1-エチル-3-メチルイミダゾリウムクロリド

使用1-Ethyl-3-methylimidazolium chloride is an imidazolium chloride ionic liquid that can be used as:A starting material for the preparation of 1-ethyl-3-methylimidazolium chloride/tetrafluoroborate (EMI.Cl.BF4) molten salt for electrochemical studies.A solvent as well as catalyst for the depolymerization of oak wood lignin.A solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brnsted acid catalysts.

一般的な説明1-Ethyl-3-methylimidazolium chloride is an organic salt and a room-temperature ionic liquid (RTIL). It is used as a solvent in many organic reactions due to its unique properties like small vapor pressures, high thermal stabilities and ionic conductivities.

純化方法A yellow solution of impure 1-ethyl-3-methylimidazolium chloride (ALDRICH) (50 g) having a yellow color in deionized water (250 mL) was prepared. Decolorizing charcoal (3 g) was added to the yellow solution and the resulting mixture was heated at 65° C. for 24 hours. The solution was cooled to room temperature and filtered. The filtrate was colorless. The water was removed from the colorless filtrate using a lyophilizer. The resulting solid was then heated under a vacuum for 48 hours at 65° C. The product white solid was substantially pure 1-ethyl-3-methylimidazolium chloride (48 g).
