Citral Chemical Properties,Uses,Production
Chemical Properties
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.
Occurrence
Reported found in apricot, clary sage, ginger, grape, grapefruit, lemon, lime, mandarin, orange, raspberry, tamarind, tangerine, tea and tomato.
Uses
Citral is an anti-microbial agent found in plants with antibacterial activity against some food pathogens. It is also a fragrance compound with a distinct lemon scent.
Definition
Commercial material is a mixture of α and β isomers.
General Description
A clear yellow colored liquid with a lemon-like odor. Less dense than water and insoluble in water. Toxic by ingestion. Used to make other chemicals.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Citral is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Citral can react with alkalis and strong acids. Citral can readily isomerize.
Hazard
Questionable carcinogen.
Fire Hazard
Citral is combustible.
Contact allergens
Citral is an aldehyde fragrance and flavoring ingredient, a blend of isomers cis (Neral) and trans (geranial). As a fragrance allergen, citral has to be mentioned by name in cosmetics within the EU.
Safety Profile
Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. Experimental reproductive effects. A severe human and experimental skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
