| Abstract: |
| The DHP-xylan complex(DHPXC) was synthesized by using lignin dehydrogenated polymer(DHP) and xylan as raw materials and cooked by kraft pulping method. The infrared spectra and 13C-NMR spectra were used to identify the chemical structure of the obtained complex and its degraded products after kraft pulping. The results indicated that there were a lot of xylan in the acid-insoluble substances. Xylan was linked with lignin by LCC linkage. There were certain amount of structures with double bonds and γ-CH2OH on side chains of lignin after cooking. The β-β was the main linkage between the structural units of residual lignin. There were also some β-5 and β-O-4 structures. |
