If you had to use 1HNMR to verify that you actually synthesized vanillyl alcohol from vanillin, describe at least two key differences in the 1HNMR spectra of these two compounds that would support your claim. From: NMR Database of Lignin and Cell Wall Model Compounds. The lower boiling point of the product may be contributed to impurities in the solution and side reactions that occurred during the addition of NaBH4. The structures of vanillin-based monomers were characterized by NMR and FTIR. Vanillin and vanillyl alcohol were modified into methacrylated derivatives. Use the HNMR and CNMR of vanillin and vanillyl alcohol to identify the various protons and carbons on the two structures. In addition, two bio-based diepoxy monomers were synthesized from vanillyl alcohol (DGEVA) and gastrodigenin (DGEGD) and characterized via 1H-NMR, 13C-NMR, FTIR, MS, and GPC.
