purpose
The main uses of phenylacetal-dehyde are concentrated in the spice industry and chemical synthesis fields:
Spice industry: It is an important ingredient for preparing flower scented essence such as hyacinth, narcissus, rose and clove, and is widely used in perfume, cosmetics and food essence. GB 2760-1996 stipulates that it is temporarily allowed to use as food spice, which can be used to prepare essence of bitter almond, strawberry and other foods
Chemical intermediates: As intermediates in various biochemical pathways, they can be used for the synthesis of aldehyde fragrances (reacting with alcohols), phenylacetic acid (oxidation), and phenylethanol (reduction)
Other uses: Can be used as an insect attractant and as a black light trap for pests

synthetic route
The industrial production of phenylacetal-dehyde is mainly achieved through the following two methods:
Phenylethanol oxidation method: Using phenylethanol as raw material, benzal-dehyde is produced through oxidation reaction
β - phenylethanol dehydrogenation method: conversion achieved through dehydrogenation reaction
In addition, it can also be obtained by reducing ethyl phenylacetate
Naturally occurring phenylacetal-dehyde is found in plants such as citrus leaves, roses, and tea leaves
