Chemische Eigenschaften
yellow to beige-brown fine crystalline powder. 3 -Hydroxy-2-naphthoic acid [92-70-6], BON acid, C11H8O3, Mr 188.17, mp 222℃, forms pale yellow crystals from aqueous ethanol. Alkaline solutions have a green fluorescence. Aqueous ferric chloride produces a blue color, and warming with CHCl3– NaOH results in a green color. Oxidation with alkaline permanganate gives 2-carboxyphenylglyoxylic acid and then phthalic acid. Dry distillation produces dibenzoxanthone. Bromination gives the 4,7-dibromo derivative; nitration, the 4-nitro derivative; and sulfonation with oleum, the 5,7-disulfonic acid derivative.
Verwenden
3-Hydroxy-2-naphthoic acid is mainly used as intermediate for the production of dyes and pigments. Further uses are as intermediate for insecticides and pharmaceuticals (ECB, 2000).
Hazard
Irritant.
läuterung methode
Crystallise it from water or acetic acid. The S-benzyisothiuronium salt has m 216-217o (from EtOH). It forms many metal complex salts. [Beilstein 10 H 333, 10 III 1084.]
