What is 1-Anthraquinonesulfonic acid?
The Uses of 1-Anthraquinonesulfonic acid
1-Anthraquinonesulfonic Acid Potassium Salt is a related compound of Anthraquinone(A679245). Anthraquinone is an important precursor for many drugs.
Synthesis
Anthraquinone-1-sulfonic acid, K salt, also called diamant salt, is prepared by sulfonation in the presence of, e.g., 0.5 % mercury in 20 % oleum, an amount of SO3 adequate for the sulfonation of about 60 % of the charge. The reaction is controlled in such a manner that about 50 % of the anthraquinone remains unsulfonated. After mercury is precipitated as the sulfide, the unreacted anthraquinone is precipitated by dilution and is collected by filtration. After washing and drying, it is recirculated as ‘reclaimed quinone‘. Mercury is removed completely from the filtrate, and the anthraquinone-1-sulfonic acid is then precipitated as the potassium salt .
