Abstract
The design of environmentally friendly methodologies has been the driving force of scientists in recent years. In particular, the use of biomass-derived materials, green solvents and alternatives techniques has been investigated for the production of platform molecules and chemicals such as furfural, hydroxymethylfurfural... Several green chemistry approaches that target advanced synthesis and processes will be presented. All these approaches include the production of (i) furfural and derivatives from D-xylose, xylane and hemicellulose using alternative technologies; (ii) hydroxymethylfurfural and derivatives from D-glucose/D-fructose; (iii) 2,5-diformylfuran from D-fructose. All the process used alternative technologies (eg. microwave irradiation, high temperature/ pressure???) in batch and continuous flow via homogeneous and heterogeneous catalysis.[1-8] Conception, synthesis and physicochemical properties will be detailed.
