| titleOfInvention | Production of anthraquinone-alphasulfonic acids |
| abstract | PRODUCTION OF ANTHRAQUINONE-1-SULFONIC ACID, ANTHRAQUINONE-1,5-DISULFONIC ACID AND ANTHRAQUINONE-1,8-DISULFONIC ACID WHICH ARE SUBSTANTIALLY DEVOID OF MERCURY IN WHICH THE SULFONATION MIXTURE OR THE STRONG SULFURIC ACID SOLUTION IS TREATED AT ELEVATED TEMPERATURE WITH A NONMETALLIC REDUCING AGENT WHOSE REDOX POTENTIAL IS FROM +0.1 TO -0.5 VOLT. AFTER WORKING UP, ANTHRAQUINONE-1SULFONIC ACID, ANTHRAQUINONE-1,5-DISULFONIC ACID AND ANTHRAQUINONE-1,8-DISULFONIC ACID WHOSE MERCURY CONTENT IS 1X10**4% BY WEIGHT AND A FILTRATE HAVING A CONTENT OF LESS THAN 1X10**4% BY WEIGHT OF MERCURY ARE OBTAINED. |
