Figure 1From: Comparison of vitrified and unvitrified Eocene woody tissues by TMAH thermochemolysis – implications for the early stages of the formation of vitriniteGeneric model for thermochemolysis of β-O-4 aliphatic-aryl ether bonds in guaiacyl lignin. Additional reactions also occur, resulting in the formation of numerous related and derived C9–C14 products. Modified after Filley et al [18].
