LAH) p (IL)(H 2 O) 2 (with p ranging from 1-3). The uptake of LA by Cyphos ® IL 104 is directly connected with the water uptake of the IL, including the formation of reverse micelles in the IL and inclusion of water into hydrated complexes of lactic acid (Marták & Schlosser, 2007).…”

Ionic Liquids within Microfluidic Devices

“…Besides, ionic liquids offer the specificity required to separate similar compounds from each other (Wasserscheid & Eichmann, 2001). Several authors reported on the use of ionic liquids for extraction of biomolecules (Pei et al, 2009;Ge et al, 2010;Tomé et al, 2010), aromatic compound (Meindersma et al, 2005;Zhou et al, 2009), metals (Wei et al, 2003;Germani et al, 2007;Yoon et al, 2010;Egorov et al, 2010), and organic compounds (Marták & Schlosser, 2007;Simoni et al, 2010). The use of ionic liquids for enantioselective extraction was studied as well (Huh et al, 2006;Tang et al, 2010).…”
