text: The FT-IR analysis of the solid residue left after the acetone dissolution (spectra not reported) showed a different distribution in the intensities of the -OH groups stretching (approximately 3400 cm-1) and the C-O stretching of the epoxide rings (approximately 905 cm-1, 830 cm-1, and 750 cm-1) and aliphatic alcohols (approximately 1020 cm-1) when compared with the same peaks in the acetone-soluble Lign EP spectrum.
