| 其它 | Enzymatic hydrolysis (EH) lignin from the cornstalks residue was separated by two methods. The EH lignin was analyzed with respect to molecular weights, IR, UV spectra and 13C-NMR spectroscopy. The results indicated that EH lignin had lower molecular weight than the milled wood lignin and contained many active chemical groups. There were different absorbance peaks at 1700 cm-1 and 1328 cm-1 on the IR spectra of EH lignin. It was showed that the non-conjugated carbonyls were existed in the EH lignin. The absorbance appeared in 210 nm, 280 nm and 310 nm in UV spectra of the EH lignin, the fact indicated that the EH lignin was an unsaturated polymer. According to the 13C-NMR, EH lignin belongs to "GSH" type of lignin, and it was composed mainly of β-O-4 ether bonds together with β-5 and β-1 carbon-carbon linkages between the lignin structural units. |
