Separation and reaction processes are key components employed in the modern chemical industry, former accounts for majority of energy consumption therein. In particular, hydrocarbon separation purification processes, such as aromatics extraction, desulfurization, denitrification, challenging petroleum refinement, an industrial cornerstone that provides raw materials products used human activities. The major technical shortcomings solvent extraction volatile loss, product entrainment leading to secondary pollution, low efficiency, high regeneration due use traditional organic solvents with boiling points agents. Ionic liquids (ILs), a class designable functional or materials, have been widely replace conventional after nearly 30 years rapid development. Herein, we provide systematic comprehensive review state-of-the-art progress ILs field extractive (i.e., denitrification) including (i) molecular thermodynamic models IL systems enable large-scale screening candidates phase equilibrium prediction processes; (ii) structure-property relationships between anionic cationic structures their performance selectivity distribution coefficients); (iii) IL-related mechanisms (e.g., magnitude, strength, sites intermolecular interactions depending on system structure); (iv) process simulation design at scale based validated models. short, this Review easy-to-read exhaustive reference mixtures from multiscale perspective molecules, thermodynamics, processes. It also extends analogs, deep eutectic (DESs) research area, discusses current challenges faced by related fields well future directions opportunities.

Abstract A novel synergistic extractant consisting of a deep eutectic solvent (DES) and tri‐n‐butyl phosphate (TBP) is proposed for selective extraction valuable metals from waste lithium‐ion batteries (LIBs). The efficiencies Ni 2+ , Co Mn were 99.8%, 99.1%, 95.9%, respectively, high‐purity Li + was enriched in the raffinate after single‐stage extraction. Valuable metal salts, lithium carbonate (92.3 wt%) cobalt oxalate (94.9 wt%), obtained. DES TBP retained its high performance even multiple regeneration cycles. process followed so‐called “cation exchange mechanism” with thermodynamic properties Δ H < 0, G S 0. molecular‐level mechanism demonstrated that dominated by both electrostatic coordination interactions between ions DES/TBP, based on quantum chemical calculations. This study aims to provide new strategy recycling LIBs.

In this work, low-transition temperature mixtures (LTTMs) are used for the first time in separation of isobutanol (IBA) and isobutyl acetate (IBAC) by extraction, relationship between weak interactions phase equilibrium behavior is systematically investigated. LTTMs screened using conductor-like screening model segment activity coefficient (COSMO-SAC), with ethylene glycol as hydrogen bond donor (HBD) benzyltrimethylammonium chloride, choline tetramethylammonium chloride acceptor (HBA). The effectiveness further demonstrated through liquid–liquid (LLE) experiments, NRTL chosen to correlate experimental data process design. Finally, quantum chemical calculations provide insights into effect structure on LLE IBA/IBAC system, results show that extraction properties mainly dependent type HBAs increase enhanced electron-donating ability moiety.
