実験手順

Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)" at monograph 1378 discloses "Farnesal", 2,6,10-trimethyl-2,6,10-dodecatrien-12-al to have a very mild, sweet oily, slightly woody, tenacious odor. On the other hand, Arctander also describes, at Monograph 1379, Farnesene, 2,6,10-trimethyl-2,6,9,11-dodecatetraene defined according to the structure: ##STR3## to have a very mild, sweet and warm, rather nondescript odor of good tenacity. Arctander further states that apart from some possible use in the reconstruction of certain essential oils, there is to the author's knowledge, very little, if any, use for this sesquiterpene in perfumery as such. Arctander further states that Farnesene having the structure: ##STR4## is produced by dehydration of Farnesol by heat with a potassium dehydrating agent or from Nerolidol by heat with acetic anhydride.
