Density and dynamic viscosity data of binary mixtures of ionic liquids (ILs) were determined in this work, at temperatures from 283.15 to 363.15 K and at 0.1 MPa. The mixtures of two ILs comprise a common cation and different anions, combining 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide with eight other ionic liquids, namely, 1-butyl-3-methylimidazolium thiocyanate, 1-butyl-3m...

Decomposition of transition-metal amidinates [M{MeC(NiPr)2} n ] [M(AMD) n ; M=MnII, FeII, CoII, NiII, n=2; CuI, n=1) induced by microwave heating in the ionic liquids (ILs) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]), 1-butyl-3-methylimidazolium trifluoromethanesulfonate (triflate) ([BMIm][TfO]), and 1-butyl-3-methyl...

A green and efficient ionic liquid-based ultrasound-assisted in-situ solvent formationmicroextraction (IL-UA-ISFME) in combination with high-performance liquid chromatographyultravioletdetection (HPLC-UV) has been successfully developed for the trace determination offive selected polycyclic aromatic hydrocarbons (PAHs) in environmental water samples. In thismethod, a hydrophobic ionic liquid (1...

A sensitive determination method was developed for the analysis of pyrethroid pesticide residues in tomato samples using ionic liquid-based dispersive liquid-liquid microextraction. A hydrophobic ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate) and acetonitrile were used as the extraction solvent and dispersive solvent, respectively. The following experimental parameters affecting...

In this research, the treatment of cyclohexanone, malononitrile, and aromatic aldehydes was carried out for successful synthesis orthoaminocarbonitrile tetrahydronaphthalenes by using butyl-3-methylimidazolium hexafluorophosphate as a base catalyst. protocol, target products were obtained in high to excellent yields between 85% 95% short reaction times 10 20 min under mild conditions. All ident...

Microporous polymers based on anionic macroinitiator and toluene 2,4-diisocyanate were used as a support for 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF₆]) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf₂N]) immobilization. The polymeric support was modified by using silica particles associated in oligomeric media, and the influence of the modifier us...

The direct electrochemical reduction of hemin, protoporphyrin(IX) iron(III) chloride, ligated with strong or weak heterocyclic bases, was investigated in the ionic liquids (IL), 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) and 1-octyl-3methylimidazolium hexafluorophosphate ([omim][PF6]), using cyclic voltammetry and chronocoulometry. Hemin complexed with N-methylimidazole (NMI)...

Fluorescence emission of the cationic form of fluorescein is observed from dilute aqueous acidic solutions in the presence of ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate which is otherwise observed only from aqueous solutions of very high acidity.

Ultrafast solvent dynamics of room-temperature ionic liquids have been investigated by optical heterodyne-detected Raman-induced Kerr-effect spectroscopy ~OHD-RIKES! by studying the effects of cation and anion substitution on the low frequency librational modes. The spectra of two series of imidazolium salts are presented. The first series is based on the 1-butyl-3-methylimidazolium salts @bmim...
