Three kinds of acidic functional ionic liquid [HMIM]HSO₄, [HPy]HSO₄ and [Hnhp]HSO₄ were synthesized, and used in the desulfurization process of DBT in the model oil. The ionic liquids all performed excellent performance of desulfurization, in which [Hnhp]HSO₄ explained the highest desulfurization rate. The effects of conditions of the desulfurization process on the sulfur removal rate were studied catalyzed by ionic liquid [Hnhp]HSO₄. The results showed that the sulfur removal of DBT in model oil could reach 99.4% when n (H₂O₂)/n (S) = 8, t = 60 min, T = 60°C, V ([Hnhp]HSO₄):V (model oil) = 1:5. [Hnhp]HSO₄ could be recycled 6 times with merely a slight decrease in activity.

Tuning Proton Exchange and Transport in Protic Ionic Liquid Solution through Anion Chemistry was written by Huang, Gongyue;Porcarelli, Luca;Forsyth, Maria;Zhu, Haijin. And the article was included in Journal of Physical Chemistry Letters in 2021.SDS of cas: 478935-29-4 The following contents are mentioned in the article:

Herein, we demonstrate that the p.d. of proton reduction and hydrogen gas oxidation of protic ionic liquids is closely related to the proton exchange rate in the electrolyte. Through a careful design of anion chem., the proton exchange rate can be boosted by several orders of magnitude, reaching 200 kHz at 100°C. It is found that the enhanced proton exchange rate can effectively decrease the potential loss at the electrode, most likely through alleviating the H⁺ concentration gradient incurred by electrochem. reactions at the electrode surfaces. This research therefore highlights the strategy of using anions of medium-strength acids, such as H₂PO₄^–, for protic ionic liquids with enhanced proton exchange capability.

Enhancement of the selective enzymatic biotransformation of rutin to isoquercitrin using an ionic liquid as a co-solvent was written by Wang, Jun;Sun, Guo-Xia;Yu, Liang;Wu, Fu-An;Guo, Xi-Jie. And the article was included in Bioresource Technology in 2013.COA of Formula: C10H20N2O4S The following contents are mentioned in the article:

An ionic liquid (IL)-containing buffer system was first applied in the conversion of rutin to isoquercitrin. High substrate solubility was achieved to enhance the selectivity and efficiency of hesperidinase-catalyzed reaction. Ten ILs were selected as co-solvents to assist catalytic reactions in this biotransformation process. The transformed products of rutin were identified by LC-MS. The [Bmim][BF₄]-glycine-sodium hydroxide buffer (pH 9) (10:90, volume/volume) was found to be the best medium for the biotransformation of isoquercitrin from rutin with higher selectivity and efficiency. The reaction time was reduced by 0.33-fold while the conversion of rutin and the yield of isoquercitrin were increased by 1.67-fold and 2.33-fold.
