| 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 (kobs) as 5.1×10-5sec-1 at pH 1.3-1.8 and 35°C. It undergoes hydrolysis about 105 times faster than benzamide. |
