Answer:
The compound 1-naphthol, or α-naphthol, made by heating 1-naphthalenesulfonic acid with caustic alkali or by heating 1-naphthylamine with water under pressure, is used directly in making several dyes, and large amounts of it are converted to compounds ultimately incorporated into other dyes.
