To elucidate these secondary reactions that occur during the pyrolysis of biomass, the analytical pyrolysis of 4-hydroxybenzaldehyde (HBA), vanillin (VL), syringaldehyde (SA) and veratrumaldehyde (VA) was performed via pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and the mechanisms for formation of secondary products were evaluated. Four pyrolysis products from SA and eleven pyrolysis products from VA were identified, while only two pyrolysates were detected from HBA and VL. On the basis of these results, several major pyrolysis mechanisms were proposed. The most common pyrolysis reactions involved the homolytic elimination, and addition of \u00b7H, \u00b7OH, \u00b7CHO, and \u00b7OCH_3, while the homolytic elimination of methyl group from methoxy group, and rearrangement of the methoxy group occurred infrequently. Furthermore, benzaldehydes with a phenolic hydroxyl group were stabilized by conjugation of the aromatic ring with the phenolic\u2013OH, and fewer pyrolysis products were produced than were obtained from compounds with non-phenolic benzyl alcohol groups, such as VA.", "subitem_description_type": "Abstract"}, {"subitem_description":
