일반 설명

2-Naphthol (2OH) is a hydroxyarene molecule, which when electronically excited forms strong acid. Excited 2OH dissociates only in water. It has a slight phenolic odor. It is incompatible with strong oxidizing agents, strong bases, acid chlorides and acid anhydrides. It is one of the most commonly used fluorescence dye.

위험도

See α-naphthol

건강위험

Although the toxicity of 2-naphthol is of low order in test animals, ingestion of large amounts may result in nausea, vomiting, diarrhea, abdominal pain, convulsions, and hemolytic anemia. Death may result from respiratory failure. The oral LD50 value in rats is in the range 2000 mg/kg. 2-Naphthol is slightly more toxic than 1-naphthol [9015-3], the oral LD50 value of which is in the range 2500 mg/kg.
Skin contact can produce peeling of the skin and pigmentation.

화재위험

Noncombustible solid.

Safety Profile

Poison by ingestion, inhalation, and subcutaneous routes. Mutation data reported. A skin and eye irritant. Combustible when exposed to heat or flame. To fight fire, use CO2, dry chemical. Incompatible with antipyrine, camphor, phenol, ferric salts, menthol, potassium permanganate and other oxidzing materials, urethane.

잠재적 노출

A potential danger to those involved in rubber antioxidant production, synthesis of dyes; leather processing; fungicides, pharmaceuticals, and perfumes. Used as an antioxidant for fats, oils; as an antiseptic; in insecticides.

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Properties and Applications

white crystalline, with phenol smell. Industrial goods for hoar chip or powder. Melting point 121 ~ 123 ℃, 285 ℃ ~ 286 boiling point, flash point 161 ℃. This product soluble in water, ethanol, ethyl ether, chloroform, glycerin and alkali solution, can the sublimation, with steam evaporate out; Long storage or light color in turn dark, can happen oxidation, reduction, nitrification and nitrosation reaction, and products, light and heat, halogenating role, etc.

Purification Methods

Crystallise 2-naphthol from aqueous 25% EtOH (charcoal), H2O, *benzene, toluene or CCl4. Alternatively, extract it repeatedly with small amounts of EtOH, followed by dissolution in a minimum volume of EtOH and precipitation with distilled water, then drying over P2O5 under vacuum. It has also been dissolved in aqueous NaOH and precipitated by adding acid (repeat several times), then precipitated from *benzene by addition of heptane. Final purification can be by zone melting or sublimation in vacuo. The 4-nitrobenzoate has m 104o (from EtOH). [Bardez et al. J Phys Chem 89 5031 1985, Kikuchi et al. J Phys Chem 91 574 1987, Beilstein 6 IV 4253.]

비 호환성

Dust or powder may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, iron salts; 2,3-dimethyl-1- phenyl-3-pyrazolin-5-one (antipyrine); camphor, phenol, menthol, urethane.

폐기물 처리

Mix with flammable solvent and atomize into an incinerator.
