LIGNIN STRUCTURAL ANALYSIS OF THE TRIPLOID OF CHINESE ASPEN
The two-stage method was chosen as the isolation methods for the lignin preparation from the triploid of Chinese Aspen. The molecular weight distribution of the lignin sample was studied by GPC. The quantity-average molecular weight and mass-average molecular weight of lignin were obtained. The 31P-NMr spectra of phosphorized raw material lignin were achieved. The contents of aliphatic OH, total phenolic OH, and COOH in the lignin molecules were analyzed and compared.
