Application

Phthalamic acid may be used to synthesize anthranilic acid via reaction with sodium hypochlorite.

General description

Phthalamic acid can be synthesized from the reaction between ammonia and phthalic anhydride by a modified Auger′s method. Kinetic studies of the intramolecular carboxylic-group assisted hydrolysis of amide bond of phthalamic acid provided the value of pseudo-first order rate constant (k_obs) as 5.1×10^-5sec^-1 at pH 1.3-1.8 and 35^°C. It undergoes hydrolysis about 105 times faster than benzamide.
