The invention relates to an onium salt, a liquid composition containing the onium salt and cellulose, and a method for recovering cellulose. The invention makes it possible to provide an onium salt having an extremely high ability to dissolve cellulose at temperatures of 100° C. or lower. It also makes it possible to provide a liquid composition containing this onium salt and cellulose, as a composition suitable for the recovery of cellulose, and a method for recovering cellulose efficiently by using such a liquid composition containing the onium salt and cellulose.

New hydrophobic ionic liquids consisting of trialkyl(2-methoxyethyl)ammonium ([R1R2R3NCH2CH2OCH3]+, R1, R2, R3 = CH3 or C2H5) cation and perfluoroethyltrifluoroborate ([C2F5BF3]−) anion were prepared by neutralization of aq. [R1R2R3NCH2CH2OCH3][OH] with aq. H[C2F5BF3]. The new [C2F5BF3]−-based ionic liquids show much lower melting points and viscosities (58–86 cP at 25 °C), hence higher ionic conductivities, than the [BF4]−-based ones.
通过用 H[C2F5BF3]中和[R1R2R3NCH2CH2OCH3][OH]等离子,制备了由三烷基(2-甲氧基乙基)铵([R1R2R3NCH2CH2OCH3]+,R1、R2、R3 = CH3 或 C2H5)阳离子和全氟乙基三氟硼酸盐([C2F5BF3]-)阴离子组成的新型疏水性离子液体。与基于[BF4]的离子液体相比,基于[C2F5BF3]的新型离子液体显示出更低的熔点和粘度(25 °C 时为 58-86 cP),因此离子电导率更高。
Design of Cellulose Dissolving Ionic Liquids Inspired by Nature
Stimulating the hunger of enzymes: The design of an ionicliquid that has the ability to dissolvecellulose has been attempted from the viewpoint of a cellulase. N,N‐diethyl‐N‐(2‐methoxyethyl)‐N‐methylammonium alanine ([N221ME][Ala]) is a good solvent for cellulose. Dissolution in [N221ME][Ala] converts the crystalline structure of cellulose from Type I to II, which is known to be a form easily digested

A compound [I] such as ammonium N-(chlorosulfonyl)-N-(fluorosulfonyl)imide is reacted with hydrogen fluoride to obtain a compound [II] such as ammonium N,N-di(fluorosulfonyl)imide. The obtained compound [II] is reacted with an alkali metal compound or the like to obtain a compound [IV] such as an N,N-di(fluorosulfonyl)imide alkali metal salt.
