الإجراء التجريبي

100 g of 2,4-Dimethyl-5-phenyl-pentanol (obtained as described in EP 0 908 439) combined with 2 g Ru on aluminium oxide (Ru content: 5 wt. %) were hydrogenated in 80 ml cyclohexane at a hydrogen pressure of 22 bar and at a temperature of 105° C. After 18 hours the reaction was finished. The catalyst was removed and the product distilled. 100 g (content: 99.5%) of 5-cyclohexyl-2,4-dimethyl-pentanol were obtained.
