Specification of Zwitterionic or Non-Zwitterionic Structures of Amphoteric Compounds by Using Ionic Liquids

Acta Chimica Slovenica, 2020
Some imidazolium-based ionic liquids were used to determine zwitterionic or non-zwitterionic structures of glycine and p-amino benzoic acid, as model amphoteric compounds, in their corresponding isoelectric point.

A Computational Analysis of the Reaction of SO₂ with Amino Acid Anions: Implications for Its Chemisorption in Biobased Ionic Liquids

Molecules, 2022
We report a series of calculations to elucidate one possible mechanism of SO2 chemisorption in amino acid-based ionic liquids. Such systems have been successfully exploited as CO2 absorbents and, since SO2 is also a by-product of fossil fuels’ combustion,

A Systematic Review of Amino Acid-Based Adsorbents for CO₂ Capture

Energies, 2022
The rise of carbon dioxide (CO2) levels in the atmosphere emphasises the need for improving the current carbon capture and storage (CCS) technology. A conventional absorption method that utilises amine-based solvent is known to cause corrosion to process

Anodic Fluorination and Cathodic Michael Addition of Schiff Bases Bearing Trifluoromethyl and Ester Groups

Electrochemistry, 2021
Anodic fluorination of N-(diphenylmethyleneamino)-2,2,2-trifluoroethane and N-[bis(methylthio)methyleneamino]-2,2,2-triphenylethane in acetonitrile containing poly(HF) salt ionic liquids afforded monofluorinated products in moderate to good yields.

Rigorous non-isothermal modeling approach for mass and energy transport during CO2 absorption into aqueous solution of amino acid ionic liquids in hollow fiber membrane contactors

, 2021
In the current study, a rigorous modeling approach was used to develop a mathematical model for the non-isothermal absorption process of CO2 in hollow fiber membrane contactors (HFMC). Four amino acid-based ionic liquids (ILs) namely, tetramethylammonium

Changes in the gut microbiota of mice orally exposed to methylimidazolium ionic liquids.

PLoS ONE, 2020
Ionic liquids are salts used in a variety of industrial processes, and being relatively non-volatile, are proposed as environmentally-friendly replacements for existing volatile liquids.

CO2 Capture in Ionic Liquids Based on Amino Acid Anions With Protic Side Chains: a Computational Assessment of Kinetically Efficient Reaction Mechanisms

ChemistryOpen, 2020
Absorption and capture of CO2 directly from sources represents one of the major tools to reduce its emission in the troposphere. One of the possibilities is to incorporate CO2 inside a liquid exploiting its propensity to react with amino groups to yield ...
