• Beschreibung

  First produced in 1826 by Otto Unverdorben through destructive distillation of indigo, the first industrial use was as a purple dye, Mauveine, formulated by William Henry Perkin accidentally in an attempt to isolate quinone. The name aniline was given in deference to the indigoyielding plant, Indigofera suffruticosa, commonly named anil.

• Chemische Eigenschaften

  Aniline,C6H5NH2, is slightly soluble in water,miscible in alcohol and ether,and turns yellow to brown in air. Aniline may be made(1) by the reduction, with iron or tin in HCI, of nitrobenzene, and(2) by the amination of chlorobenzene by heating with ammonia to a high temperature corresponding to a pressure of over 200 atmospheres in the presence of a catalyst(a mixture of cuprous chlorideandoxide).Aniline is the end point of reduction of most mononitrogen substituted benzene nuclei,as nitro benzene beta-phenyl hydroxylamine, azoxybenzene, azobenzene, hydrazobenzene. Aniline is detected by the violet coloration produced by a small amountof sodium hypochlorite. Aniline is used as a solvent, in the preparation of compound in the manufacture of dyes and their intermediates, and in the manufacture of medicinal chemicals.

• Physikalische Eigenschaften

  Colorless, oily liquid with a faint ammonia-like odor and burning taste. Gradually becomes yellow to reddish-brown on exposure to air or light. The lower and upper odor thresholds are 2 and 128 ppm, respectively (quoted, Keith and Walters, 1992). An odor threshold of 1.0 ppm_v was reported by Leonardos et al. (1969).

• Verwenden

  Aniline is used in the manufacture of dyes,pharmaceuticals, varnishes, resins, photo graphic chemicals, perfumes, shoe blacks,herbicides, and fungicides. It is also usedin vulcanizing rubber and as a solvent. Itoccurs in coal tar and is produced from thedry distillation of indigo. It is also producedfrom the biodegradation of many pesticides.Aniline is a metabolite of many toxic com pounds, such as nitrobenzene, phenacetin,and phenylhydroxylamine.

• Verwenden

  A thin, colorless oil prepared by reducing benzene with iron filings in the presence of hydrochloric or acetic acid and then separating the aniline formed by distillation. It is slightly soluble in water but dissolves easily in alcohol, ether, and benzene. Aniline is the base for many dyes used to increase the sensitivity of emulsions.

• Verwenden

  Rubber accelerators and antioxidants, dyes and intermediates, photographic chemicals (hydro- quinone), isocyanates for urethane foams, pharma- ceuticals, explosives, petroleum refining, dipheny- lamine, phenolics, herbicides, fungicides.

• Vorbereitung Methode

  Aniline was obtained in 1826 by Unverdorben from distillation of indigo and was given the name aniline in 1841 by Fritzsche (Windholz et al 1983). The chemical was manufactured in the U. S. by the Bechamp reaction involving reduction of nitrobenzene in the presence of either copper/silica or hydrochloric acid/ferrous chloride catalysts; but in 1966, amination of chlorobenzene with ammonia was introduced (IARC 1982; Northcott 1978). Currently, aniline is produced in the U.S., several European countries and Japan by the catalytic hydrogenation of nitrobenzene in either the vapor phase or solvent system. This chemical is also produced by reacting phenol with ammonia (HSDB 1989). Production in 1982 amounted to 331,000 tons (HSDB 1989).

• Hazard

  An allergen. Toxic if absorbed through the skin. Combustible. Skin irritant. Questionable car- cinogen.

