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.
