What is Benzoic Acid?
Benzoic acid, white with the formula C6H5CO2H; It is a nearly transparent solid. It is sparingly soluble in water and is the simplest aromatic carboxylic acid. Its name is derived from gum benzoin, which has long been the only source. Benzoic acid occurs naturally in many plants and acts as an intermediate in the biosynthesis of many secondary metabolites. Benzoic acid salts are used as food preservatives. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances. Salts and esters of benzoic acid are known as benzoates.
Commercially, almost all of the benzoic acid is consumed in the production of phenol by oxidative decarboxylation at 300-400 °C.
How is Benzoic Acid produced?
Benzoic acid is produced commercially by partial oxidation of toluene with oxygen. The process is catalyzed by cobalt or manganese naphthenates. Abundant materials are used in production and it proceeds with high efficiency.
The first industrial process involved the reaction of benzotrichloride (trichloromethyl benzene) with calcium hydroxide in water, using iron or iron salts as a catalyst. The resulting calcium benzoate is converted to benzoic acid with hydrochloric acid. The product contains significant amounts of chlorinated benzoic acid derivatives. Therefore, benzoic acid for human consumption was obtained by dry distillation of benzoin gum. Benzoic acid suitable for use as a food preservative is now produced synthetically.

What are the uses (processes) of Benzoic Acid?
- Almost all of the commercially produced benzoic acid is used in the production of phenol and caprolactam.
- Benzoate plasticizers such as glycol-, diethyleneglycol- and triethyleneglycol esters are obtained by cross-esterification of methyl benzoate with the corresponding diol.
- Benzoic acid and its salts are used as a food preservative with E numbers E210, E211, E212 and E213. Benzoic acid inhibits the growth of mold, yeast and some bacteria. It is used in the production of many foods such as carbonated drinks, pickles, jam, fruit juice, ketchup.
- Benzoic acid is a component of Whitfield's ointment used in the treatment of fungal skin diseases such as tinea, ringworm and athlete's foot.
- Benzoic acid was used as an expectorant, analgesic, and antiseptic in the early 20th century.
- Laboratory research and recent theoretical studies have highlighted that benzoic acid derivatives are promising for inhibiting coronavirus.
- In chemistry labs, benzoic acid is a common standard reference for calibrating a bomb calorimeter.
- Benzoic acid is used as a component in the content of many personal care products such as shampoo, shaving foam and hair care products.
- There are chemicals created to be added to the coolant section in the antifreezes of the vehicles.
- Insecticides contain benzoic acid.
