Use
Citral occurs as (2Z)- and (2E)-isomers (citral a and b, respectively)
analogous to the corresponding alcohols, geraniol and nerol: geranial
(citral a), bp2.7 kPa 118–119 °C, d20 0.8888, n20
D 1.4898; neral (citral b),
bp2.7 kPa 120 °C, d20 0.8869, n20
D 1.4869.
Natural citral is nearly always a mixture of the two isomers. It occurs in lemongrass
oil (up to 85%), in Litsea cubeba oil (up to 75%), and in small amounts inmany
other essential oils. The citrals are colorless to slightly yellowish liquids, with an
odor reminiscent of lemon.
Since citral is an α,β-unsaturated aldehyde with an additional double bond, it
is highly reactive and may undergo reactions such as cyclization and polymerization.
Geraniol, citronellol, and 3,7-dimethyloctan-l-ol can be obtained from citral
by stepwise hydrogenation. Citral can be converted into a number of addition
compounds; the (Z)- and (E)-isomers can be separated via the hydrogen sulfite
addition compounds.The condensation of citral with active methylene groups is
used on an industrial scale in the synthesis of pseudoionones, which are starting
materials for ionones and vitamins.
