    摘要: The present invention is directed to a process for the manufacture of 6,10,14-trimethylpentadecan-2-one ("C18-ketone") comprising the step of hydrogenating a mixture of (3E,5E,9E)-3,4-dehydrofarnesylacetone and (3Z,5E,9E)-3,4-dehydrofarnesylacetone with hydrogen in the presence of a catalyst, whereby the catalyst is capable of preferentially hydrogenating carbon-carbon double bonds over carbon-oxygen double bonds. Preferably the catalyst comprises a metal selected from the group consisting of palladium, platinum, rhodium, iridium and nickel and mixtures thereof. A process for the preparation of (2E,6E)-farnesal by selective oxidation of (2E,6E)-farnesol and a process for the manufacture of a mixture of (3E,5E,9E)-3,4-dehydrofarnesylacetone and (3Z,5E,9E)-3,4-dehydrofarnesylacetone from (2E,6E)-farnesal is also disclosed.
