Ionic Liquids in Separation Techniques

Effects of pre-treatment technologies on dark fermentative biohydrogen production: A review

“…The common types of ILs that exist are imidazolium, tetra alkylphosphonium, pyridinium, pyrrolidinium and quaternary ammonium (Flieger et al, 2014;Torralba-Calleja et al, 2013;Vancov et al, 2012;Han and Row, 2010). Considered as green solvents, ILs are now being employed for lignocellulosic biomass pre-treatment (Gunny and Arbain, 2013;Yang and Wyman, 2008;Kim et al, 2011;MoraPale et al, 2011;Lee et al, 2014).…”

“…ILs are organic salts, consisting of organic cations and inorganic anions that behave as liquids at temperatures <100 C Vancov et al, 2012;Flieger et al, 2014). The common types of ILs that exist are imidazolium, tetra alkylphosphonium, pyridinium, pyrrolidinium and quaternary ammonium (Flieger et al, 2014;Torralba-Calleja et al, 2013;Vancov et al, 2012;Han and Row, 2010).…”

Influence of the alkyl group on thermophysical properties of carboxylic acids in 1-butyl-3-methylimidazolium thiocyanate ionic liquid at various temperatures

“…The excess molar volumes, V E m ; for the systems studied systems were calculated using equation (1) from the values of density of the mixture and the pure components: Ionic liquids are complex solvents, and have a capability to interact with acetic or propionic acid molecules simultaneously through, dispersive, ionic, hydrogen bonding, and dipolar interaction [36]. The negative V E m values for the binary system suggest that a more efficient packing and/or attractive interaction occurred when the [BMIM] + [SCN] À and acetic or propionic acid were mixed [36].…”

“…Ionic liquids (ILs) are a group of organic salts which contain organic cations and inorganic anions [1]. In many cases, they are defined as solvents that are liquid at ambient temperature and consist entirely of ions [2].…”

Comparison of mouse plasma and brain tissue homogenate sample pretreatment methods prior to high-performance liquid chromatography for a new 1,2,4-triazole derivative with anticonvulsant activity

“…The SPE sorbents are based mainly on modification of silica [10,11], copolymers of styrene and divinylbenzene [12][13][14][15][16]. Mixed-mode sorbents with either ion-exchange or alkyl groups are also available.…”
