Resumo: The identification of muconic acid type structures (MATS) in oxidised lignins employing 2D NMR spectroscopy was carried out. The primary database for MATS detection by single bond (1)H-(13)C (HSQC) and long-range (1)H-(1)H and (1)H-(13)C correlation (COSY and HMBC) NMR experiments was obtained with a series of model compounds: cis, cisand trans, trans-muconic acids and their methylated analogues and MATS derived from monomeric lignin model compounds oxidised by ClO(2). Additional information was obtained from the study of oxygen-organosolv lignin obtained from spent liquor after the spruce wood delignification with oxygen in an acetone-water solution. This work allowed the reliable assignment of MATS signals in the HSQC spectra of oxidised lignin and provides a methodology for detection and distinguishing of MATS from structurally similar moieties.
