dc.description.abstractWillow biomass was subjected to different pretreatmentconditions with triethylammonium hydrogen sulfate as solvent, andthe produced lignin solutions were treated by oxidation either homo-geneously using H2O2as oxidant or by heterogeneous catalysis usingTiO2. Lignin, residual lignin, oil, and the recovered ionic liquid (IL)were characterized in order to determine the effects of each treatment.Lignin was successfully extracted and depolymerized by oxidation andcharacterized by ATR-IR, HPSEC, and py-GCMS. The obtained oilwas characterized by GCMS; it was composed mainly of acids derivedfrom the sugar and lignin fractions, the TiO2catalyzed oils being richerin phenolic derived compounds than sugar fractions. Thefinal ionicliquid was characterized in order to determine its suitability to bereutilized.es_ES
