    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。

    Abstract: Production of pure 1-nitroanthraquinone from nitroanthraquinone mixtures by treating the mixture in an organic aprotic solvent with a primary or secondary amine or a mixture of the same. A pure 1-nitroanthraquinone in which practically no dinitroanthraquinone or other byproducts can be detected is obtained in a high yield. The 1-aminoanthraquinone obtained from this 1-nitroanthraquinone is suitable for all dye syntheses.

    Abstract: A process for the recovery of 1-nitroanthraquinone in a purified state from a nitroanthraquinone mixture containing it by treatment with a base in the presence of an initiator such as nitrite, halide, thiocyanate, alcoholate or phenolate ions in an organic solvent. A 1-nitroanthraquinone is obtained which is essentially pure or contains only small quantities of isomers and dinitroanthraquinones.

    Abstract: A method of preparing aromatic ketones by reaction of aromatic compounds with acyl chlorides or acyl anhydrides in the presence of catalytic amounts of an aromatic polynitrosulfonic acid, and new aromatic ketones derived from an aromatic compound (as the acylatable compound) having at least two nuclear substituents, at least one of said substituents being a nitro group. Both the known and the new aromatic ketones obtainable are valuable intermediates for the production of dyes and pesticides.
