Analysis of Chinese larch (L. gmelini) SCMP bleachability

Abstract

The dissolution of lignin and major ploysaccharides from sulfonated chemimechanical pulp (SCMP) ofL. gmelini during sulfonation and defibration, the tharacteristics of lignin and bleachability of larch SCMP were studied using gas chromatography (GC), IR, UV spectrometry, ’H-NMR, “C-NMR and chemical analyses.
