Extraction of organic compounds with room temperature ionic liquids

Study of Ether-, Alcohol-, or Cyano-Functionalized Ionic Liquids Using Inverse Gas Chromatography

“…[10][11][12][13][14][15][16][17][18][19][20] Nevertheless, there is a lack of data concerning the polar alkyl chain grafted on the cation such as ether-, alcohol-, or cyano-functionalized ILs. A systematic study of interaction between organic compounds and such ILs is needed to have a better understanding of the behavior of ILs in mixtures.…”

Interactions between Organic Compounds and Ionic Liquids. Selectivity and Capacity Characteristics of Ionic Liquids

“…The data for the 1-ethanol-3-methylimidazolium tetrafluoroborate, 1-ethanol-3-methylimidazolium hexafluorophosphate, 1,3-dimethylimidazolium dimethylphosphate and 1-ethyl-3-methylimidazolium diethylphosphate (Revelli et al, 2009a), 1-Butyl-3-methylimidazolium tetrafluoroborate (Revelli et al, 2009b), n-Acryloyloxypropyl-N-methylimidazolium bromide and n-Methacryloyloxyhexyl-N-methylimidazolium bromide (Mutelet et al, 2008), 1-Propenyl-3-alkyl-imidazolium bromide , 1-butyl-3-methylimidazolium octyl sulfate and 1-ethyl-3-methylimidazolium tosylate , Triethylsulphonium bis(trifluoromethylsulfonyl)imide (Domańska & Marciniak, 2009a), 1-Methyl-3-ethylimidazolium bis(trifluorosulfonyl)-amide and 1.2-Dimethyl-3-ethylimidazolium bis(trifluorosulfonyl)-amide (Krummen et al, 2002) were taken from the sources indicated. (Poole & Poole, 2010) found that the system constants of LSER model for the room temperature ionic liquids fall into the range e = −0.62 to 0.86, s = 1.7-2.8, a = 2.1-7.3, b = 0-1.07, and l = 0.35-0.96. Compared with the scale of the polar organic solvents e = −0.60 to 0.82, s = 0.54-2.8, a = 0.28-5.50, b = 0-4.8, and l = −0.21 to 0.98, we can see that both scales are similar indicating that the solvation properties for the room temperature ionic liquids are classical and fit quite well into the scales developed for polar molecular solvents.…”

Application of ionic liquid-based ultrasonic-assisted extraction followed by rapid resolution LC-ESI/MS to chromone analysis from radix saposhnikoviae

“…The extraction of four chromones from Radix Saposhnikoviae using UAE was performed by employing various extraction conditions, including solvents: water, ethanol, and [C 3 …”

“…ILs have a number of unique chemical and physical properties, such as negligible volatility and vapor pressure, good thermal stability, low flammability, chemical stability, environmental benignity, and good dissolution and extraction abilities [2][3][4][5]. The potential value of ionic liquid research has been recognized by chemists worldwide.…”
