    • A method according to the present invention is a method for producing an ionic liquid from a molten salt solution containing a molten salt constituted by combining the cation portion and the anion portion, the ionic liquid containing the molten salt as a main component, the method comprising: removing water from the molten salt solution, the step of removing the water including adding a compound in the molten salt solution, the compound being represented by General Formula (1): where at least two of R1 to R4 are a C1 to C8 alkoxy group(s), the rest of R1 to R4 are a hydrogen atom(s) or a C1 to C8 alkyl group(s). By this, it is possible to remove water from the molten salt solution regardless of whether the molten salt solution is hydrophilic or hydrophobic. The present invention provides a method of producing an ionic liquid, which method can remove water from any kind of ionic liquid economically, easily, and quickly.
    • 根据本发明的方法是一种从包含熔融盐的熔融盐溶液中制备离子液体的方法,该熔融盐溶液是通过将阳离子部分和阴离子部分,含有熔融盐作为主要成分的离子液体组合而成的,该方法包括 :从熔融盐溶液中除去水,除去水的步骤,包括在熔融盐溶液中加入化合物,该化合物由通式(1)表示:其中R 1至R 4中的至少两个为C 1至C 8烷氧基 基团,R 1至R 4的其余部分为氢原子或C 1至C 8烷基。 由此,无论熔融盐溶液是亲水还是疏水,都可以从熔融盐溶液中除去水分。 本发明提供一种生产离子液体的方法,该方法可以经济,容易和快速地从任何种类的离子液体中除去水分。
