|[en] The non-energetic valorization of renewable resources using efficient and eco-friendly methodologies is the central axis of the “green chemistry” concept. In particular, the chemical conversion of carbohydrates arising from the hydrolysis of non-edible vegetable feedstock (i.e., lignocellulosic biomass and streams) is a widely explored thematic for the production of new high-added value materials.
In this context, we report here on the development of a microwave heating methodology for the efficient production of carbohydrate-based and lignin-based chemicals with relevant antioxidant and surface-active properties. New effective synthetic protocols minimizing wastes and energy-consumption are proposed. Enhanced yields and selectivities are achieved after a few minutes of microwave heating using heterogeneous catalysts. The benefits of this microwave approach are highlighted in terms of yields, atom efficiency, environmental factor, and carbon efficiency. Up-scaling assays are also discussed.
