4-AMINOAZOBENZENE Chemical Properties,Usage,Production
Description
This azoic coloring can be reduced in paraphenylenediamine (PPD). It ean be found in some semipermanent hair dyes, and patch tests are frequently positive (about 30%) in hairdressers with hand dermatitis. Because of cross-sensitivity, the detection of sensitization to p-aminoazobenzene may be assumed by a PPD test.
Chemical Properties
4-Aminoazobenzene forms yellow to tan crystals or orange needles.
Chemical Properties
powder
Uses
In form of its salts in dyeing; intermediate in manufacture of Acid Yellow, diazo dyes and indulines.
Uses
as a dye for lacquer, varnish, wax products, oi! stains and styrene res ins; in insecticides; used as an intermediate in the manufacture of Acid Yellow, diazo dyes and indulines.
Preparation
commonly known as Aniline Yellow. (a) aniline?hydrochloride solution added to a aniline?diazonium salt, and slowly, until aniline?diazonium salt salt disappear so far. Then in contain a small amount of aniline?hydrochloride aniline?solution will product (Diazoaminobenzene) 30 ~ 40 ℃ heating 2 ~ 3 hours,??acidified to form 4-(Phenyldiazenyl)benzenamine??hydrochloride and crystalline precipitates. In order to obtain 4-(Phenyldiazenyl)benzenamine?times the company, and then 4-(Phenyldiazenyl)benzenamine hydrochloride dissolved in water and mercerized. (B) aniline?diazotization and coupling anilino-methanesulfonic acid, sodium hydroxide solution and then with boiled together, hydrolyzed mesylate.
Definition
ChEBI: Azobenzene substituted at one of the 4-positions by an amino group.
General Description
Odorless brownish-yellow needles with bluish coating, or an orange powder.
Air & Water Reactions
Dust may form an explosive mixture in air. Insoluble in water.
Reactivity Profile
4-AMINOAZOBENZENE can detonate, particularly if sensitized by the presence of metal salts or strong acids. May form toxic gases with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. May form flammable gases with alkali metals. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides. Emits toxic fumes of oxides of nitrogen when heated to decomposition (over 350°C) [Sax, 2nd ed., 1965, p. 417].
Hazard
Possible carcinogen.
Fire Hazard
Flash point data for 4-AMINOAZOBENZENE are not available; however, 4-AMINOAZOBENZENE is probably combustible.
Contact allergens
This azoic coloring can be reduced in para-phenylenediamine (PPD). It can be found in some semi-permanent hair dyes and patch tests are frequently positive (about 30%) in hairdressers with hand dermatitis. Because of hydrolysis of the azo bond, the detection of sensitization to p-aminoazobenzene may be assumed by a PPD test.
Safety Profile
Confirmed carcinogen with experimental neoplastigenic and tumorigenic data. Poison by intraperitoneal route. An experimental teratogen. Mutation data reported. Used as a dye for lacquer, varnish, wax products, oil stains, and styrene resins. When heated to decomposition it emits toxic fumes of NOx. See also AMINES
Potential Exposure
An azo compound used in form of salts in dyeing; used as intermediate in manufacture of acid yellow and diazo dyes; in insecticides, waxes, lacquers, varnishes, stains, styrene resins

Properties and Applications
green light yellow to red light yellow. Melting point is 127.5 ℃, its hydrochloride for blue crystal. Soluble in ethanol, slightly soluble in water for yellow. In concentrated sulfuric acid for brown, red after diluted solution; In hydrochloric acid solution for red, boil color disappear. Used for alcohol soluble paint, varnish, paraffin wax, oil, synthetic resin coloring.

Purification Methods
Crystallise this dye from EtOH, CCl4, pet ether/*C6H6, or a MeOH/H2O mixture. [Beilstein 16 IV 445.]
Incompatibilities
Dust may form explosive mixture with air. Azo compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This chemicalis sensitive to prolonged exposure to heat. This chemical is incompatible with strong oxidizing agents
