• Beschreibung

  Anthraquinone is a combustible, light yellowto green crystalline solid. Molecular weight= 208.23;Boiling point= 380℃; Melting/Freezing point= 286℃(sublimes); Flash point= 185℃ (cc). NFPA 704 M HazardIdentification (based on NFPA-704 M Rating System):Health 0, Flammability 1, Reactivity 0. Very slightly solublein water; solubility=,13 mg/L at 22℃.

• Chemische Eigenschaften

  Anthraquinone is a combustible, light yellow to green crystalline solid. Soluble in ethanol, ether and acetone, insoluble in water. It may be prepared by reacting benzene with phthalic anhydride. The compoundis the basis of a range ofdyestuffs.

• Occurrence

  Anthraquinones naturally occur in some plants (eg. aloe, senna, rhubarb, and Cascara buckthorn), fungi, lichens, and insects, where they serve as a basic skeleton for their pigments. Natural anthraquinone derivatives tend to have laxative effects.

• Verwenden

  Anthraquinone is used in paper industry as a catalyst to increase the pulp production yield and to improves the fiber strength through reduction reaction of cellulose to carboxylic acid. It is also used as a precursor for dye formation.

• Definition

  ChEBI: Anthraquinone is an anthraquinone that is anthracene in which positions 9 and 10 have been oxidised to carbonyls. It is a colorless crystalline quinone used in producing dyestuffs such as alizarin.

• synthetische

  Anthraquinone is obtained by oxidation of anthracene using sodium dichromate plus sulfuric acid, and is purified by dissolving in concentrated sulfuric acid at 130 °C and pouring into boiling water, whereupon anthraquinone separates as pure solid, and is recovered by filtration. Further purification may be accomplished by sublimation or crystallization from nitrobenzene, aniline or tetrachloroethane.

• Pharmakologie

  Anthraquinone is a secondary repellent and affects birds by causing post-ingestional distress (40). Sometimes, ingestion of anthraquinone-treated food produces vomiting, but often vomiting does not occur and the bird just sits quietly until the discomfort passes. Unlike methiocarb, anthraquinone doe not affect the bird’s nervous system and does not immobilize affected birds. Presumably, the emetic response is produced through irritation of the gut lining, but the actual mechanism is unclear. It is clear, however, that anthraquinone is not a taste repellent or contact irritant. Birds do not hesitate to eat treated food, and they exhibit no sign that treated food is unpalatable to them. The post-ingestional discomfort that results from eating anthraquinone-treated food produces a conditioned aversion to that food type. Birds need to experience the adverse consequences before learning to avoid the protected food. Thus, it is not reasonable to expect losses to cease immediately upon application of the repellent. There will be some level of loss in the crop as the depredating birds acquire the learned avoidance response.

• Sicherheitsprofil

  Moderately toxic by intraperitoneal route. A mild allergen. Mutation data reported. Combustible when exposed to heat or flame. To fight fire, use water, foam, CO2, water spray or mist, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

• Toxikologie

  Based on present knowledge, anthraquinone, unlike the “emodins” (hydroxyanthraquinone glycosides) from anthraquinone drugs , is biologically completely “inert,” i.e., inactive, presumably as a consequence of its insolubility in water and lipids.
  There is no toxicologic information about anthraquinone. Even in the Toxic Substances List no LD50 is found for anthraquinone. In contrast to benzoquinone, which causes severe local irritation and is included in the list of occupational hazards because of its damaging effect on the cornea, a fine dust of anthraquinone to which emulgators were added had no greater effect on the eyes of rabbits than a talcum suspension, as was shown in a BASF study.
  An MAK value of 10 mg/m3 was recommended ; therefore, anthraquinone dust is considered the same as inert dust.

• Synthese

  Anthraquinone is produced from anthracene, where this is available from coal tar, either by oxidation with chromic acid in 48 % sulfuric acid or by oxidation with air in the vapor phase. The oxidation with chromic acid is competitive, provided that the chromium(III) sulfate lye formed can be processed to tanning agents. Anthracene with purity of '94 % is required for both oxidation processes; crude anthracene from coal tar must be purified by recrystallization.
  About 85 % of world production is based on the oxidation of anthracene. Since the mid- 1970s, anthracene production has fallen continuously, creating a supply shortage. Therefore, the complex naphthalene process is gaining in importance. There is an adequate supply of naphthalene in coal tar. If necessary, additional naphthalene can be isolated from the residual oils of gasoline reforming, a process common in the United States.

• mögliche Exposition

  Anthraquinone is an important starting material for vat dye manufacture. Also used in making organics; and used as a bird repellent in seeds.

• Erste Hilfe

  If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions,including resuscitation mask) if breathing has stopped andCPR if heart action has stopped. Transfer promptly to amedical facility. When this chemical has been swallowed,get medical attention. Give large quantities of water andinduce vomiting. Do not make an unconscious person vomit.

• Lager

• Toxicity evaluation

  Anthraquinone is a stable compound that is virtually insoluble in water. It is not phytotoxic and does not inhibit germination of rice seeds or growth of sprouts. It has very low toxicity to birds and mammals, and it appears to be innocuous to insects as well. There is no known hazard to nontarget species from repellent applications of Flight Control.

• Inkompatibilitäten

  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

• Waste disposal

  Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
