[2,2'-Bipyridine]-1,1'-diium tricyanomethanide {[2,2'-BPyH][C(CN)3]2} as a bifunctional nanostructured ionic liquid catalyst (0.5 mol%) was used for the synthesis of 3,4-dihydropyrano[c]chromenes (14 examples) under solvent-free condition at room temperature in high yield (82-91%) and short reaction time. In addition, the described ionic liquid catalyst was also applied for the synthesis of bis...

1-butyl-3-methyl imidazolinium hydroxide ionic liquid (BMIm[OH]) is loaded on commercial low surface area Pd-Ag/α-Al2O3 solid ‎catalyst to enhance higher selectivity of acetylene partial hydrogenation. Different experimental techniques such as atomic absorption spectroscopy, surface area measurement and gas chromatography have been utilized to characterize chemical, structural and catalytic pro...

Vaporisation and liquid phase thermal decomposition, TD, of two halide ion ionic liquids, 1-octyl-3-methylimidazolium chloride, [C8C1Im]Cl, and 1-octyl-3-methylimidazolium iodide, [C8C1Im]I, are investigated using temperature programmed desorption (TPD) line of sight mass spectrometry (LOSMS) at ultra-high vacuum (UHV). The ability to use MS to distinguish between vaporisation and TD allows the...

An ionic liquid fabricated from an anionic cyclometalated platinum(ii) complex and an imidazolium cation exhibits dual emission from the monomeric and aggregated forms of the platinum complex anions, leading to temperature-dependent color changes of luminescence.

A new type of poly(ionic liquid) membrane, which shows switchable hydrated states via lower critical solution temperature-type phase behaviour, enables concentration of some water-soluble proteins from aqueous media.

The conversion of the cellulose into 5-HMF would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-HMF. Chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to cyclohydration of fructose to 5-HMF. In this paper, the sawdust has been directly degraded i...

H2O2 is produced at the interface between a room-temperature ionic liquid with decamethylferrocene as an electron donor and an acidic aqueous solution. The electron donor can be regenerated electrochemically.

The ionic liquid, N,N,N,N-tetramethylguanidiniumtriflate (TMGTf) was found to be an efficient catalyst solvent for Henry reaction between nitromethane and isatin derivatives to provide 3-hydroxy-3-(nitromethyl)indolin-2-one under mild conditions. The ionic liquid amenable to successive recycling without appreciable decrease in activity. Synthesized compounds have been screened for their anti-di...

This work is a new development of an extensive research program that is investigating for the first time shifts in the temperature of maximum density (TMD) of aqueous solutions caused by ionic liquid solutes. In the present case we have compared the shifts caused by three ionic liquid solutes with a common cation-1-ethyl-3-methylimidazolium coupled with acetate, ethylsulfate and tetracyanoborat...

Atomic force microscopy has been used to study the effect of temperature on normal forces and friction for the room temperature ionic liquid (IL) ethylammonium nitrate (EAN), confined between mica and a silica colloid probe at 25 °C, 50 °C, and 80 °C. Force curves revealed a strong fluid dynamic influence at room temperature, which was greatly reduced at elevated temperatures due to the reduced...
