| Abstract: | The dissolution of lignin and major ploysaccharides from sulfonated chemimechanical pulp(SCMP) of L. gmelini during sulfonation and defibration. the tharacte ristics of lignin and bleachability of larch SCMP were studied using gas chromatography (GC), IR, UV spectrometry, 1H- NMR. 13C-NMR and chemical analyses. |
