実験手順

1200 g of 2-Methyl-5-phenyl-pentanol (Rosaphen™, supplier: Symrise) combined with 22 g Pd on activated carbon (Pd content: 5 wt. %) were hydrogenated at a hydrogen pressure of 50 bar and at a temperature of 120° C. After 30 hours the reaction was finished. The catalyst was removed and the product distilled. 1170 g (content: 99.6%) of 5-cyclohexyl-2-methyl-pentanol were obtained.
