Changes in lignin structure and composition during OrganoCat pretreatment. a 2D HSQC spectra of Miscanthus raw material and b pulp (oxalic acid, 140 °C highlighting the signals used for quantification. c Chemical structure of examined lignin linkages and monomers. d Lignin composition showing the Guaiacyl (G) and Syringyl (S) molar distribution for Sida, Beech wood, and Miscanthus. e Molar distribution of lignin ether bonds for Sida, Beech wood, and Miscanthus. Values are expressed as mean ± standard deviation; n = 3
