Abstract: 1,5-DINITROANTHRAQUINONE IS ISOLATED FROM A NITRATION MIXTURE CONTAINING DINITROANTHRAQUINONES BY ALLOWING N-methylpyrrolidone to act on the nitroanthraquinone mixture. From 10 to 45% by weight of the nitroanthraquinone mixture remains undissolved and the undissolved material is separated from the solution. A dinitroanthraquinone is isolated which contains from 75 to 95% by weight of 1,5-dinitroanthraquinone and practically no Beta dinitroanthraquinones.

Abstract translation: 通过允许N-甲基吡咯烷酮作用于硝基蒽醌混合物，从含有四氮杂环戊烷的硝化混合物中分离出1,5-四硝基四氢喹啉。 10至45重量％的硝基蒽醌混合物保持未溶解，并且将未溶解的材料与溶液分离。 分离出二硝基蒽醌，其含有75至95重量％的1,5-二硝基蒽醌，实际上不含β-二硝基蒽醌。
