“…(1) [2,19,33,34]. The carboxylic acid itself can also dissociate H + , which is able to act as a catalyst to accelerate the forming rate of -COOOH [19]. Therefore, both the carboxylic acid (-COOH) group in the cation and the ZnCl 3 -anion had catalytic functions in the oxidative desulfurization process for ZnCl 2 -based ILs.…”

“…The carboxylic acid (-COOH) group introduced into the cations of several acidic ILs was demonstrated to form peroxycarboxylic acid group with oxidative function by reaction with hydrogen peroxide under acidic catalyst [19,20]. Properties of ILs may be modulated by the selection of cation substituents and the associated anions for task-specific ILs.…”

Simultaneous desulfurization and denitrogen of liquid fuels using two functionalized group ionic liquids

et al. 2014

Deep desulfurization of liquid fuels is an important and challenging issue in worldwide petroleum refining industry. Extraction and catalytic oxidative desulfurization (ECODS) of liquid fuels using a series of ionic liquids (ILs) with two functionalized groups, such as [(CH 2 ) 2 COOHmim]Cl/nFeCl 3 , [(CH 2 ) 2 COOHmim]Cl/nZnCl 2 , and [Amim]Cl/nFeCl 3 , was studied. In the ECODS, the ILs were used as both extractant and catalyst and 30 wt% hydrogen peroxide (H 2 O 2 ) solution as oxidant. The effects of molar ratios of [(CH 2 ) 2 COOHmim]Cl (or [Amim]Cl) to FeCl 3 (or ZnCl 2 ) in ILs, H 2 O 2 /sulfur (O/S) molar ratio, reaction temperature, and the nature of sulfur compounds on sulfur removal were investigated. The natures of the functional groups (-COOH, -CH 2 -CH=CH 2 ) in cations and the acid strength of anions play important roles in the ECODS and affect the reaction time, temperature, and desulfurization efficiency of different substrates. Also, nitrogen-containing compounds (pyridine, pyrrole, and quinoline) could be removed simultaneously in the ECODS and had different effects on dibenzothiophene removal. ionic liquids, desulfurization, denitrogen, fuel

“…We should also mention the use of ILs containing either acidic anions ( [147,148] or COOH groups on their cations as extractants and catalysts in the oxidative desulfurization of dibenzothiophenes in the presence of H 2 O 2 in a model oil. N-Methylpyrrolidonium tetrafluoroborate has also been tested with success for the same application.…”

Acidic ionic liquids (ILs) are key systems in synthesis and their performances depend greatly on their cation and anion structure and their liquid-state organization. This microreview reports several examples of Bronsted and/or Lewis acidic ILs that have been selected to highlight the main peculiarities of these systems potentially fundamental for rational design and development of new ionic media and catalysts. Fundamental physico-chemical properties, optimization of which through tailoring of molecular structures could favor more efficient and sustainable applications, are discussed
