Use:
Benzaldehyde is an important raw material for the pharmaceutical, dye, fragrance and resin industries, and can also be used as a solvent, plasticizer and low-temperature lubricant. In the flavor industry, it is mainly used to formulate edible flavors, and a small amount is used in daily chemical flavors and tobacco flavors. Although widely used as a commercial food flavoring and industrial solvent, benzyl alcohol's main use is in the synthesis of a variety of other compounds, from pharmaceuticals to plastic additives. Benzyl alcohol is also an important intermediate in the production of perfumes, fragrances and the synthesis of certain aniline dyes. The Chemicalbook synthesis of mandelic acid uses benzaldehyde as the initial reagent: hydrocyanic acid is first reacted with benzaldehyde, and the product mandelonitrile is then hydrolyzed to obtain racemic mandelic acid. Glaciologists LaChepelle and Stillman reported in 1966 that benzaldehyde and heptanal inhibit ice crystallization, thereby preventing the formation of DepthHoar. This treatment prevents avalanches due to unstable snow layers. But the compound destroys vegetation and pollutes water sources, and is not widely used for this purpose.
