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. | [Production Methods]

PLUS®; HOELITE®; MORKIT®; REPELL® | [Pharmacology]
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. | [Toxicology]
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. | [Synthesis]
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. | [storage]
Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with this chemicalyou should be trained on its proper handling and storage.Store in tightly closed containers in a cool, well-ventilatedarea away from oxidizers. Sources of ignition, such as smoking and open flames, are prohibited where this chemical isused, handled, or stored in a manner that could create apotential fire or explosion hazard. | [Purification Methods]
Crystallise anthraquinone from CHCl3 (38mL/g), *benzene, or boiling acetic acid, wash it with a little EtOH and dry it under vacuum over P2O5. [Beilstein 7 IV 2556.] | [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. |
