Procedure

365 g of 5-Phenyl-2-n-propyl-pentanol of Synthesis Example 1.2 were combined with 10 g Ru on activated carbon (Ru content: 5 wt. %) and hydrogenated at a hydrogen pressure of 20 bar and at a temperature of 120° C. After 5-7 hours the reaction was finished. The catalyst was removed and the product distilled. 345 g (content: 98.2%) of 5-cyclohexyl-2-n-propyl-pentanol are obtained. Yield: 90.8% of theoretical.
