Chemical Properties |
Amyl cyclopentenone is a colorless or very pale straw-colored liquid.Insoluble in water.
| Uses |
Amyl cyclopentenone is suggested for use in perfume compositions, primarily in the creation of artificial Jasmin, Jasmin bases, specialties, etc. It can also be used as a floralizer for fragrances other than those of the Jasmin type, mainly in the milder florals, and in a few sharper ones, such as Hyacinth.
| Preparation |
Amyl cyclopentenone is prepared from Decenoic acid by treatment with Phosphoric acid.
