Abstract
C-13 NMR spectroscopic studies of spruce oxygen-organosolv lignins ind icated the presence of muconic acid type structures. This confirms pre vious chemical analysis which reached the same conclusion. Resonances of the muconic acid structures in the NMR spectra of oxidized lignins were assigned using a model compound.
