Abstract

Abstract: By means of FTIR, the cellulose of walnut shell was liquefied and degraded under acid catalyst in the presence of phenol firstly. The variation of main chemical groups of liquefied and degraded products of cellulose as a function of reaction time based on FTIR characteristics was discussed in this paper. Results from FTIR spectra showed, although the course of reaction could be described by liquefaction, the process was a degradation of cellulose essentially; cellulose was degraded to low molecular fragments such as oligosaccharides, and the pyranoid ring was broken at last.

Key words: walnut shell, cellulose, degradation, FTIR
