Solid state nuclear magnetic resonance, 4(3), 143-151.http://hdl.handle.net/10400.13/3375The thermal decomposition of cork has been studied by Fourier transform infrared (FTIR) spectroscopy and 13C solid-state nuclear magnetic resonance (NMR) spectroscopy with cross-polarization and magic-angle spinning (CP-MAS), high-power ‘H decoupling (HPDEC) and cross-polarization depolarization-polarization (CPDP). Waxes and other soluble components of cork begin to decompose at ca. 150°C. This is accompanied by partial decomposi tion of suberin, probably initiated at the points of attachment to the cell wall. The carbohydrates begin to decompose at ca. 200°C. The decomposition of lignin begins at 250-3OO”C, while suberin undergoes further degradation. Significant amounts of coke are formed in the process. At 400°C cork has been transformed into coke with traces of partially decomposed suberin. The thermal decomposition of cork is dependent on the calcination time, particularly in the 200-350°C range.engCorkThermal decomposition of cork13C Solid-state nuclear magnetic resonanceFourier transform infrared studies.Faculdade de Ciências Exatas e da Engenharia13C solid-state nuclear magnetic resonance and Fourier transform infrared studies of the thermal decomposition of corkjournal article10.1016/0926-2040(94)00039-F
