| titleOfInvention | Method of isolating 1,5-dioxyanthraquinone |
| abstract | METHOD OF EXAMPLE OF 1,5-DIOXIANTHRAHINON from a mixture of dimethoxy- or dioxyanthraquinones by selectively sulphonating the mixture at elevated temperature followed by diluting the reaction mass with water, characterized in that, in order to reduce the duration of the process, increase the yield and improve the quality of the target product, sulfonation is carried out with sulfuric acid concentration of 100-104.5% in the presence of boric acid with a mass ratio of the mixture and boric acid equal to 1: 0.25-0.45. |
