Fig. 3 — (1) the hydroxyl resonance at 5.57 ppm was selectively irradiated. The integral of the irradiated (negative, peak 10) peak was assigned a value of 100%. The absolute values of other NOE intensities were measured relative to peak 10. (2) The methyl resonance of acetate at 1.20 ppm was selectively irradiated. (3) Normal ¹H NMR spectrum. The molar ratio of benzyl alcohol to [EMIM] OAc in the mixture was 10:1. s-Trioxane was used as an internal standard at 5.11 ppm.
