1-Naphthol Usage And Synthesis
Chemical PropertiesPale grey to brown solid
UsesUsed in the manufacturing of dyes, intermediates, synthetic perfumes.
DefinitionChEBI: A naphthol carrying a hydroxy group at position 1.
HazardToxic by ingestion and skin absorption.
Contact allergensAlpha-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 ProfilePoison 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 MethodsSublime 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.]
