The ether bond is introduced into the side chain of the cation of the ionic liquid to obtain an ether functionalized ionic liquid, which is widely used in the fields of catalysis science, separation technology, electrochemistry and the like. Common ether functional groups include short-chain ether bonds such as methoxymethyl (—CH2OCH3) and methoxyethyl (—CH2CH2OCH3), and long-chain ether groups such as alkoxymethyl (—(CH2)nOCH3).
