| alpha-Ionone Usage And Synthesis |
| Description | The alpha-ionone is the alpha form of ionone. The ionones denote a series of chemical substances belonging to rose ketones including carotene, damascenes and damascenones. It is found in various kinds of essential oils contained in some flowers such as violet. Ionone has three forms including alpha-, beta and gamma-. The alpha-ionone has the aroma odor of violet, which has been widely used in daily chemical flavor and tobacco-used flavor. The alpha-ionone can be made from the thermal decomposition of carotene. |

| Description | 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. |
| Chemical Properties | 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. |
| Chemical Properties | clear yellow liquid |
| Uses | 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). |
| Purification Methods | Purify α-ionone through a spinning band fractionating column. The semicarbazone has m 157-157.5o (from EtOH) and [] D +433o (c 4, |
