摘要
Results of an in-depth analysis of Fourier-transform IR absorption spectra of hardwood and softwood dioxane lignins were reported. Correlations between absorption band intensities in initial and second-derivative spectra and 13C NMR spectroscopic data on the contents of guaiacyl and syringyl structural units were found. The found linear dependences enabled the contents of two types of phenylpropane units to be estimated in the range 0–100% with a relative error of ≤5%.