• Health Hazard

  Aniline is a moderate skin irritant, a moderate to severe eye irritant, and a skin sensitizer in animals. Aniline is moderately toxic via inhalation and ingestion. Symptoms of exposure (which may be delayed up to 4 hours) include headache, weakness, dizziness, nausea, difficulty breathing, and unconsciousness. Exposure to aniline results in the formation of methemoglobin and can thus interfere with the ability of the blood to transport oxygen. Effects from exposure at levels near the lethal dose include hypoactivity, tremors, convulsions, liver and kidney effects, and cyanosis. Aniline has not been found to be a carcinogen or reproductive toxin in humans. Some tests in rats demonstrate carcinogenic activity. However, other tests in which mice, guinea pigs, and rabbits were treated by various routes of administration gave negative results. Aniline produced developmental toxicity only at maternally toxic dose levels but did not have a selective toxicity for the fetus. It produces genetic damage in animals and in mammalian cell cultures but not in bacterial cell cultures.

• Brandgefahr

  Combustion can produce toxic fumes including nitrogen oxides and carbon monoxide. Aniline vapor forms explosive mixtures with air. Aniline is incompatible with strong oxidizers and strong acids and a number of other materials. Avoid heating. Hazardous polymerization may occur. Polymerizes to a resinous mass.

• Flammability and Explosibility

  Aniline is a combustible liquid (NFPA rating = 2). Smoke from a fire involving aniline may contain toxic nitrogen oxides and aniline vapor. Toxic aniline vapors are given off at high temperatures and form explosive mixtures in air. Carbon dioxide or dry chemical extinguishers should be used to fight aniline fires.

• Chemische Reaktivität

  Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flush with water and rinse with dilute acetic acid; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

• Biochem/physiol Actions

  The acute toxicity of aniline involves its activation in vivo to 4-hydroxyaniline and the formation of adducts with hemoglobin. In erythrocytes, this is associated with the release of iron and the accumulation of methemoglobin and the development of hemolytic anemia and inflammation of the spleen. Tumor formation is often observed in the spleen on prolonged administration.

• Sicherheitsprofil

  Suspected carcinogen with experimental neoplastigenic data. A human poison by an unspecified route. Poison experimentally by most routes incluhng inhalation and ingestion. Experimental reproductive effects. A skin and severe eye irritant, and a rmld sensitizer. In the body, aniline causes formation of methemoglobin, resulting in prolonged anoxemia and depression of the central nervous system; less acute exposure causes hemolysis of the red blood cells, followed by stimulation of the bone marrow. The liver may be affected with resulting jaundice. Long-term exposure to a d n e dye manufacture has been associated with malignant bladder growths. A common air contaminant, A combustible liquid when exposed to heat or flame. To fight fire, use alcohol foam, CO2, dry chemical. It can react vigorously with oxidizing materials. When heated to decomposition it emits highly toxic fumes of NOx. Spontaneously explosive reactions occur with benzenediazonium-2-carboxylate, dibenzoyl peroxide, fluorine nitrate, nitrosyl perchlorate, red fuming nitric acid, peroxodisulfuric acid, and tetranitromethane. Violent reactions with boron trichloride, peroxyformic acid, dhsopropyl peroxydicarbonate, fluorine, trichloronitromethane (145℃), acetic anhydride, chlorosulfonic acid, hexachloromelamine, (HNO3 + N2O4 + H2SO4), (nitrobenzene + glycerin), oleum, (HCHO + HClO4), perchromates, K2O2, ppropiolactone, AgClO4, Na2On, H2SO4, trichloromelamine, acids, peroxydisulfuric acid, F03Cl, diisopropyl peroxy-dicarbonate, n-haloimides, and trichloronitromethane. Ignites on contact with sodium peroxide + water. Forms heator shock-sensitive explosive mixtures with anhnium chloride (detonates at 240°C/7.6 bar), nitromethane, hydrogen peroxide, 1 -chloro-2,3- epoxypropane, and peroxomonosulfuric acid. Reactions with perchloryl fluoride, perchloric acid, and ozone form explosive products.

