Lignocellulosic biomass can become an important raw material for the production of polymers containing sugars. Glucose is the best known breakdown product of cellulose. However, the depolymerization of hemicellulose results in the formation of glucose, as well as other hexoses (mannose, galactose, rhamnose) or pentoses (xylose, arabinose). On the other hand, levulinic acid has been pointed out as a promising molecule with regard to sustainable chemicals, which can be produced from renewable resources such as lignocellulosic biomass. The α-angelica lactone (AL) can, in turn, be produced from levulinic acid through an intramolecular condensation process followed by dehydration, presenting itself as an important raw material for the synthesis of new polymers sustainable. This work has as main objective to investigate the valorization of sugars and their derivatives, present as major components in the aqueous fraction resulting from the liquefaction processes of the wood biomass, aiming at its use in the production of sustainable and biodegradable polymers, which can be applied to processes industrial in the pharmaceutical industry.
