This work focuses on spectroscopic characterization of lignin extracted from wood liquefaction residues. The aim of the research was to evaluatethe influence of the amount of the solventand the raw material typeused for liquefaction on the spectral parameters of the lignin isolated from liquefaction residues.Different types of biomass assortments were liquefied according to the previously described procedures.The amount of the propylene glycol used as the liquefying agent has been modified. The lignin isolated from the residues after wood liquefaction process has been subjected to spectroscopic studies. Absorption spectra were obtained using a double-beam spectrophotometer. As a reference the lignin extracted from standard untreated samples was used. Based on the research it has been concluded thatthe amount of the solvent and the raw material type do not have significant influence on the spectral properties of liquefied wood products.
