Outline of Final Research Achievements

To develop a unique thermally assisted chemolysis technique useful for structural analyses of a vide valiety of cross-linking polymers, the conversion reactions of thermocured epoxy resins in tetralinwere investigated in detail. The observed products directly reflected the cross-linking structure of the cured resins, whereas they are hardly observed in the pyrogram obtained by ordinary Py-GC measurements at the comparable temperature condition. This observation suggests the potential of chemolysis with tetralin useful for the analysis of the cross-linking structure of cured resin samples. Then the catalytic effect of titanium dioxide on pyrolysis of woody biomass was investigated mainly using tandem micro reactor-GC/MS. For the catalytic pyrolysis of cellulose, various aromatic hydrocarbons were observed as main products. This fact demonstrates that titanium oxide acts as a thermal catalyst to convert the oxygenated products into hydrocarbons through its thermal excitation.
