Herein, a series of imidazole derived task-specific deep eutectic solvents (DESs) based on protic ionic liquid were synthesized and used for CO2 capture. These DESs exhibited excellent absorption capacity up to 1.00 mol CO2/mol DES, the process could be adjusted by mole ratio hydrogen-bond acceptor donor. The effect temperature was also investigated. To deeply investigate mechanism these DESs, corresponding studied in situ IR analysis applied recording process. With help experimental...
Deep eutectic solvents (DESs) have emerged as promising substitutes for SO2 capture. In this work, an effective preorganization strategy was implemented to design DESs, aiming at improving the desorption property while ensuring absorption capacity in DESs. Several novel DESs with preorganized multi-imides hydrogen bond donors were synthesized and evaluated The results showed that studied exhibited high capacities. particular, ethylenurea (EU)/1-butyl-3-methylimidazolium chloride (BmimCl)...
Deep eutectic solvents (DESs) have been regarded as promising alternative absorbents for CO2 capture recently. In this work, a series of novel superbase/acylamido-based DESs with low viscosity were synthesized and used capture. 1,5-Diazabicyclo[4.3.0]non-5-ene (DBN)/2-imidazolidone (EU) (2:1) exhibited fairly high absorption capacity up to 23.02 wt % (1.75 mol per DES) at 45 °C 1 bar. Furthermore, the absorbent showed desorption efficiency excellent recycling performance during five...
Supported liquid membranes (SLMs) have exhibited great potential as interesting materials for the separation of olefin/paraffin mixtures. To further improve performance SLMs, novel and sustainable silver-based deep eutectic solvents (DESs) constructed from trifluoromethanesulfonate (AgCF3SO3) acetamide (CH3CONH2) were synthesized membrane liquids first time. Their formation mechanism structure investigated intensively, confirming that multiple coordination hydrogen-bonding interactions...
For the separation of an ethylene/ethane mixture, a novel copper(I)-based supported ionic liquid membrane (SILM) with high permeability has been fabricated. This SILM was prepared from polyvinylidene fluoride microporous impregnating copper(I) based IL which formed by cuprous chloride (CuCl) and 1-butyl-3-methylimidazolium ([Bmim][Cl]). Scanning electron microscopy, attenuated total reflection Fourier transform infrared spectroscopy, time flight mass spectroscopy were used to characterize...
In this work, a series of 1,3-dimethylthiourea (1,3-DMTU)-derived environmentally friendly deep eutectic solvents (DESs) were reported and used for nitric oxide (NO) capture. The DESs synthesized by mixing 1,3-DMTU with different hydrogen bond donors at molar ratios, their NO absorption performances investigated. All the possessed excellent performance. Notably, capacity 1,3-DMTU/P4444Cl (3:1, ratio) DES is 4.25 mol/mol. had paramount effect on performance DESs, these increased increase...
An integrated T-shaped oil/water separation system fabricated by copper meshes with opposite wettability was prepared in the study.
Abstract Oily wastewater, especially the emulsified one, causes serious environment pollution and poses threats to ecosystem resource recycling. Among various filtration media, porous polymeric membranes have gained tremendous attention in dealing with oily emulsions due their energy‐saving, cost‐effective, highly efficient features. However, alleviate membrane fouling by oil droplets ensure high separation efficiency, endowing superhydrophilicity underwater superoleophobicity via facile...
An analysis of the construction ion-containing CO2-based polycarbonates via metal-catalyzed immortal copolymerization propylene oxide (PO) and carbon dioxide in presence protic ionic liquids (ILs) as chain transfer agents is described. The reactions were catalyzed by binary (salen)CoO2CCF3/onium salt system absence added solvent. On basis results this study, which includes 1H NMR MALDI-TOF-MS data, it clear that role IL process dominated its anion. When anion liquid nucleophilic, such...
Deep eutectic solvents (DESs) have been extensively studied and applied to the absorption of acid gases. However, nitric oxide (NO) by DES has rarely reported. In this work, we found that NO can be absorbed azole-derived DESs effectively reversibly. A series with low viscosity based on tetrazolium (Tetz), triazole, imidazole as hydrogen bond donors (HBDs) common ionic liquids acceptors (HBAs) were prepared. The results showed tetrabutylphosphine chloride (P4444Cl) HBA or Tetz HBD exhibited...
Ionic liquid (IL) aqueous solutions (aq) have emerged as promising candidates for SO2 absorption. In this work, a new series of diamino polycarboxylate protic ionic liquids (DPPILs) aq with low viscosities and high stabilities were developed used capture. All the prepared absorbents could efficiently absorb low-concentration in simulated flue gas. Among them, DPPILs based on citric acid (CA) presented most excellent desorption performance; nearly all absorbed be easily desorbed under mild...
