실험 절차

2-hydroxynaphthalene-3-carboxylic acid is important as an intermediate for pigments or dyes. Generally, the compound is synthesized by reacting β-naphthol with sodium hydride to give sodium β-naphtholate, reacting the resulting compound with carbon dioxide under pressure to give sodium 2-hydroxynaphthalene-3-carboxylate and then, isolating the desired compound by means of acid precipitation i.e. by adding a mineral acid to the salt.
