Use
Phenylacetaldehyde has been identified in
many essential oils and as a volatile constituent of foods. It is a colorless liquidwith
a sweet, green odor, reminiscent of hyacinth. Since it readily undergoes oxidation
and polymerizes, it must be stabilized by addition of antioxidants and by dilution
with, for example, diethyl phthalate before use in compositions.
Phenylacetaldehyde can be obtained in high yield by vapor-phase isomerization
of styrene oxide, for example, with alkali-treated silica–alumina. Another
process starts from phenylethane-l,2-diol, which can be converted into phenylacetaldehyde
in high yield. The reaction is performed in the vapor phase in the
presence of an acidic silica–alumina catalyst.
Phenylacetaldehyde is used in perfume compositions, in particular for hyacinth
and rose notes.
