Preparation and properties
It is prepared by nitration of benzoic acid, together with significant amounts of 2-nitrobenzoic acid. With a pKa of 3.47, 3-nitrobenzoic acid is about 10x more acidic than benzoic acidBenzoic acid
Benzoic acid , C7H6O2 , is a colorless crystalline solid and the simplest aromatic carboxylic acid. The name derived from gum benzoin, which was for a long time the only source for benzoic acid. Its salts are used as a food preservative and benzoic acid is an important precursor for the synthesis...
