ANTHRARUFIN - Uses and synthesis methods
use
1,1, 5-dihydroxyanthraquinone is an intermediate of disperse dyes and acid dyes. 1,5-dihydroxyanthraquinone -2,6-disulfonic acid can be obtained from the sulfonation of 1,5-dihydroxyanthraquinone. Continue to nitrification, reduction, addition translocation, and desulphurization of this intermediate to obtain dispersion Blue S-BGL.
2, for synthetic dyes
production method
There are anthraquinone sulfonation and benzoic acid sulfonation. (1) 1,5-anthraquinone disulfonic acid and 1,8-anthraquinone disulfonic acid were obtained by sulfonation with anthraquinone as raw material and mercury sulfate as positioning agent. 1, 5-anthraquinone disulfonic acid by alkali fusion, acidification to obtain 1, 5-dihydroxyanthraquinone. (2) Benzoic acid is used as raw material, obtained by sulfonation, alkali melting, acidification, condensation and closed loop. This method does not use mercury catalyst to remove mercury damage, but the closed-loop one-step yield is only 40%, and a large amount of aluminum trichloride is consumed. This method consumes higher, also brings other aspects of pollution, and high production costs.
