This experiment describes the synthesis of a family of fragrances, including the commercially important Methyl Diantilis, that were covered by a U.S. patent in 1987.

Data compiled by: NIST Mass Spectrometry Data Center, William E. Wallace, director CAS Number Search, Compound Synonyms I These combine to give a single peak because they are both in exactly the same environment. Citation: El-Sayed AM 2019. 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. The thermomechanical properties of cured DGEVA and DGEGD thermosets were compared to those of the cured DGEBG and commercially available thermosets to determine the effect of the methoxy moiety. 53:6971-6976. 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. » NMR Kovats Ions Semiochemicals & Taxa Synthesis Control Invasive spp. The reduction of vanillin to vanillyl alcohol has been documented for only a few species of fungi. From: NMR Database of Lignin and Cell Wall Model Compounds. Vanillyl-alcohol oxidase (EC 1.1.3.38) ... 1 H-nuclear magnetic resonance (NMR) spectra were recorded on a Bruker AMX 400-MHz spectrometer at 24°C. The thermomechanical properties of cured DGEVA and DGEGD thermosets … Use the HNMR and CNMR of vanillin and vanillyl alcohol to identify the various protons and carbons on the two structures. Vanillin and vanillyl alcohol were modified into methacrylated derivatives.
