A Search for Natural Hydrophobic Deep Eutectic Solvents Based on Natural Components

ACS Sustainable Chemistry & Engineering, Journal Year: 2019, Volume and Issue: 7(3), P. 2933 - 2942

Published: Jan. 2, 2019

Deep eutectic solvents (DESs) based on terpenes are identified and characterized. 507 combinations of solid components tested, which results in the identification 17 new hydrophobic DESs. Four criteria introduced to assess sustainability these DESs from a chemical engineering point view. These include viscosity smaller than 100 mPa·s, density difference between DES water at least 50 kg·m–3 upon mixing water, low transfer phase minor no pH change. The show that five natural satisfy criteria; thymol coumarin (2:1), menthol (1:1), (1:2) 1-tetradecanol (1:2), thus promising can be considered as deep solvents, have potential environmentally friendly. A selected group were used for extraction riboflavin water. They all higher removal comparison decanoic acid:tetraoctylammonium bromide (2:1). highest efficiency 81.1%, was achieved with DecA:Lid

Phenolic hydrogen bond donors in the formation of non-ionic deep eutectic solvents: the quest for type V DES

Chemical Communications, Journal Year: 2019, Volume and Issue: 55(69), P. 10253 - 10256

Published: Jan. 1, 2019

Mixtures of non-ionic compounds have been reported as DES but most are just ideal mixtures. In the thymol-menthol system, an abnormal strong interaction was identified stemming from acidity difference phenolic and aliphatic hydroxyl groups. This type is found to be key prepare DES, that may classified V.

Deep Eutectic Solvents for Boosting Electrochemical Energy Storage and Conversion: A Review and Perspective

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(22)

Published: March 11, 2021

Abstract The pursuit of sustainable energy utilization arouses increasing interest in efficiently producing durable battery materials and catalysts with minimum environmental impact. As green, safe, cheap eutectic mixtures, deep solvents (DESs) provide tremendous opportunities open up attractive perspectives as charge transfer reaction media for electrochemical storage conversion (EESC). In this review, the fundamental properties DESs are first summarized. Then, important roles that play various EESC technologies including advanced electrolytes batteries/supercapacitors, preparation electrode catalysts, extracting agents recycling systematically reviewed. A particular focus is placed on understanding structure–composition–property–performance relationships. Finally, challenges controllable design applications future developments presented. This review expected to shed light developing next‐generation systems.

Revisiting greenness of ionic liquids and deep eutectic solvents

Green Chemical Engineering, Journal Year: 2021, Volume and Issue: 2(2), P. 174 - 186

Published: Feb. 6, 2021

Green solvents are one of the hot topics green chemistry. Ionic liquids (ILs) and deep eutectic (DESs) deemed as to a certain extent, they have been applied in many areas, such dissolution, separation, catalysis, electrochemistry material synthesis. However, greenness ILs DESs should be revisited because more evidences shown that not always green. In this perspective, besides reported merits, disadvantages problems some DESs, instability, volatility, hygroscopicity, toxicity, flammability, regenerability, cost, energy consumption impurities discussed. Moreover, 13 strategies avoid increase proposed. Comparison is further conducted. This perspective provides new viewpoints on DESs.
