Resumen
The degradation of monosaccharides, though often undesired in lignocellulosic pretreatment, often lead to the formation of products with a higher value than the same sugars. In this chapter, detailed information related to monomer-based lignocellulosic biomass decomposition towards value added products using both water alone and a water/CO2 mixture is shown. The reaction mechanisms leadi to the rupture of the oligomers into monosaccharides, and then they break through dehydration reactions or aldol reactions. It will be demonstrated that CO2 plays a determinant role in the catalysis of hydrolytic reactions that take place in aqueous media. The optimum conditions for obtaining different products will be discussed, providing some indications on which configuration to adopt for increasing the selectivity of some reactions with respect to others.
