| | Sodium anthraquinone-2-sulfonate Usage And Synthesis |
| Chemical Properties | beige powder | | Flammability and Explosibility | Not classified | | 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.] |
