摘要：

Moso bamboo (Phyllostachys pubesens) was liquefied in phenol with sulfuric acid (H2SO4) or hydrochloric acid (HCl) as the catalyst. The effects of the weight ratio of phenol to bamboo and the kind and concentration of catalyst used on the characteristics of the liquefied bamboo were investigated. The results showed that liquefaction in phenol with H 2SO4 had a better effect than with HCl as the catalyst. The former had less un-liquefied residue, more non-volatile matter, and more combined phenol than the latter. When comparing the liquefaction effect of the weight ratio of phenol to bamboo, a weight ratio of 3/1 had less un-liquefied residue and non-volatile matter, and a lower viscosity of liquefied products than with a weight ratio of 2.5/1. The FT-IR spectra showed that phenol reacted with the decomposed chemical components of bamboo and formed derivatives after liquefaction. The GPC analysis showed that liquefied bamboo had a weight average molecular weight of 1867-3550.
