Beschreibung
α-Ionone has a characteristic violet-like odor. α-Ionone may be prepared by condensing citral with acetone to form pseudoionone, which is then cyclized by acid-type reagents.
Chemische Eigenschaften
α-Ionone has a warm, woody, berry characteristic violet-like odor. The composition of commercial ionones varies widely in the proportion of α- and β-isomers; the specifications given below refer to the best grade of α- and β-ionones and to a commercial grade that contains both α- and β-ionones.
Chemische Eigenschaften
clear yellow liquid
Verwenden
An aroma compound commonly found in essential oils such as rose oil. It is a degradation products of caratenoids produced by caratenoid cleavage dioxygenases (CCD).
Verwenden
alpha-Ionone, is used in many floral accords. Gives a violet flower nuance to compositions, but is also used in rose, woody, amber, balsamic, and powdery fragrances. It is also used in perfumery, flavoring, and vitamin A (retinol) production for cosmetics and toiletries. beta isomer shows a less floral odor than the alpha. It has good substantivity and is used in all areas of perfumery.
Definition
ChEBI: Alpha-ionone is an ionone, an enone and a methyl ketone.
Allgemeine Beschreibung
α-lonone is a C13 norterpenoid formed from the degradation of carotenoids. It is an important fragrance compound used in perfume industries due to its characteristic fine violet and rose scents. Commercially α-lonone is used in cosmetics, personal care products, detergents, etc. As a flavoring agent, it is widely used in various beverages including wine and tea.
Flammability and Explosibility
Not classified
läuterung methode
Purify α-ionone through a spinning band fractionating column. The semicarbazone has m 157-157.5o (from EtOH) and [] D +433o (c 4,
