IONIC LIQUIDS THAT UNDERSTAND CATIONS THAT CONTAIN NITROGEN.

摘要

Use, as a solvent, of an ionic liquid comprising an anion and a cation characterized in that the cation is a cation containing tertiary nitrogen with the formula (I) N + HRR'R '' (I) wherein R is a group hydrocarbyl which is alkyl substituted with one or more hydroxyl substituents, and the hydroxyalkyl group contains 1, 2, 3, 4, 5 or 6 carbon atoms; and R 'and R' 'are each a hydrocarbyl group which is alkyl optionally substituted with one or more substituents selected from nitrogen-containing functional groups (including nitrile, nitro or amino or other basic nitrogen-containing functional group), optionally interrupted alkyl by one or more ether, alkoxy and hydroxyl bonds; The anion is selected from carboxylates, alkyl carboxylates, bis (trifluoromethylsulfonyl) imide, carbonate, chloride, hydrogen carbonate, sulfate, hydrogen sulfate, silicate, methanesulfonate, trifluoromethanesulfonate, hexafluorophosphate and tetrafluoroborate.
