Green chemistry emphasizes designing novel routes to overcome health and environmental
problems that occur during a chemical reaction. Green solvents are used in place of conventional solvents
that are hazardous to both human and the environment. Solvents like water, ionic liquids, supercritical
CO2, biosolvents, organic carbonates, and deep eutectic mixtures can be used as green solvents.
The review focuses on the properties, applications, and limitations of these solvents.
