摘要：

Lignins obtained by delignification of Pinus pinaster and Eucalyptus globulus wood with acetic acid were characterized by elemental analysis, FTIR and H-1 and C-13 NMR spectroscopy. Eucalyptus lignin of type G. The observed structural differences explain the difference between their reactivities with formaldehyde. Both reactivities were low, however, making these lignins poor raw materials for the preparation of adhesives.
