Study of Thermal Transformations of Cellulose by Curie-point Pyrolysis-gas chromatography-mass spectroscopy
The influence of different curie-point pyrolysis temperatures and times on the relative content of pyrolysis products obtained by curie-point pyrolysis from the microcrystalline cellulose was investigated by Curie-point Pyrolysis -gas chromatography-mass spectroscopy(CP-GC-MS). During the curie-point pyrolysis process, the main component of pyrolysis products was ievoglucosan all the time. Under pyrolysis temperature 300℃～370℃, sugar chemicals were obained from cellulose mostly. With the enhancement of pyrolysis temperature, the kind and content of chemicals of small molecular aldehyde,ketone ,which were made from the second reaction of monomer depolymerized from cellulose, were improved greatly. The chromatogram apexes of Py-GC-MS were not changed with the increment of pyrolysis time. Only the relative content of levoglucosan was decreased and the other products were kept the line or increased.The content of levoglucosan reached 73.07％ at the conditions of curie-point pyrolysis temperature 350, curie-point pyrolysis time is.
