BIPHASIC HYDROGENATION OF EUGENOL WITH RUTHENIUM AND RHODIUM NANOPARTICLES STABILIZED IN IONIC LIQUIDS
ABSTRACT The purpose of this study was to evaluate on the catalytic activity nanostructured systems of ruthenium and rhodium stabilized in ionic liquids derived from imidazole: IL1= butylmethyllimidazole tetrafluoroborate [BMIM][BF4] and IL2= butylmethylimidazole hexafluorophosphate [BMIM][PF6] in t...
