Nerol (according to IUPAC ( Z -2,6-dimethyl-2,6-octadien-8-ol) called) is an acyclic monoterpene - alcohol . The clear liquid has a fresh, sweet, rosy-citrus-like odor. Nerol is isomeric to geraniol .

structure

Geraniol is the trans isomer, nerol the cis isomer of the compound with the same empirical formula. It is a primary, monohydric alcohol: the molecule has a hydroxyl group , only one additional carbon atom is directly bonded to the carbon atom to which this hydroxyl group is attached.

Real lavender

Occurrence

Nerol is found in many essential oils such as lavender or rose oil . It always occurs together with geraniol.

Manufacturing

Nerol is a by-product of the production of geraniol and is mainly obtained in this way.

properties

The flash point is 100 ° C. Less than a gram of nerol is soluble in one liter of water . At the air nerol will nerol oxide oxidized . Nerol is harmful to health.

use

It is required for the production of citral , citronellol , vitamin A and vitamin E. Nerol is used as a fragrance in perfumery in rose and flower fragrance compositions.
