Effect of reaction media concentration on the solubility and the chemical structure of lignin model compounds

In order to investigate the impact of the concentration reaction medium on the structure of lignin model compounds (DHPs = dehydrogenation polymers), we synthesized lignin model compounds with and without xylans at various concentrations. Results indicate that the frequency of β-alkyl aryl ether bonds, molecular weight and solubility of DHP increase with the concentration of the reaction medium in presence of xylans.
