1-아미노-2-나프톨-4-술폰산 C화학적 특성, 용도, 생산
화학적 성질
1-Amino-2-hydroxynaphthalene-4-sulfonic acid [116-63-2]. (4-amino-3-hydroxynaphthalene-1-sulfonic acid), B€oniger acid, C10H9NO4S, Mr 239.2, is obtained as white or gray needles of the hemihydrate, which is only sparingly soluble in hot water. The alkali-metal salts are soluble in water, but the solutions slowly oxidize in air. Oxidation with nitric acid gives 1,2- naphthoquinone-4-sulfonic acid.용도
1-Amino-2-naphthol-4-sulfonic acid can be used in determination of phosphate.Purification Methods
Purify it by warming 15g of the acid, 150g of NaHSO3 and 5g of Na2SO3(anhydrous) with 1L of water to ca 90o, shaking until most of the solid had dissolved, then filtering hot. The precipitate obtained by adding 10mL of conc HCl to the cooled filtrate is collected, washed with 95% EtOH until the washings are colourless, and is dried under vacuum over CaCl2. It is stored in a dark-coloured bottle, in the cold [Chanley et al. J Am Chem Soc 74 4347 1952]. [Beilstein 14 IV 2825.]1-아미노-2-나프톨-4-술폰산 준비 용품 및 원자재
