Synthesis

Anthraquinone-2-sulfonic acid , Na salt, also called silver salt, Mr 288.3, is prepared by sulfonation in the absence of mercury (e.g., according to the procedure cited in). The acid also can be obtained from the 1,6- (or 1,7-) disulfonic acid by desulfonation at the α position in dilute sulfuric acid .

Purification Methods

It crystallises from H2O or MeOH (charcoal). [Costa and Bookfield J Chem Soc, Faraday Trans 1 82 991 1986, Beilstein 11 IV 671.]
