Green Chemistry

Cellulose nanocrystals (CNCs) were successfully extracted from wood flour by a two-step process that comprised ethanol and peroxide solvothermal pretreatment and an ultrasonic disintegration process.

The enzymatic synthesis of panthenyl monoacyl esters was carried out by the direct esterification of fatty acids (e.g. lauric acid) with panthenol in sponge-like ionic liquids, as well as in deep eutectic mixtures, resulting in highly selective processes (i.e. near to 100% for the panthenyl monolaurate case).

This tutorial review highlights representative examples of ionic liquid (IL)-based (bio)catalytic systems integrating reaction and separation, as a tool for the development of sustainable chemical processes (e.g.IL/scCO₂biphasic reactors, membrane reactors, nanodrop systems, microfluidic devices, supported IL phases, sponge-like ILs,etc.).

Water and methanol affect the acid-catalysis conversion and the hydrogenation of the biomass derived furans via very different ways.

By utilizing the synergistic interaction between CuO and CeO₂, the stabilization of Cu⁺species at a metal–oxide interface is realized. H₂production is considerably suppressed, resulting in enhanced ethylene production with a high FE of 50.0%.
