“…Imidazolium tetrafluoroborate ILs are stable up to 300 °C. Some imidazolium tetrafluoroborates with an allylic side chain showed wider voltage windows on the platinum electrode, better conductivities, and lower viscosities as compared to the corresponding ILs containing the saturated side chains [63].…”

“…Graphene nanoplatelets purchased from Xiamen Knano Graphene Technology Co. Ltd. Sunset yellow, tartrazine, and other reagents were of analytical grade from Aldrich. 1-Allyl-3-methylimidazolium tetraflouroborate ([AMIM] [BF 4 ]) as room temperature ionic liquid was home-made, synthesized according to literature by some alteration [18]. Briefly, to a stirred solution of N-methyl imidazole (4.105 g, 50.0 mmol) in acetonitrile (40 ml) was added requisite 3-bromo-1-propene (6.654 g, 55 mmol) drop-wise at 0°C.…”

Carbon-ceramic electrode modified with 1-allyl-3-methyl imidazolium tetraflouroborate ionic liquid was constructed. Scanning electron microscopy, X-ray diffraction analysis), energy dispersive X-ray analysis proved that the deposition of ionic liquid on the surface of carbon-ceramic electrode caused formation of graphene nanoplatelet-like structures on its surface. This electrode was used for simultaneous electrochemical determination of sunset yellow (SY) and tartrazine (Tz). Operational parameters such as pH of solution and ionic liquid volume which affected the analytical performance of modified electrode were optimized. The present electrode exhibited linear response to SY and Tz in concentration range of 1×10 −7 -1.5×10 −5 M and 1×10 −7 -2×10 −5 M with a detection limit of 7.3×10 − 8 M and 8.1×10 −8 M, respectively. The high repeatability, reproducibility, long-term life time, and low response time (<3 s) are advantages of modified electrode. The modified electrode was successfully applied for simultaneous determination of SY and Tz in different food samples, and the results were in good agreement with those obtained from HPLC method.

“…The most common ionic liquids used in the organic reactions are imidazole and pyridinium-based cations with organic or inorganic anions. So two different series of ionic liquids, based on methyl imidazole and pyridinium cations, were synthesized and purified in the laboratory through standard procedures [20,21]. Medium to longchain alkyl halides (butyl to decyl) were used for the synthesis of ionic liquids via quaternization of methyl imidazole or pyridine.…”

1-Substituted 1,2,4-triazole derivatives present in a large number of compounds and display a variety of bioactivities such as antibiotic, anti-inflammatory, antidiabetic, antipsychotic, and anticancer. A regioselective protocol has been developed for the alkylation of 1,2,4-triazole using mild conditions. The 1-alkyl-1,2,4-triazole derivatives were synthesized under microwave conditions using potassium carbonate as a base and ionic liquid (hexylpyridinium bromide) as a solvent. The products were obtained in excellent yield, and the base-ionic liquid combination was recycled for a number of times.
