“…For example, many pharmaceutical production processes require ultralow levels of impurities to meet regulations, and so solvent recycling is not possible. However, for most applications, IL cleanup and reuse is crucial, so process considerations (use of other solvents for purification) and solvent properties (stability) need to be known …”

Sustainable solvents are a topic of growing interest in both the research community and the chemical industry due to a growing awareness of the impact of solvents on pollution, energy usage, and contributions to air quality and climate change. Solvent losses represent a major portion of organic pollution, and solvent removal represents a large proportion of process energy consumption. To counter these issues, a range of greener or more sustainable solvents have been proposed and developed over the past three decades. Much of the focus has been on the environmental credentials of the solvent itself, although how a substance is deployed is as important to sustainability as what it is made from. In this Review, we consider several aspects of the most prominent sustainable organic solvents in use today, ionic liquids, deep eutectic solvents, supercritical fluids, switchable solvents, liquid polymers, and renewable solvents. We examine not only the performance of each class of solvent within the context of the reactions or extractions for which it is employed, but also give consideration to the wider context of the process and system within which the solvent is deployed. A wide range of technical, economic, and environmental factors are considered, giving a more complete picture of the current status of sustainable solvent research and development.

“…PCMs, mainly referring to solid–liquid PCMs, have been proven to be more attractive for the use in large-scale thermal energy storage (TES) systems due to their relatively large latent heats with minimal volume change during the phase transition . PCMs lead to much higher energy storage density than HTFs, over a smaller temperature range, and consequently are of particular interest for applications with less substantial temperature variations . The most important factors of PCMs are the melting temperature and latent heat of fusion (also known as enthalpy of fusion), which determine the operating temperature range and thermal storage capacity, respectively …”

Ionic liquids (ILs) consisting entirely of ions exhibit many fascinating and tunable properties, making them promising functional materials for a large number of energy-related applications. For example, ILs have been employed as electrolytes for electrochemical energy storage and conversion, as heat transfer fluids and phase-change materials for thermal energy transfer and storage, as solvents and/or catalysts for CO2 capture, CO2 conversion, biomass treatment and biofuel extraction, and as high-energy propellants for aerospace applications. This paper provides an extensive overview on the various energy applications of ILs and offers some thinking and viewpoints on the current challenges and emerging opportunities in each area. The basic fundamentals (structures and properties) of ILs are first introduced. Then, motivations and successful applications of ILs in the energy field are concisely outlined. Later, a detailed review of recent representative works in each area is provided. For each application, the role of ILs and their associated benefits are elaborated. Research trends and insights into the selection of ILs to achieve improved performance are analyzed as well. Challenges and future opportunities are pointed out before the paper is concluded.

“…Ionic liquids (ILs) are broadly acknowledged as green extractants that adhere to sustainable chemistry because of their unique characteristics, such as viscosity, density, hydrophobicity, or hydrophilicity. , Moreover, they are excellent candidates for use in multidisciplinary areas, including electrochemistry, biochemistry, engineering, physical and analytical chemistry, due to their strong temperature stability and large electrochemical windows. ,− Consequently, they have received much consideration in study and usage during the last 20 years. − Nevertheless, as their usage has expanded, several ILs have had numerous flaws, including (1) high production costs, (2) organic solvents and complex methods are frequently needed for IL synthesis, (3) ILs are challenging to purify, and water and leftover ions (such as halogen ions) are challenging to eliminate, and (4) toxicities of ILs have been reported. , As a result, several initiatives have produced new green extractants in this scenario …”

Due to their low cost, biodegradability, and ease of preparation, deep eutectic solvents (DESs) are considered promising green alternatives to conventional solvents, as exploiting green solvents has been a research focus for achieving sustainable development goals. Most DESs in published studies are hydrophilic. On the other hand, the DES’s hydrophilicity restricts its practical applicability to just polar molecules, which is a vital disadvantage to this extractant. Hydrophobic DES (HDES) has been developed as a new extractant adept at extracting nonpolar inorganic and organic compounds from aqueous systems. Although there has been little research on HDESs (HDES publications account for <10% of DES), specific intriguing applications have been discovered, requiring investigation and comparisons. As a result, this review covers the applications of emerging HDES in detecting pesticide residues, food additives, contaminants in food packaging, heavy metals, separation and extraction processes in food. According to the available literature, HDESs have the potential to overcome the limitations of hydrophilic DESs and be used in a broader range of applications in food with greater efficiency, which has received little attention. HDES is expected to substitute a lot of harmful organic extractants used for analytical reasons (food chemistry) in the future. Besides, the limitations of HDES were reviewed, and future studies were provided. This will serve as a reference for green chemistry advocates and practitioners in food science who want to minimize pollution and improve efficiency and benefit from the further development of HDESs.
