Benzoic acid is an organic acid that occurs naturally in many plants and fruits, and it is produced industrially because it plays an important role in many sectors.
The areas of use of benzoic acid are quite broad. It is frequently used as a preservative in the food industry and can be found in many food products such as beverages, canned fruit juices, tomato paste, and pickles. It is also used in the pharmaceutical, cosmetics, and textile industries. Its ability to prevent microbes and fungi and extend product shelf life makes this compound valuable from an industrial perspective.
What Is Benzoic Acid?
What Is the Formula of Benzoic Acid and What Are Its Other Names?
The chemical formula of benzoic acid is C6H5COOH. Other names of this compound include phenyl carboxylic acid, benzyl carboxylic acid, and benzene carboxylic acid.
How Is Benzoic Acid Produced?
Industrially, benzoic acid is generally produced from various sources such as toluene or benzyl chloride. It can be obtained from toluene through oxidation or as a result of the reaction of benzyl chloride with hydrogen peroxide. The quality of the raw materials used in these production processes is one of the important factors determining the quality and properties of benzoic acid.
The stages of the production process from aromatic hydrocarbons such as phenol or toluene for the industrial production of benzoic acid are:
- Oxidation from Toluene: Toluene is generally used as the main source of benzoic acid. The methyl group in toluene reacts with an oxygen atmosphere or oxidation agents such as nitric acid. This oxidation reaction converts toluene into benzoic acid.
- Catalytic Oxidation: In some production processes, oxidation of toluene can be carried out catalytically. In this case, special catalysts are used to increase the reaction rate and obtain benzoic acid.
- Hydrogenation and Oxidation: In this step, hydrogenation and oxidation stages may be carried out to remove substances such as benzaldehyde and benzyl chloride, which are by-products of benzoic acid. This process helps obtain benzoic acid of the desired purity.
- Recrystallization: To increase the purity of the obtained benzoic acid, a recrystallization step is applied. In this step, the benzoic acid is dissolved in a suitable solvent and then slowly precipitated.
- Acidification: After recrystallization, the benzoic acid solution is subjected to an acidification step. In this step, an acid is added to the solution, which causes the benzoic acid to precipitate.
- Filtration and Drying: The precipitated benzoic acid is filtered and then dried. This stage ensures that the product is obtained in solid form.
- Packaging and Distribution: Finally, the obtained benzoic acid is packaged and distributed properly to be supplied to industrial customers.
