Benzoic acid is a flaky or needle-shaped crystal with a smell of benzene or formaldehyde, with the chemical formula C₆H₅COOH. Its melting point is 122.13℃, its boiling point is 249℃, and its relative density is 1.2659 (at 15/4℃). It sublimates rapidly at 100℃, and its vapor has a strong irritant effect. Inhalation can easily cause coughing. It is slightly soluble in water and easily soluble in organic solvents such as ethanol and ether. Benzoic acid is a weak acid and is stronger than fatty acids. Their chemical properties are similar, and they can all form salts, esters, acid halides, amides, acid anhydrides, etc., and are not easily oxidized. The benzene ring of benzoic acid can undergo electrophilic substitution reactions, mainly resulting in ortho-substituted products.
