Chemical structure of lignin originating fine chemicals (vanillin, syringaldehyde, vanillic acid, and syringic acid), employed lignin model compounds (compounds 1E and 1T), phenolic compounds (TMPh and Valc) employed in the O2 system, and degradation products (veratraldehyde, veratric acid, and guaiacol). Numbering of carbons for aromatic nucleus and side-chain are shown in compound 1E
