US 2025/0243232 A1 · GLYONIC LIQUIDS AND USES THEREOF

Abstract

The present invention provides ionic liquids (ILs) comprising a carbohydrate anionic moiety and a cationic counter-ion moiety (Q+) and methods for producing and using the same. In one particular embodiment, the carbohydrate anionic moiety portion of ILs of the present invention is of the formula: [G-L]− I wherein G is selected from the group consisting of a monosaccharide, a disaccharide, a trisaccharide, and a derivative thereof; and L is a moiety selected from the group consisting of: wherein each of Ra, Rb, and Rc is independently hydrogen, C1-18 alkyl, or C2-20 mono- or di-unsaturated alkenyl; A− is —CO2−, —PO3H−, or —SO3−; and each of * marked carbon atom is independently a chiral center when said carbon atom has four different groups attached thereto.
