Ionic salt is a liquid salt that substitutes for typical organic solvents due to qualities like low volatilization and flammability. They are a well-known substance that turns into liquid at temperatures below 100 degrees Celsius. Ionic liquids are used in industries for lubrication and cleaning, cosmetics and personal care goods, medicine, cleaning, and cooking. Many ionic liquids have good thermal stability and low flammability due to their low vapor pressure at room temperature. These characteristics might enable their use in space and increase the safety of high-temperature solvent applications, such as those found in batteries. However, it should be emphasized that many Ionic liquids can still be distilled, albeit under harsh conditions.
Furthermore, they have better thermal and electrical conductivities than standard laboratory solvents and bigger electrochemical windows because Ionic liquids are made entirely of ions. As a result, they have found use as electrolytes and heat transfer fluids and can effectively disperse heat generated during a process. Ionic liquids, in particular, have been employed to improve catalyst recovery and product separation in various industrial processes by forming biphasic systems. Their solvation properties are heavily determined by the ions' ability to behave as hydrogen bond acceptors/donors and the degree of anionic charge delocalization.
