APPLICATIONS |
|||
| Geraniol is a monoterpenoid C-10 (branched) alcohol found widely as a chief constituent in essential oils including ilang-ilang oil, palmarosa oil, geranium oil, orange flower oil, lemongrass oil, hops oil, and lavender oil. It is a clear to pale-yellow liquid; boiling point 230 C; insoluble in water; soluble in alcohol, ether and most common organic solvents. It is the major constituent of rose-like odor. It is used in perfumery and flavoring. Nerol is the cis-isomer of geraniol. Geranial and neral are the corresponding aldehydes. Citronellol is the dihydrogeraniol and citronellal is the corresponding aldehyde. Citral is the mixture of geranial (trans-citral, called citral A) and neral (cis--citral, called citral A). Citral is the major constituent of emongrass oil, verbena oil, lemon oil, nikkel oil, lime oil, ginger oil, and other plant essential oils. It is the main source of lemon odor. Neral has a less intense, but sweeter. Citral is also used as a flavor. Citral is used as a raw material in the synthesis ionone which is a perfumery and flavoring component itself and used in the production of retinol. Geraniol is a pheromone of certain species of bees, being secreted by the scent glands of worker bees to signal the location of nectar-bearing flowers and the entrances to their hives. Geraniol also find an application as an insect repellants or deterrants. | |||
