Description and Uses

Benzoic acid is a colorless, crystalline solid also known as benzenecarboxylic acid. It is the simplest aromatic carboxylic acid, with a carboxyl group (-COOH) bonded directly to the benzene ring. It is found naturally in the benzoin resin of a number of plants.

Calorimetry
Benzoic acid is the most commonly used chemical standard to determine the heat of capacity of a bomb calorimeter.
Feed stock
Benzoic acid is used to make a large number of chemicals, important examples of which are :
Benzoyl chloride, C6H5C(O)Cl, is obtained by treatment of benzoic with thionyl chloride, phosgene or one of the chlorides of phosphorus. C6H5C(O) Cl is an important starting material for several benzoic acid derivates like benzyl benzoate, which is used in artificial flavours and insect repellents.
Food preservative
Benzoic acid and its salts are used as a food preservatives, represented by the E-numbers E210 , E211 , E212 , and E213 . Benzoic acid inhibits the growth of mold, yeast and some bacteria. It is either added directly or created from reactions with its sodium, potassium, or calcium salt. The mechanism starts with the absorption of benzoic acid in to the cell.
Medicinal
Benzoic acid is a constituent of Whitfiel's ointment which is used for the treatment of fungal skin diseases such as tinea, ringworm, and athlete's foot. As the principal component of benzoin resin, benzoic acid is also a major ingredient in both tincture of benzoin and Fria's balsam. Such products have a long history of use as topical antiseptics and inhalant decongestants.
Benzoic acid was used as an expectorant, analgesic, and antiseptic in the early 20th century.
