HCID 44192644Cyclohexanepentanol, .beta.-methyl-Ausbeute 99,9 %

Versuchsvorschrift

3415 g of 2-Methyl-5-phenyl-pentanol (Rosaphen™, supplier: Symrise) combined with 33 g Ru on activated carbon (Ru content: 5 wt. %) were hydrogenated at a hydrogen pressure of 20 bar and at a temperature of 100° C. After 14-17 hours the reaction was finished. The catalyst was removed and the product distilled. 3437 g (content: 99.9%) of 5-cyclohexyl-2-methyl-pentanol were obtained. Yield: 97% of theoretical.
