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.

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: The one-step coupling neutralization reaction (OCNR) method was proposed for the controllable synthesis of functionalized protic porous ionic liquids (PPILs). Three types of PPILs were synthesized based on tuning the position of the corona amino functional groups. The results showed that protic ion pairs and porous structure played crucial roles in the formation of PPILs and their extraction adsorption coupled desulfurization (EADS) performance.

Summary: The ZIF-8-PILs demonstrated high removal efficiencies for thiophene and benzothiophene under optimal conditions and can be easily recovered and reused due to their stable liquid porous structure. The synergistic effects of electrostatic interactions, hydrogen bonding, and pi-complexation interactions among ILs, ZIF-8, and sulfur compounds contributed to the high removal efficiency. The results suggest that PILs are a new and promising extractant for fuel extraction desulfurization process.

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: The conductor-like screening model was used to identify ILs for efficient extraction of PFOA, with [P6,6,6,14][Piv] found to be a suitable IL due to its strong chemical attraction for PFOA and beneficial physicochemical properties. Experimental results showed [P6,6,6,14][Piv] could remove >99.9% of PFOA in aqueous solution, but emulsification issues limited the removal rate to 80-91% at low PFOA/IL molar ratios. Washing the IL with 1% NaOH partially regenerated its ability to extract PFOA, allowing for reuse with a slightly decreased removal rate per cycle.

Summary: Polyvinyl butyral (PVB) waste, collected from end-of-life vehicles and post-consumer building laminated glass, is a valuable polymeric material that can be recycled. A lack of appropriate recycling techniques results in a significant amount of PVB waste being buried in landfills each year. This study focuses on purifying PVB from contamination by dissolving post-consumer polymeric materials in single and binary organic solvents. Experimental measurements and optimization of the dissolution time of PVB were conducted. The study found that PVB dissolves faster using a binary solvent (2-propanol + ethyl acetate) compared to pure 2-propanol. The obtained PVB solutions can be widely used as glues for various materials or transparent paint additives.
