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.
