Verbenone refers to the two enantiomers (+) - verbenone and (-) - verbenone.
There are colorless liquids with the empirical formula C 10 H 14 O belonging to the monoterpene - ketones count. Both have a minty odor that increases when heated.

Occurrence and representation
Verbenone occurs in the essential oils of rosemary ( Rosmarinus officinalis ) and the lemon bush (also scent verbena, lemon verbena, Aloysia triphylla ). It is together with the verbenol pheromone of the bark beetle . The attractant Verbenol leads to the "gathering" of the beetles on a tree; Finally, Verbenon drives the bark beetles to other trees that have not yet been infested. The ketone can be artificially made from pinene .
properties
Verbenone is flammable, the flash point is around 85 ° C. The substance is readily soluble in ethanol and other organic solvents, but almost not in water.
use
Verbenone serves as a fragrance and is also used as a remedy for the printer's bark beetle , where it acts as a repellent that repels the beetles.
