use | can be used as dye intermediate. |
production method | in the presence of mercury sulfate, anthraquinone sulfonation at the same time to obtain 1,5-and 1,8-anthraquinone disulfonic acid isomers. Dilute the sulfonate with sulfuric acid, precipitate 1, 5-anthraquinone disulfonic acid first, filter, and separate 1, 5-anthraquinone disulfonic acid. The filtrate and lotion are used to produce anthraquinone -1, 8-disulfonic acid. |
