CIM-Shishir (>70%), readily undergoes auto-oxidation leading to the formation of toxic by-products like oxidized linalool. Besides, harmful effects of linalool on humans as well as in the environment have been increasing rapidly. This study highlights the value addition of linalool to a more stable form via catalytic hydrogenation using biochar-supported Ni-Pd and activated charcoal. Under the optimized reaction conditions of 13 bar H2 pressure at 150 °C with a reaction time of 60 min, the designed catalysts hydrogenate linalool (I) to 6,7-dihydrolinalool (II) and tetrahydrolinalool (III) with 82.5% and 91.6% selectivity, respectively. Catalyst characterization has confirmed the role of metal-support interactions towards governing the selectivity. The industrial potential of the present catalytic process in the synthesis of fine fragrance chemicals has been revealed.PMID:41870438 | DOI:10.1039/d6cc00973e
