화학적 성질
2-Hydroxynaphthalene-1-sulfonic acid [567-47-5]. oxy Tobias acid, C10H8O4S, Mr 224.2, and its salts are very soluble in water; neutral solutions give a strong blue color with iron(III) chloride. The sulfonic acid group is sufficiently labile for desulfonation to take place slowly in aqueous solution and rapidly with diazo compounds to form 1-azo-2-hydroxynaphthalene derivatives (i.e., the same product as from 2-naphthol), and with bromine to form 1-bromo2-hydroxynaphthalene. Low-temperature sulfonation gives 2-hydroxynaphthalene-1,6-disulfonic acid, whereas higher temperatures result in 1- desulfonation and formation of 2-hydroxynaphthalene-6- and 8-sulfonic acids. Nitration affords 1,6-dinitro-2-hydroxynaphthalene.
