IRONE Chemical Properties,Usage,Production
Description
α-Irone has a characteristic orris and violet-like odor. The commercially prepared product corresponds generally to the α-isomer.
Chemical Properties
α- Irone has a rich, floral and natural character and constitutes an important element in orris and violet compositions as well as being useful when an exotic nuance is required. α-Irone is extremely diffusive, and it gives volume and tenacity to compositions. In combination with α-irisone (1:20, respectively) gives a natural orris effect.
Chemical Properties
Yellowish liquid; Soluble in alcohol. A mixture of three isomers (α-, βand γ-irone).
Occurrence
Reported found in orris root, raspberry and flowers of Pittosporum sp
Uses
Perfumery, violet odor. The α isomer is also used as a flavoring agent.
Definition
ChEBI: A methyl ketone that is alpha-ionone in which a hydrogen at position 5 of the cyclohex-2-en-1-yl ring is substituted by a methyl group.
Preparation
By intramolecular thermal H-ene reaction of an allysilane.
Taste threshold values
Taste characteristics at 10 ppm: woody, fruity, raspberry, orris, and berry with seedy nuances.
General Description
Irone is a bioactive compound that is produced by an endophytic fungus in the rhizomes of Iris germanica.
Synthesis
Alpha-n-Methy lionone is synthesized by condensation of Methylethyl ketone with Citral, and cyclization of the resulting Pseudomethylionone. Cyclization may be carried out with Boron trifluoride or other agent.
Purification Methods
If large amounts are available, then fractionate through a Podbielniak column (p 10) or an efficient spinning band column, but small amounts are distilled using a Kügelrohr apparatus. The 4-phenylsemicarbazone has m 174-175o (165-165.5o).
