Imidazole two-functionized room temperature inonic liquid and its preparing method

Abstract

This invention relates to a room temperature ionic liquid with dual functional imidazolyl and its preparation. Through reaction of functional imidazole and alkylogen that contains functional group, this ionic liquid first produces dual functional ionic liquid of which anion is halogen anion, then through anion exchange, obtains dual functional ionic liquid that contains different anion. The ionic liquid of this invention has fine heat stability, is stable for water and air, possesses satisfactory electrochemistry character, can be used as electrolyte for electrochemistry research. In orthodox acid catalysis reaction, it not only can be used as catalyst, but also can be used as reaction medium. Meanwhile, it can be used as medium that can separate and extract.

[0001] The invention relates to an imidazole-based bifunctional room temperature ionic liquid and a preparation method thereof Background technique

[0002] In recent years, room temperature ionic liquids have attracted extensive attention from academia and industry as a "green solvent" and reaction medium. Room temperature ionic liquids (RTILs) refer to salts that are liquid at room temperature or near room temperature, mainly composed of organic cations and inorganic and organic anions. As early as the early 1980s, the British BP company and the French IFP research institute had begun to explore the possibility of room temperature ionic liquids as solvents and catalysts. So far, room temperature ionic liquids have been used in catalytic reactions, organic synthesis, separation analysis, and solid lubrication. It has been widely used in many fields of electrochemical research. As a new class of green solvents, room temperature ionic liquids have the follow...
