Abstract

The effects of various solvents, including phenol, ethylene glycol (EG) and ethylene carbonate (EC), and different liquid ratios on the liquefaction of bamboo, have been studied systematically in this paper. The processes were catalyzed by hydrochloride acid at 180 °C in autoclaves for different reaction times. The results show that phenol is the optimum solvent for bamboo liquefaction with a yield up to 99%. The Fourier transform-infrared (FT-IR) analyses of the residues show that cellulose, hemicelluloses and lignin are almost decomposed when using phenol as solvent. The gel permeation chromatography (GPC) results of the liquid products show that the high molecular weight of bamboo decreases significantly to around 1800 g mol-1after liquefaction. The gas chromatography and mass spectrometry (GC-MS) analysis shows that low boiling point products of liquefied bamboo are similar regardless of the type of solvent used.
