Abstract

In this research, the characteristics of CMP dioxane lignin (hardwood origin) and soda bagasse lignin (ethanol soluble fraction) and dioxane lignin of bagasse were studied using gel permeation chromatography, gas chromatography-mass spectrometry and 13C NMR spectroscopy and DFRC degradation procedure. The results indicated that the main structural units in lignins are phenyl propane skeletons bonded at β-O-4 positions.
