Abstract
(EN)
Provided is a synthesis method for an imidazole ionic liquid 1-allyl-3-vinylimidazolium acetate, comprising: first carrying out one-step reaction between N-vinylimidazole and allyl chloride to obtain an ionic liquid intermediate 1-allyl-3-vinylimidazolium chloride, and then carrying out anion exchange with potassium acetate using the intermediate to obtain 1-allyl-3-vinylimidazolium acetate ([AVIM][OAc]). The ionic liquid 1-allyl-3-vinylimidazolium acetate can be used as a solvent, and can be used for dissolving biological macromolecules such as starch and cellulose.
(FR)
L'invention concerne un procédé de synthèse d'un liquide ionique d'imidazole, l'acétate de 1-allyl-3-vinylimidazolium, consistant à : réaliser d'abord une réaction en une étape entre le N-vinylimidazole et le chlorure d'allyle pour obtenir un intermédiaire liquide ionique, du chlorure 1-allyl-3-vinylimidazolium, puis effectuer un échange d'anions avec de l'acétate de potassium à l'aide de l'intermédiaire pour obtenir de l'acétate de 1-allyl-3-vinylimidazolium ([AVIM] [OAc]). Le liquide ionique, l'acétate de 1-allyl-3-vinylimidazolium peut être utilisé en tant que solvant, et peut être utilisé pour dissoudre des macromolécules biologiques telles que l'amidon et la cellulose.
