• Chemische Eigenschaften

  Geranylacetone occurs in (5Z)-trans as well as in (5E)-trans form and has been identified in fruits and in essential oils. It is a colorless liquid with a fresh, green, slightly penetrating, rose-like odor.
  Geranylacetone is an intermediate in the synthesis of other fragrance substances. It is mainly produced from linalool. Another route starts from myrcene, to which methyl acetoacetate is added under rhodium catalysis; geranylacetone is subsequently obtained after saponification and decarboxylation. It is used in perfumery in rose compositions, for example, in soap perfumes.

• Chemische Eigenschaften

  6,10-Dimethyl-5,9-undecadien-2-one has a green and rosy floral odor and fresh-floral, light, but rather penetrating sweet-rosy, slightly green, magnolia-like odor. It blends well in lavender and fruity notes, where it imparts a clean and natural character. It helps to round out floral bouquets

  By reaction of linalool and ethyl acetoacetate with an alkaline catalyst and subsequent rearrangement and decarboxylation.

• Definition

  ChEBI: Geranyl acetone is a monoterpene ketone in which an (E)-geranyl group is bonded to one of the alpha-methyls of acetone. It is a component of essential oils from various plants including Nelumbo nucifera. It has a role as a flavouring agent, a fragrance, a volatile oil component and a plant metabolite. It contains a geranyl group.

• Application

  Geranylacetone is an intermediate in nerolidol synthesis. It is used in perfumery in rose compositions, for example, in soap perfumes.
