Eng.) - Asian Institute of Technology, 2013 Summary: In this research, the lignin reactivity during alkaline delignification was quantitatively investigated focusing on the effect of the structural differences between syringyl and guaiacyl aromatics nuclei as well as various alkaline conditions on theÝ-O-4 bond cleavage rate.Moreover, the lignin compounds with 2-carbon side chains were studied to avoid the complex kinetics caused by the propanol diastereomers which hydrolyze at different rates and the Ü{u2013}and Þ{u2013}hydroxyls both participating in the displacement reaction.The presence of a syringyl nucleus, increasing of the reaction temperature as well as higher alkaline concentration influenced the increasing of the reaction rate.
