HIDROGENACIÓN SELECTIVA DE CITRAL EN FASE LÍQUIDA SOBRE CATALIZADORES Ir-Fe/TiO 2 REDUCIDOS A ALTA TEMPERATURA SELECTIVE HYDROGENATION OF CITRAL IN LIQUID PHASE OVER Ir-Fe/TiO2 REDUCED AT HIGH TEMPERATURE
The citral hydrogenation was studied over Ir-Fe/TiO2 catalysts reduced at 773 K (HTR: high temperature reduction). The catalysts synthesis was made using H2IrCl6 aqueous solution to get ca. 1% wt Ir load and by impregnating FeCl3 solution to obtain bimetallic catalysts. The results showed that all of the studied Ir/TiO2 and Fe–Ir/TiO2 catalysts display high selectivities (ca. 100%) towards the unsaturated alcohols (geraniol and nerol) during citral hydrogenation.
