Benzaldehyde: An Introduction with Applications

Benzaldehyde, also known as benzenecarboxy aldehyde or benzoic aldehyde, is the most simple, and also the most commonly used industrial aromatic aldehyde. Benzaldehyde is a colorless liquid at room temperature and has a pleasant odor.


Benzaldehyde

 

Benzaldehyde is miscible in volatile oils, fixed oils, ether, and alcohol; it is spar- ingly soluble in water. It is obtained by chemical synthesis and by natural occurrence in oils of bitter almond, peach, and apricot kernel.

 

Benzaldehyde is prepared by hydrolysis of benzal chloride, for example, in acidic media in the presence of a catalyst such as ferric chloride or in alkaline media with aqueous sodium carbonate. Part of the commercially available benzaldehyde originates from a technical process for phenol. In this process, benzaldehyde is a by-product in the oxidation, in air, of toluene to benzoic acid.

 

Benzaldehyde is commercially available in two grades: pure benzaldehyde and double-distilled benzaldehyde. The latter has wide applications in the pharmaceutical, perfume, and flavor industries. Benzaldehyde may contain trace amounts of chlorine, water, benzoic acid, benzyl chloride, benzyl alcohol, and/or nitrobenzene.

 

Benzaldehyde is a component to many popular flavors and fragrances, and it is also vital in the creation of many new custom flavors and fragrances. Benzaldehyde can be used as a flavor enhancer for alcoholic beverages such as beer and other types of liquors, as well as in non-alcoholic products such as soft drinks. It can also be used to provide almond or cherry fragrance in a range of different products.

 

Benzaldehyde is widely used in the synthesis of numerous aromatic chemicals. The increasing application of its derivatives, like sodium benzoate, benzoic acid, benzyl alcohol, and cinnamic acid is expected to drive the benzaldehyde market. These products have wide applications in agrochemicals, pharmaceuticals, paints, inks, lacquers, waxes, dyes, food and beverages, and coatings. Besides, benzoic acid is used as a precursor for the industrial synthesis of organic substances.
