It is the simplest aromatic carboxylic acid. The name is derived from gum benzoin, which was for a long time its only source. Benzoic acid occurs naturally in many plants [9] and serves as an intermediate in the biosynthesis of many secondary metabolites. Salts of benzoic acid are used as food preservatives.
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Some traditional names for common carboxylic acids (such as acetic acid) are in such widespread use that they are retained in IUPAC nomenclature, [7] though systematic names like ethanoic acid are also used. Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph−COOH) and are named as one of its derivatives ...

IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria.It works best in low-pH products, below 4.5, where it exists as benzoic acid.
Benzoyl chloride is produced from benzotrichloride using either water or benzoic acid: [2] C 6 H 5 CCl 3 + H 2 O → C 6 H 5 COCl + 2 HCl C 6 H 5 CCl 3 + C 6 H 5 CO 2 H → 2 C 6 H 5 COCl + HCl. As with other acyl chlorides, it can be generated from the parent acid and standard chlorinating agents such as phosphorus pentachloride, thionyl ...
The first reason is PHBA's tendency to sorb to solid particles, which can be approximated by benzoic acid's high K d value of approximately 19. The pKa of PHBA is 2.7, but it is in an environment of a pH between 6–9. [26] [31] Since the pKa is less than the pH, the carboxylic
