Título: | Continuous flow nanocatalysis: reaction pathways in the conversion of levulinic acid to valuable chemicals |
Autor: | Bermúdez Menéndez, José Miguel CSIC; Menéndez Díaz, José Ángel CSIC ORCID ; Romero, Antonio A.; Serrano, Elena CSIC; Garcia-Martinez, Javier; Luque, Rafael | Fecha de publicación: | jul-2013 | Editor: | Royal Society of Chemistry (UK) | Citación: | Green Chemistry 15(10): 2786-2792 (2013) | Resumen: | [EN] The selective production of 2-methyltetrahydrofuran from levulinic acid has been effectively conducted using designed Cu based catalysts and compared with a commercial Pd/C system under microwave irradiation. Optimised conditions for the most active catalysts Cu-MINT (>90% conversion, 75% selectivity to MTHF) and Pd/C (78% conversion, 92% selectivity to MTHF) were further translated into a continuous flow process using the proposed catalysts to find out the deactivation of Cu-MINT under flow conditions (79 vs. 13% conversion with a switch in selectivity to products after 30 min in flow), the high stability of Pd/C (73 vs. 70% conversion at stable selectivity under analogous conditions to those of Cu-MINT) but, most importantly, different relevant pathways to valuable products from levulinic acid depending on the type of catalyst employed. | Versión del editor: | http://pubs.rsc.org/en/content/articlelanding/2013/gc/c3gc41022f | URI: | http://hdl.handle.net/10261/82793 | DOI: | 10.1039/C3GC41022F | E-ISSN: | 1463-9270 |
