Benzaldehyde
Product introduction:
Benzaldehyde, also known as benzoin aldehyde, is an organic compound formed after the hydrogen of benzene is replaced by aldehyde group. Benzaldehyde is the simplest and the most commonly used aromatic aldehyde in industry.
Chemical property:
At room temperature, it is a colorless liquid with a special almond smell. Benzaldehyde is a compound formed by the direct connection of aldehyde group and phenyl group. It was once called bitter almond oil because of its aroma similar to bitter almond. Benzaldehyde widely exists in the plant world, especially in Rosaceae plants. It mainly exists in the stem skin, leaves or seeds of plants in the form of glycosides, such as amygdalin in bitter almond, cherry, laurel leaves and peach kernel. Benzaldehyde naturally exists in bitter almond oil, patchouli oil, hyacinth oil, Ylang Ylang Ylang oil and other essential oils. The compound is also found in nuts and nuts in the form of glycosides (amygdalin) exists. The chemical properties of benzaldehyde are similar to those of fatty aldehydes, but they are also different. Benzaldehyde cannot reduce Fehling reagent; when reducing benzaldehyde with the reagent used to reduce fatty aldehydes, in addition to the main product benzyl alcohol, some tetrasubstituted o-diols and homodiphenylethylene glycol are produced. In the presence of potassium cyanide, two molecules of benzaldehyde pass through the donor and acceptor Hydrogen atoms produce benzoin. Benzaldehyde can also carry out electrophilic substitution reaction on aromatic nucleus, mainly generating meta substitution products. For example, in nitrification, the main product is m-nitrobenzaldehyde. Nowadays, benzaldehyde is mainly prepared from toluene in different ways.
Purpose:
Benzaldehyde is an important raw material in medicine, dye, perfume and resin industry. It can also be used as solvent, plasticizer and low-temperature lubricant. In the flavor industry, it is mainly used for the deployment of food flavors. It is used in flavoring and tobacco flavors. Although widely used as commercial food condiments and industrial solvents, benzyl alcohol is mainly used to synthesize various other compounds from pharmaceuticals to plastic additives. Benzyl alcohol is also an important intermediate product in the production of perfume, perfume and synthetic aniline dyes.
