1-Aminonaphthalene Chemical Properties,Uses,Production

Chemical Properties


Chemical Properties

α-Naphthylamine exists as white needle-like crystals which turn red on exposure to air. Has a weak ammonia-like odor.


A reagent used to synthesize various dyes used in the textile industry.

General Description

A crystalline solid or a solid dissolved in a liquid. Insoluble in water and denser than water. Contact may slightly irritate skin, eyes and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals.

Air & Water Reactions

Sensitive to exposure to air and light. Insoluble in water. Napthyl amines can be slowly hydrolyzed, releasing NH3 as a byproduct [N.L. Drake, Org. React. 1, (1942), 105].

Reactivity Profile

1-Aminonaphthalene is incompatible with oxidizing agents. 1-Aminonaphthalene is also incompatible with nitrous acid. 1-Aminonaphthalene reduces warm ammoniacal silver nitrate. .


Toxic, especially if containing the β isomer; a questionable carcinogen.

Health Hazard

Inhalation may cause cyanosis (blue color in lips and under finger nails). Contact with liquid causes local irritation of eyes. Neither ingestion nor contact with skin produces any recognized immediate effects.

Fire Hazard

Special Hazards of Combustion Products: Toxic nitrogen oxides are produced in a fire.

Safety Profile

Confirmed carcinogen with experimental tumorigenic data. Along with p-naphthylamine and benzidine, it has been incriminated as a cause of urinary bladder cancer. Poison by subcutaneous and intraperitoneal routes. Moderately toxic by ingestion. Mutation data reported. Combustible when exposed to heat or flame. Incompatible with nitrous acid. To fight fire, use dry chemical, CO2, mist, spray. When heated to decomposition it emits toxic fumes of NOx.

Potential Exposure

α-Naphthylamine is used as an intermediate in dye production; for manufacturing herbicides and antioxidants; in the manufacture of condensation colors, rubber, and in the synthesis of many chemicals, such as α-naphthol, sodium naphthionate; o-naphthionic acid; Neville and Winther’s acid; sulfonated naphthylamines, α-naphthylthiourea (a rodenticide); and N-phenyl- α-naphthylamine.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.


UN2077 alpha-Naphthylamine, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. PGIII.

Purification Methods

Sublime the amine at 120o in a stream of nitrogen, then crystallise it from pet ether (b 60-80o), or absolute EtOH then diethyl ether. Dry it in vacuo in an Abderhalden pistol. It has also been purified by crystallisation of its hydrochloride (see below) from water, followed by liberation of the free base and distillation; it is finally purified by zone melting. The styphnate has m 181-182o (from EtOH). [Beilstein 12 III 2846, 12 IV 3009.] CARCINOGEN.


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, nitrous acid, organic anhydrides, isocyanates, aldehydes. Oxidizes on contact with air.

Waste Disposal

Controlled incineration whereby oxides of nitrogen are removed from the effluent gas by scrubber, catalyst, or thermal device. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
