Interactions between ionic liquids and radicals

Molecular Volume Effects on the Dynamics of Polymerized Ionic Liquids and their Monomers

“…A series of 1-alkyl-3-methylimidazolium room temperature ionic liquids has been studied to determine how density, viscosity, melting point, ionic conductivity and thermal stability are affected by changes in alkyl chain lengths of the cation and the nature of the anion [47][48][49][50][51]. Fig.…”

Volumetric properties of 1-butyl-3-methylimidazolium bromide in aqueous solutions of d(−)-ribose and d(−)-arabinose at different temperatures

“…ILs have attracted considerable interest due to their unique physicochemical properties, and these properties can be fine tuned by suitable combination of cations and anions [4][5][6]. ILs have been extensively used for various applications such as biomass dissolution, electrolytes in batteries, solar cell, reaction media, electrodeposition, purification, extraction and bioseparation processes [7][8][9][10][11][12].…”

Synthesis of traditional and ionic polymethacrylates by anion catalyzed group transfer polymerization

“…Therefore, the higher temperature used in the experiments discussed in this work may cause the higher polydispersity of the PMMA sample under our experimental conditions (Table ). The elevated temperature was selected in this work to reduce the viscosity of the ionic liquid from 75 mPa s at 23 °C to 15 mPa s at 70 °C . Nevertheless, viscosity of the ionic liquid was significantly higher compared with molecular solvents such as tetrahydrofurane (0.46 mPa s at 25 °C) and acetonitrile (0.34 mPa s at 30 °C) .…”

“…Moreover, viscosity of the ionic liquid methacrylates increases from methyl to butyl substituted ILMA although hexyl substituted ILMA does not show a further viscosity increase (Table ). Viscosity data summarized in Table show that viscosity of ILMAs is between 8 to 15 times higher compared with 1‐butyl‐1‐methylpyrrolidinium bis (trifluoromethylsulfonyl)imide at 23 °C …”

“…Solvents investigated in GTP range from toluene, methylene chloride, ethylene dichloride, tetrahydrofurane, and acetonitrile up to a hydrophobic ionic liquid. The latter belongs to interesting new solvents that have a negligible vapor pressure on the one hand, and a higher viscosity compared with traditional organic solvents on the other hand . Particular, the hydrophobic ionic liquid possesses a high application potential even if its water content is higher compared with organic solvents …”
