The process of crystallization is completed by cooling in an ice-water bath. Finally, reactants and products will be characterized using IR and 1H NMR spectroscopy. vanillyl alcohol. SUMMARY Student Name: Fischer Davis Partner Name: Lauren Fehr Lab Section: CHEM 253-021 TA Name: Sheryl Sharma Expt. … Renewable polymers were prepared from these vanillin-based monomers. Samples were prepared by freeze-drying the isolated products obtained from HPLC separations and dissolving the products in CD 3 OD or D 2 O. We then analyzed different NMR's for vanillin and vanillyl alcohol and determined that they were an accurate representation of the various carbons and protons found in the two structures. 1H and 13C NMR spectra were consistent with those previously reported in the literature.4 3.2. The melting point of the vanillyl alcohol produced was 97°C as compared to the actual melting point of vanillyl alcohol at 115°C. Vanillyl alcohol as a lignin model compound was subjected to the same modification procedure with lignin to uncover the mechanism by FTIR and nuclear magnetic resonance (NMR) analysis, indicating there are three potential reaction sites: C C, C O and CH 2-, among which C C is likely to form a cross-linked network.
