Resumen:
Liquid-phase selective synthesis of 1-indanol by the heterogeneous catalytic hydrogenation of1-indanone is reported for the first time. The reaction was carried out at 363 K and 10 bar overSiO2-supported Pt, Co and Cu catalysts, using cyclohexane as solvent. All of the catalysts were prepared by the incipient wetness impregnation method. The highest yield and selectivity to 1-indanol was obtained with Cu/SiO2 that also exhibited high stability, since no deactivation after three consecutive hydrogenation cycles was observed. Pt/SiO2 was active for the hydrogenation of both C = O group and aromatic ring, while Co/SiO2 showed high activity for the hydrogenolysis of the C?OH bond. The characterization by different techniques showed important physicochemical differences among the three catalysts. The experimental data were fitted with LHHW kinetic models by combining stochastic and deterministic methods. The performance of catalysts was explained by combining physicochemical characterization and LHHW modelling.
