Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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