Analysis on Cellulose Crystalline and FTIR Spectra of Artocarpus heterophyllus Lam Wood and Its Main Chemical Compositions

摘要

Cellulose crystalline and FTIR spectra of Artocarpus heterophyllus Lam wood and its main chemical compositions were analyzed.The result showed that the FTIR spectra of original wood samples from Artocarpus heterophyllus Lam wood present the same basic structure of all wood samples, the FTIR spectra of extracted wood samples were compared with the original wood sample, some of their absorption peaks of the band shifted to long or short wave, the wood and the solvent had little chemical reaction in the extracting process. FTIR spectra crystalline index of nitric acid-ethanol cellulose from Artocarpus heterophyllus Lam wood is NO'KI_1 0.984, O'KI_2 1.59, X-ray diffraction crystalline index of nitric acid-ethanol cellulose from Artocarpus heterophyllus Lam wood is 0.794.
