General Description
Yellowish white crystals with an intensely sweet taste.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
2-Nitrobenzoic acid is incompatible with strong oxidizing agents. Also incompatible with strong bases. May react with cyanides .
Health Hazard
ACUTE/CHRONIC HAZARDS: When 2-Nitrobenzoic acid is heated to decomposition it emits very toxic fumes.
Fire Hazard
Flash point data concerning 2-Nitrobenzoic acid are not available, however, 2-Nitrobenzoic acid is probably combustible.
Purification Methods
Crystallise the acid from *benzene (twice), n-butyl ether (twice), then water (twice). Dry and store it in a vacuum desiccator. [Le Noble & Wheland J Am Chem Soc 80 5397 1958.] It has also been crystallised from EtOH/H2O. The amide has m 176.5o (from H2O). [Beilstein 9 III 1466, 9 IV 1046.]
