Use of deep eutectic solvents as catalyst: A mini-review

Green Processing and Synthesis, Journal Year: 2019, Volume and Issue: 8(1), P. 355 - 372

Published: Jan. 28, 2019

Abstract Deep eutectic solvents (DESs) exhibit numerous advantages over conventional ones used in several chemical and biochemical processes. Besides addressing most of the principles green chemistry, DESs can also act as catalyst depending on their nature. The use acid has such utilization at stoichiometric amount, non-toxicity, possibility recovery, similar or higher catalytic effect than itself alone, recyclability reusability without a significant loss activity. In this mini-review, state- of-the-art is presented. DESs, which show Lewis type acidity, Brønsted acidity other types influence various reactions including esterification, organic synthesis, glycolysis depolymerisation are presented roles discussed.

Everything You Wanted to Know about Deep Eutectic Solvents but Were Afraid to Be Told

Annual Review of Chemical and Biomolecular Engineering, Journal Year: 2023, Volume and Issue: 14(1), P. 141 - 163

Published: March 8, 2023

Are deep eutectic solvents (DESs) a promising alternative to conventional solvents? Perhaps, but their development is hindered by plethora of misconceptions. These are carefully analyzed here, beginning with the very meaning DESs, which has strayed far beyond its original scope mixtures Lewis or Brønsted acids and bases. Instead, definition that grounded on thermodynamic principles distinguishes between encouraged, types precursors can be used prepare DESs reviewed. Landmark works surrounding sustainability, stability, toxicity, biodegradability these also discussed, revealing piling evidence numerous reported thus far, particularly those choline based, lack sufficient sustainability-related traits considered green solvents. Finally, emerging DES applications reviewed, emphasizing most remarkable feature: ability liquefy solid compound target property, allowing use as liquid solvent.

Self‐Assembled Gels Formed in Deep Eutectic Solvents: Supramolecular Eutectogels with High Ionic Conductivity

Angewandte Chemie International Edition, Journal Year: 2019, Volume and Issue: 58(13), P. 4173 - 4178

Published: Jan. 25, 2019

1,3:2,4-Dibenzylidene-d-sorbitol (DBS), a simple, commercially relevant compound, was found to self-assemble as result of intermolecular noncovalent interactions into supramolecular gels in deep eutectic solvents (DESs) based on choline chloride combined with alcohols/ureas. DBS formed at loading 5 % w/v. Rheology confirmed the gel-like nature materials, electron microscopy and X-ray diffraction indicated underpinning nanofibrillar networks, differential scanning calorimetry showed DES liquid-like phase retained. The ionic conductivities were similar those unmodified DESs, thus proving phase. Gelation tolerant additives Li+ , Mg2+ Ca2+ ; resulting had electrolyte dissolved native DES. low-molecular-weight gelator is low-cost additive that forms DESs from readily available constituents, conductivity levels suitable for practical applications.
