Versuchsvorschrift

Farnesol (200 g) was dissolved in ethanol (1000 ml), added with platinum oxide (1 g) and stirred for 24 hours at room temperature under hydrogen atmosphere. After the completion of the reaction, insoluble material was removed by filtration through a Celite layer and the filtrate was concentrated under reduced pressure to obtain 3,7,11-trimethyldodecanol (195 g).
