HCID 23664630Sodium 2-naphtholate

Procedure

2-hydroxy-3-naphthoic acid can be prepared by reacting 2-naphthol with sodium hydroxide to give sodium 2-naphtholate, reacting the sodium 2-naphtolate with carbon dioxide under an increased pressure, and separating the product by means of acid crystallization. The product may optionally be purified.
