Problems solved by technology

However, with the development of polymerizable ionic liquids, a single ionic liquid containing double bonds can no longer meet the needs of applications. More and more researchers have begun to synthesize multiple functional groups in one ionic liquid to form multifunctional ionic liquids.

Abstract

The invention provides chloridized 1-vinyl-3-amino-formyl methyl-imidazole bifunctional ionic liquid and a synthetic method thereof. The chloridized 1-vinyl-3-amino-formyl methyl-imidazole bifunctional ionic liquid is obtained by taking 1-vinylimidazole and 2-chloroacetamide as raw materials, acetone as a solvent and phenol as a polymerization inhibitor, and reacting at 45-55 DEG C. The synthesized ionic liquid enriches the variety of polymerizable ionic liquid, and provides more selections for the application of the ionic liquid in the fields of functional materials, catalysis, separation and the like. Besides, the synthetic method is simple in step, does not need special equipment and is lower in cost.

Description

technical field [0001] The invention relates to a bifunctional ionic liquid chlorinated 1-vinyl-3-carbamoylmethylimidazole with double bonds and amide groups and a synthesis method thereof, belonging to the technical field of functional materials and their preparation. Background technique [0002] Ionic liquids are composed of organic cations and inorganic anions or inorganic cations and organic anions, and are liquid molten salts at 100°C. Ionic liquids have almost no vapor pressure, are nonflammable, have high ion density and ion conductivity, and have good solubility for both inorganic and organic substances. Due to the adjustability of anions and cations, ionic liquids with desired properties can be obtained by changing the structures of anions and cations in ionic liquids. Therefore, ionic liquids have been widely used in separation chemistry, electrochemistry, organic chemistry, and even polymer chemistry in recent years. [0003] As an important branch of ionic liq...
