alizarine synthesis
Does anyone have a synthesis of alizarine from anthraquinone?
In my book is reported that alizarin can be produced oxidising anthraquinone with sodium chlorate and sodium hydroxide, with some water, at 200°C.
Is it possible, and how much time does this reaction require?
Thanks

Sorry, I'm not sure about the actual procedure, but I did find some historical links related to it.
"Carl Theodore Liebermann (1842 -1914) distilled alizarin with zinc dust to give anthracene in 1868, subsequently synthesizing alizarin from
anthraquinone in 1869.
The principal synthesis entailed oxidation of anthraquinone-2-sulfonic acid with sodium nitrate in concentrated sodium hydroxide."
