Liquefied Wood - Advanced Characterization of Lignin-Based Polymer

Jasiukaitytė, E. , M. Kunaver & C. Crestini
The object of our present work was a comprehensive characterization of the liquefied wood that could be used as a feedstock for the well­defined polymer synthesis. Beside the determination of overall hydroxyl value that was found to be dependent on time, the chemical characterization of liquefied wood samples was carried out by quantitative 31P, 13C NMR analysis and by monitoring the change of molar masses using size­exclusion chromatography. Liquefied wood samples for analysis were prepared...
