3-Nitrobenzaldehyde, also known as benzoin aldehyde, is an aldehyde group that replaces the simplest organic compound formed after the hydrogen of benzene. It is also the most commonly used aromatic aldehyde in industry. He is a compound formed by the direct connection of an aldehyde group with a phenyl group. He is widely present in the plant kingdom, especially in the Rosaceae, mainly in glycosides in the bark, leaves, or seeds of plants, such as bitter almonds. Amygdalin, cherries, bay leaves, peach pits.
The chemical properties of which are similar to those of fatty aldehydes, but there are differences. He can't reduce Fehling's reagent, but he can also carry out electrophilic substitution reaction on the aromatic nucleus, mainly generating meta-substitution products; for example, the main product during nitration is 3-Nitrobenzaldehyde. Today his main Chemicalbook is prepared from toluene by different routes. How to identify him? It can be determined by appearance and properties: pure products are colorless liquids, industrial products are colorless to light yellow liquids, and with the smell of bitter almonds, at this step, it can be concluded that it is slightly soluble in water, Miscible in ethanol, ether, benzene, chloroform.
It is an important raw material in the pharmaceutical, paint, fragrance, and resin industries and can also be used as a solvent, plasticizer, and low-temperature lubricant. It is primarily used in edible flavor formulations and small quantities in everyday chemical and tobacco flavors in the flavor industry. Widely used as commercial food flavors and industrial solvents, benzyl alcohol's primary use is synthesizing various other compounds, from pharmaceuticals to plastic additives. He is also an essential intermediate in producing perfumes and fragrances and synthesizing certain aniline dyes. Glaciologists LaChapelle and Stillman reported in 1966 that 3-Nitrobenzaldehyde and heptanal inhibit ice crystallization and thus prevent the formation of DepthHoar. This treatment prevents avalanches due to unstable snow layers.
