NMR Spectrum
Prediction： Figure 6. Comparison of ]H NMR spectra of the reaction between HMF and [EMIMJOAc (1 : 1 molar ratio) in DMSO- 6 at 80 掳C over the initial 25 minute period. This spectral overlay in the most characteristic region shows the gradual decreasing of the intensities (normalized by the C6Me6 internal standard) of the peaks for HMF (6.59 ppm, A line) and intermediate II (6.73, 6.39, 6.26 ppm, B lines), with the concomitant increasing of DHMF (6.48, 6.29, 6.19, 5.72 ppm, C lines). A small shoulder peak at 5.74 with a constant intensity is the residual solvent (CH2CI2) brought from the IL.
