Abstract
Inventia se refera la un procedeu de obtinere a 8-amino-2-naftolului, utilizat la fabricarea intermediarului N-(7-hidroxi-1-naftil) acetamica, aceasta din urma stand la baza a numerosi coloranti acizi complecsi prin adaugarea 8-amino-2-naftalinsulfonatului de sodiu, sub forma de pasta, într-o topitura de hidroxid de potasiu dupa ce aceasta s-a încalzit la peste 230 grade C.
