Abstract: The composition of the pyrolyzate of untreated and H3PO4-impregnated
corncobs and straw was studied by g.I.c.—mass spectrometry. The major
products of thermal degradation were 2-furaIdehyde, acetic acid, Ievoglucosenone, and the other significant compounds were identified as 3-hydroxy-2-penteno-l,5-lactone, levulinic acid, guaiacol, acrylaldehyde, and 4-hydroxy-3-methoxy-l-vinylbenzene. The treatment of corncobs and straw with
acid catalyst before the pyrolysis showed expressive changes of amount and
distribution of pyrolytic products. Substantial departures between the composition of the pyrolyzate of corncobs and straw were not found. The results of
dynamic thermal analysis (TG, DTG, DTA) are also reported.
