Ultrastable superbase-derived protic ionic liquids.
Protic ionic liquids are synthesized via proton transfer from acids to organic bases. One of the key issues associated with conventional protic ionic liquids is the thermal instability resulting from temperature-induced decomposition via reverse proton transfer. This shortcoming significantly hampers the use of these protic ionic liquids in separations, electrochemical capacitors, fuel cells, a...
متن کاملSupported Liquid Membrane in Metal Ion Separation: An Overview
Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
متن کاملOn the formation of a protic ionic liquid in nature.
The practical utility of ionic liquids (ILs) makes the absence (heretofore) of reported examples from nature quite puzzling, given the facility with which nature produces many other types of exotic but utilitarian substances. In that vein, we report here the identification and characterization of a naturally occurring protic IL. It can be formed during confrontations between the ants S. invicta...
متن کاملSoluble, folded and active subtilisin in a protic ionic liquid.
The activity of proteases chymotrypsin and subtilisin dissolved in a range of protic hydroxylalkylammonium ionic liquids was tested against the model substrate APEE (N-acetyl-L-phenylalanine ethyl ester); activity was only observed for subtilisin in diethanolammonium chloride (DEA Cl), while chymotrypsin was not active in any PIL tested.
متن کاملLyotropic liquid crystal phases of phytantriol in a protic ionic liquid with fluorous anion.
The phase behaviour of phytantriol in the protic ionic liquid (PIL) 1-methylimidazolium pentadecafluorooctanoate (MImOF) and four different MImOF-water compositions was investigated by small- and wide-angle X-ray scattering (SAXS/WAXS), cross polarised optical microscopy (CPOM) and infrared spectroscopy (IR). MImOF is a distinct protic ionic liquid in that it contains a fluorocarbon anion and a...
