Description
Technical Field

Background
Ionic liquids (or ionic liquids) are liquids that are entirely composed of ions, such as KCI at high temperatures, with KOH in the liquid state, where they are ionic liquids. Materials composed of ions that are liquid at or near room temperature are called room temperature ionic liquids, room temperature molten salts (room temperature ionic liquids are often accompanied by the presence of hydrogen bonds, defined as room temperature molten salts being somewhat marginal), organic ionic liquids, and the like, and there is currently no uniform name but there is a tendency for ionic liquids to be abbreviated. In an ionic compound, the acting force between anions and cations is coulombic force, the magnitude of which is related to the charge quantity and radius of the anions and cations, and the larger the ionic radius is, the smaller the acting force between the anions and cations is, and the lower the melting point of the ionic compound is. Certain ionic compounds have large anionic and cationic volumes and loose structures, resulting in low forces between them, so that the melting point approaches room temperature.
