Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Drug Information
Quinones (ie, 6,12-dione) have been shown to undergo oxidation-reduction cycles involving quinone, hydroquinone, and molecular oxygen, resulting in the formation of oxygen radicals and semiquinone radicals. /Quinones/
Chronic neurotoxic effects include vision disturbances. /From table; Quinones/
Sodium anthraquinone-1-sulfonate Use and Manufacturing
K salt, also called diamant salt, is prepared by sulfonation in the presence of, eg, 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. /Anthraquinone-1-sulfonic acid, potassium salt/|Sodium salt, also called silver salt, is prepared by sulfonation of anthraquinone in the absence of mercury. The acid also can be obtained from the 1,6- (or 1,7-) disulfonic acid by desulfonation at the alpha position in dilute sulfuric acid. /Anthraquinone-2-sulfonic acid, sodium salt/
