NMR signal separation of ionic liquids by poly(sodium-p-styrenesulfonate)-assisted chromatographic NMR spectroscopy

Switchable product selectivity in dehydration of N-acetyl-d-glucosamine promoted by choline chloride-based deep eutectic solvents

“…In addition, the interaction between glycerol and GlcNAc was further demonstrated by DOSY NMR experiments, which is a pesedu-2D NMR spectroscopic technique with chemical shifts on the F1 dimension and diffusion coefficients (D) on the F2 dimension (shown in Figure S5 ). 44 The diffusion coefficients of glycerol and GlcNAc were 2.92 · 10 −10 m 2 /s and 1.85 · 10 −10 m 2 /s, respectively. The diffusion coefficients for glycerol and GlcNAc decreased to 1.54 · 10 −10 m 2 /s and 1.49 · 10 −10 m 2 /s when mixed.…”
