Characterization of Organosolv Lignins using Thermal and FTIR Spectroscopic Analysis

  title={Characterization of Organosolv Lignins using Thermal and FTIR Spectroscopic Analysis},
  author={Rhea J. Sammons and David P Harper and Nicole Labb{\'e} and Joseph J. Bozell and Thomas J. J. Elder and Timothy G. Rials},
A group of biomass-derived lignins isolated using organosolv fractionation was characterized by FT-IR spectral and thermal property analysis coupled with multivariate analysis. The principal component analysis indicated that there were significant variations between the hardwood, softwood, and grass lignins due to the differences in syringyl and guaiacyl units as well as the different processing temperatures and times used to isolate the lignins. Partial least squares regression revealed that… CONTINUE READING
