1-Naphthol Chemical Properties,Usage,Production

Description

Alpha-naphtol, combined with epichlorhydrine and sodium hydroxide to form alpha-naphtyl glycidyl ether, caused sensitization in one of three workers in a chemical plant.

Chemical Properties

Pale grey to brown solid

Uses

Used in the manufacturing of dyes, intermediates, synthetic perfumes.

Definition

ChEBI: A naphthol carrying a hydroxy group at position 1.

Synthesis Reference(s)

Synthetic Communications, 21, p. 379, 1991 DOI: 10.1080/00397919108016759
Journal of the American Chemical Society, 107, p. 493, 1985 DOI: 10.1021/ja00288a037

Hazard

Toxic by ingestion and skin absorption.

Contact allergens

Alpha-naphthol can be used in dye manufacture and is classified as a hair dye. Combined with epichlorhydrin and NaOH to form alpha-naphthyl glycidyl ether, it caused sensitization in one of three workers in a chemical plant.

Safety Profile

Poison by ingestion and intraperitoneal routes. Moderately toxic by skin contact. An experimental teratogen. Experimental reproductive effects. A severe eye and skin irritant. Mutation data reported. Ingestion of large amounts can cause nephritis, vomiting, diarrhea, circulatory collapse, anemia, convulsions, and death. Can cause kidney irritation and injury to cornea and lens of the eye. Combustible when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Sublime 1-naphthol, then crystallise it from aqueous MeOH (charcoal), aqueous 25% or 50% EtOH, *C6H6, cyclohexane, heptane, CCl4 or H2O. Dry it over P2O5 in vacuo. The 4-nitrobenzoate has m 143o (from EtOH). [Shizuka et al. J Am Chem Soc 107 7816 1985, Beilstein 8 H 596, 6 IV 4208.]
