Summary: In this article, a series of effective catalysts based on betaine and sulfuric or phosphomolybdic acids were obtained. These compositions were characterized and tested in the oxidation of sulfur- and nitrogenous-containing compounds by H2O2. The acidity change is non-linearly influenced by the amount of heteropolyacid (HPA), and the removal of sulfur-containing compounds is correlated with the concentration of Bronsted acid sites on the catalyst surface. On the other hand, the removal of pyridine is primarily determined by the content of heteropolyacids in the catalyst.

Summary: It is important to develop sustainable denitrogenation technology due to the impact of nitrogen compounds on the quality of fuel oils. To address the issues of incomplete denitrogenation and harsh conditions, an extractive denitrogenation method using eco-friendly piperazine-based ionic liquids (Pi-based ILs) was developed. The study evaluated the performance of the synthesized Pi-based ILs in removing pyrrole from oil and investigated the conformational relationship between denitrogenation performance and ILs structure. The results showed that the eco-friendly [C1Pi][Lac] exhibited the highest removal efficiency of 95.90% under optimal denitrogenation conditions.

Summary: The distribution of pyridine between the IL-rich phase and hydrocarbon-rich phase was predicted using the QSPR approach. A large dataset of 51 ternary systems was collected, which covered 19 cations, 14 anions, and 10 hydrocarbons. Linear and non-linear models were developed using MLR and MLP, respectively, with acceptable prediction capability. The study also investigated the impact of structural changes in cations, anions, and hydrocarbons on pyridine distribution.

Summary: This study analyzed the performance of three imidazolium-based ionic liquids in reducing the interfacial tension between crude oil and IL solutions under a wide range of salinities. It was found that longer alkyl chain ILs accumulated more at the solution interface under high ionic strength conditions, leading to a greater reduction in IFT. Additionally, under low salinity conditions, longer alkyl chain IL exhibited a lower IFT value in diluted seawater compared to diluted formation water.

Summary: This study investigates the release characteristics of two components of ionic liquids (ILs) in transdermal preparations and their underlying mechanism. The results show that the release amounts of the two components in different pressure sensitive adhesives (PSAs) are significantly different, indicating a lack of synchronous release. The interactions between PSAs and drugs are mainly through dipole-dipole interactions, hydrogen bonds, ionic bonds, and ionic hydrogen bonds. This study provides scientific guidance for the application of ILs in transdermal preparations.

Summary: By introducing porous boron nitride into ionic liquids, the efficiency of sulfur extraction from fuel oil can be improved. Using m-BN-PIL as an extractant under optimized conditions achieves desulfurization performances of 59.2% and 61.8% for dibenzothiophene and 4-methyldibenzothiophene, respectively. After four stepwise extractions, the extraction efficiency over dibenzothiophene reaches 98.2%, achieving deep desulfurization of fuel oil.

Summary: Various ionic liquids were synthesized and the benzothiazole bisulfate was found to be the most effective extractant for removing pyridine, aniline, and quinoline. Single-stage and two-step extractions were conducted on simulated oil to compare denitrogenation performance. The extraction process was further described by kinetic equations, with IL recovery achieved through back-extraction and liquid-liquid separation.

Summary: This study selected an appropriate ionic liquid to separate ethyl acetate and ethanol, and investigated the interaction mechanism between solvent molecules and the ionic liquid through quantum mechanics calculations and molecular dynamics simulations. The results showed that the introduction of ILs has a prominent effect on reducing the number of hydrogen bonds among solvent molecules. Increasing the concentration of the cation will enhance the interaction with solvent molecules.

Summary: The chemical industry needs environmentally friendly processes, as acid-catalysed processes may cause environmental problems. The search for sustainable alternatives to conventional acids is urgent. Metal-containing ionic liquids have been of great interest to scientists due to their high Lewis acidity, which depends on the composition of the ionic liquid and the specific content of metal salt. These compounds are widely used as catalysts, co-catalysts, or reaction media in various fields of chemistry, particularly in organic chemistry. Gallium(III)- and indium(III)-containing ionic liquids effectively enhance the activity of metal salts and are easier to handle. This review emphasizes the wide range of applications and the potential of metal-containing ionic liquids, with a focus on Ga(III) and In(III), which can guide further research and synthesis of new compounds in this group.

Summary: This study used MD to investigate desulfurization of a diesel oil model using MILs. The results showed that [bmim][FeCl4] had the highest DBT affinity and its S-removal efficiency increased with temperature and MIL concentration. Research on the alkyl chain length of the MIL cation, temperature, initial sulfur content, and mass ratio showed that MIL exhibited good extraction performance for diesel oil models with different sulfur contents.

Summary: This study developed a new methodology for screening suitable cation and anion molecules to achieve maximum sulfur removal efficiency. The best structural descriptors were selected using Genetic Algorithm, and then the most proper cations and anions were chosen using Principal Component Analysis (PCA). It was concluded that ionic liquids with imidazolium and pyridinium cations with hexyl chain, combined with [N(CN)2] and [Ac] anions, are promising extraction solvents for desulfurization.

Summary: Extractive desulfurization using ionic liquids has attracted attention due to its simplicity and easy operating conditions. However, the selection of suitable cations and anions remains a challenge. This study developed a methodology to screen cation and anion molecules for maximum sulfur removal efficiency. Through genetic algorithm and principal component analysis, it was determined that certain imidazolium and pyridinium cations combined with specific anions are promising for extractive desulfurization. The selected ionic liquid, [HMPY][N(CN)2], was synthesized and evaluated, showing potential as a solvent for removing DBT or BT from n-heptane.
