| | 1-NITROANTHRAQUINONE Usage And Synthesis |
| Chemical Properties | Yellow needles from AcOH;yellow
plates by sublimation; soluble in EtOH and Et2O;
slightly soluble in EtOAc, benzene and CHCl3;
insoluble in water. | | Uses | 1-Nitroanthraquinone is used in the manufacture of various dyes, pharmaceuticals and similar products, either directly or after reduction to l-aminoanthraquinone. | | Synthesis Reference(s) | Tetrahedron Letters, 16, p. 1429, 1975 DOI: 10.1016/S0040-4039(00)72160-5 | | Hazard | Hepatotoxic; moderately toxic; may cause
hepatocellular neoplasms, subcutaneous fibromas,
subcutaneous hemangiosarcomas, and type II pneumocyte proliferation. | | Synthesis | 1-Nitroanthraquinone is prepared by nitration of
anthraquinone in nitric acid (danger of explosion!)
, sulfuric acid , organic
solvents , phosphoric acid , or hydrogen
fluoride .
Purification from organic solvents by addition
of bases, such as amines , alcoholates
, or hydrazine , or from water by
addition of sodium sulfite . 1-Nitroanthraquinone
is crystallized from nitric acid ,
from organic solvents, for example, nitrobenzene
, or from amides . The resulting
1-nitroanthraquinone may be finally purified by
high-temperature distillation , . |
