| | Benzanthrone Usage And Synthesis |
| Chemical Properties | light yellow powder | | Uses | hepatotoxic, P450 suppressant | | Uses | Benzanthrone is reducing agent such as iron. Benzanthrone is an important intermediate for manufacturing vat dyes. | | Uses | Manufacture of dyes. | | Definition | A four-ring system. | | General Description | Yellow needles. | | Reactivity Profile | Benzanthrone is incompatible with nitrobenzene and potassium hydroxide. Benzanthrone is also incompatible with strong oxidizing agents. | | Fire Hazard | Flash point data for Benzanthrone are not available; however, Benzanthrone is probably combustible. | | Synthesis | Benzanthrone is prepared commercially by reacting
anthraquinone with glycerol, sulfuric acid,
and a reducing agent, usually iron. This involves
reduction of anthraquinone to anthrone
(122), which condenses immediately with the
acrolein formed by dehydration of glycerol, and
is finally oxidized by the sulfuric acid , , . An improved process is described
in , . More recently, the use of phosphorus or a phosphorus compound, e.g., sodium
hypophosphite, has been proposed as the reducing
agent . Electrochemical procedures
have been also suggested , . It is possible
to start with anthrone prepared in a separate
step, e.g., by hydrogenation . Benzanthrone
is best purified by sublimation. | | Purification Methods | Crystallise benzanthrone from EtOH or xylene. [Beilstein 7 IV 1819.] |
