Abstract A new strategy for multi‐molar absorption of CO 2 is reported based on activating a carboxylate group in amino acid ionic liquids. It was illustrated that introducing an electron‐withdrawing site to anions could reduce the negative inductive effect while simultaneously interact with very efficiently. An extremely high capacity (up 1.69 mol −1 ) aminopolycarboxylate‐based liquids thus achieved. The evidence spectroscopic investigations and quantum‐chemical calculations confirmed...
Amino acid ionic liquids (AAILs) are chemical solvents with high reactivity to CO 2 . However, they suffer from drastic increase in viscosity on the reaction , which significantly limits their application industrial capture of In this work, 1‐ethyl‐3‐methylimidazolium acetate ([emim][Ac]) also exhibits affinity but low viscosity, and its does not drastically after absorption, was proposed as diluent for AAILs fabricate hybrid materials. The AAIL+[emim][Ac] hybrids were found display enhanced...
Nowadays the knowledge of thermodynamic properties for amino acid ionic liquids (AAILs) has been paramount design many chemical processes. In this present work, a series cholinium-based AAILs ([Ch][AA]) were synthesized by neutralization choline hydroxide solution with five acids and then characterized 1H NMR, Fourier transform infrared (FT-IR), elemental analysis, thermogravimetry, differential scanning calorimetry (DSC) analysis. Physico-chemical such as density, viscosity, refractive...
Electronic properties of boron nitride nanosheets were tamed by doping carbon atoms into the matrix for boosted aerobic catalytic performance.
In this work, a class of deep eutectic solvents (DESs) formulated by choline chloride (ChCl), phenol (PhOH), and ethylene glycol (EG) were designed synthesized for NH3 capture. The effects temperature, pressure, DES composition on capacities investigated systematically. By utilizing the weak acidity PhOH, highly efficient reversible absorption was realized in PhOH-based ternary DESs. prepared DESs can reach as high 9.619 mol/kg (0.162 g/g) at 298.2 K 101.3 kPa, ranking one best reported to...
Abstract A novel method for the highly efficient and reversible capture of CO in carbanion‐functionalized ionic liquids (ILs) by a C‐site interaction is reported. Because its supernucleophilicity, carbanion ILs could absorb efficiently. As result, relatively high absorption capacity (up to 0.046 mol −1 ) was achieved under ambient conditions, compared with solubility commonly used IL [Bmim][Tf 2 N] (2×10 −3 ). The results quantum mechanical calculations spectroscopic investigation confirmed...
Novel superacid SO4H-functionalized ionic liquids (SFILs) were designed and prepared in this work. The catalytic activities of SFILs evaluated xylan hydrolysis xylose dehydration to produce furfural. Combined with the results acid strength characterized by solid-state 31P MAS NMR, it was found that performance positively correlated their strength. SFIL [Ch-SO4H][CF3SO3] displayed best more than 80% yield furfural, also obviously superior usual SO3H-functionalized acidic ILs, mineral liquid...
Alkali lignin, a significant waste resource from the pulp and paper industry, is produced in large quantities each year, but its utilization remains limited. This study focuses on cleavage of –OCH3 groups attached to aromatic ring alkali lignin obtain demethylated nanospheres (DAL-NPs) enriched with hydroxyl (Ar–OH) groups. These DAL-NPs are intended for efficient adsorption NH3. Qualitative quantitative characterization both pre- post-demethylation, was performed using Fourier transform...
Abstract Achieving efficient dissolution of carbon monoxide (CO) in the solvent is very helpful for implementation carbonylation reaction at ambient pressure. However, almost all common solvents show low solubilities CO high temperature. Herein, a series cuprous‐based ternary deep eutectic (DES) was prepared by mixing imidazolium hydrochloride with CuCl and ZnCl 2 . The DES [BimH]Cl‐CuCl‐1.0ZnCl exhibited large absorption capacity (0.075 mol −1 , 1 bar) even temperature (353.2 K), which...
