Benzaldehyde is an organic compound, which is the simplest aldehyde belonging to the aromatic series. It is soluble in ether, alcohol, ester and fatty oils as well as in other organic solvents. It reacts with hydrocyanic acid, sodium hydrosulfite and other nucleophilic reagents.
This colorless liquid has a characteristic smell of apple pips or bitter almonds. When stored, it turns yellow and oxidizes to benzoyl peroxide with air oxygen, subsequently converting to benzoic acid.
Benzaldehyde derivatives are present in some plants. They are found in the leaves of bird cherry, bitter almond, common oyster mushroom pulp, seeds, leaves and stems of apple, peach and cherry trees. Benzaldehyde derivatives can also be found in canang, hyacinth and patchouli.
It is the simplest, most commonly used aromatic aldehyde for industrial purposes. It is currently used as follows:
- As a solvent;
- as a food flavoring;
- as part of perfume and cosmetic compositions;
- for synthesis of fragrant substances and dyes;
- for obtaining some medicines.
The main industrial importance of benzaldehyde consists in obtaining from it such compounds as almond, cinnamic, benzyl acid, etc.