• Toxikologie

  Aniline, a weakly alkaline liquid, is readily absorbed into the circulation after oral ingestion, inhalation and dermal contact. In human volunteers, more than 90 % of the inhaled aniline vapors (5 – 30 mg/m3) were absorbed in the state of rest . The percutaneous uptake from the vapor phase accounted for 25 – 30 % of the total incorporation in normally dressed individuals at 25 ?C and 35 % relative air humidity (estimated absorption rate: 0.2 – 0.4 μg cm?2h?1), but increased by 21 and 29 % when the temperature was elevated by 5 ?Cand the humidity from 35 to 75 %, respectively . Likewise, when applied as liquid to human skin from a drained gauze (concentration 10 mg/cm2), skin absorption of aniline was between 0.2 and 0.7 mg cm?2h?1 but could reach up to 3.5 mg cm?2h?1 on highly moistened skin , also temperature appeared to be a factor.
  Aniline undergoes rapid oxidation, mainly in the liver, but also in other organs like the intestine and erythrocytes. Three primary transformation reactions compete with each other and are expressed to varying degree in different species and individuals:
  1) N-Hydroxylation
  2) (Ring) hydroxylation
  3) N-Acetylation followed by p-(ring) hydroxylation
  In secondary steps, the hydroxyl intermediates are rapidly conjugated, largely to sulfate and glucuronic acid and excreted, mainly in the urine . In humans, the half-life of aniline is ca. 3.5 h .
  The primary conversion products, mainly phenylhydroxylamine and p-aminophenol as well as their oxidized forms nitrosobenzene and p-iminoquinone, resulting from reactions 1 and 2, are regarded as toxification steps to biologically active compounds (see below), whereas N-acetylation may be considered as a detoxification step, which is followed by phydroxylation to N-acetyl-p-aminophenol. NAcetyl transferase is congenitally expressed to varying extent in humans (“strong and weak acetylators”; see below); this is a reason for different individual susceptibilities.
  Certain metabolites, such as nitrosobenzene, are coupled to thiols, especially glutathione; the quantities of aniline-protein conjugates, especially aniline-Hb adducts in blood, are diagnostic tools for the estimation of aniline exposure and body burden .

• Synthese

  The highly exothermic catalytic hydrogenation (ΔH =?544 kJ/mol at 200 ?C) of nitrobenzene is performed both in the vapor and in the liquid phase in commercially used processes .
  

• mögliche Exposition

  Aniline is widely used as an intermediate in the synthesis of dyestuffs. It is also used in the manufacture of rubber accelerators and antioxidants, pharmaceuticals, marking inks; tetryl, optical whitening agents; photographic developers; resins, varnishes, perfumes, shoe polishes, and many organic chemicals.

• Erste Hilfe

Do not make an unconscious person vomit.Note to physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobinemia in urine.

• Carcinogenicity

  The IARC has classified aniline as a Group 3 carcinogen, that is, not classifiable as to its carcinogenicity. However, NIOSH has determined that there is sufficient evidence to recommend that OSHA require labeling this substance a potential occupational carcinogen. This position followed an evaluation of a high-dose feeding study of aniline hydrochloride in F344 rats and B6C3F1 mice (3000 or 6000 ppm and 6000 or 12,000 ppm, respectively). The test was negative in both sexes of mice; however, hemangiosarcomas of the spleen and combined incidence of fibrosarcomas and sarcomas of the spleen were statistically significant in the male rats; the number of female rats having fibrosarcomas of the spleen was also significant.

• Source

  Detected in distilled water-soluble fractions of regular gasoline (87 octane) and Gasohol at concentrations of 0.55 and 0.20 mg/L, respectively (Potter, 1996). Aniline was also detected in 82% of 65 gasoline (regular and premium) samples (62 from Switzerland, 3 from Boston, MA). At 25 °C, concentrations ranged from 70 to 16,000 μg/L in gasoline and 20 to 3,800 μg/L in watersoluble fractions. Average concentrations were 5.8 mg/L in gasoline and 1.4 mg/L in watersoluble fractions (Schmidt et al., 2002).
  Based on laboratory analysis of 7 coal tar samples, aniline concentrations ranged from ND to 13 ppm (EPRI, 1990).
  Aniline in the environment may originate from the anaerobic biodegradation of nitrobenzene (Razo-Flores et al., 1999).
