Abstract
Заявлен способ получения калиевой соли кислого дисернокислого эфира лейкосоединения 3-хлор-2-ацетиламиноантрахинона с использованием восстановления и этерификации при температуре 50-55°C 3-хлор-2-ацетиламиноантрахинонэ железом и пиридиний ангидро-N-сульфокислотой, полученной взаимодействием пиридина с хлорсульфоновой кислотой в среде пиридиновых соединений с последующей обработкой полученной пиридиновой соли кислого дисернокислого эфира лейкосоединения 3-хлор-2-ацетиламиноантрахинона раствором соды, отгонкой пиридиновых соединений, экстракцией и выделением целевого продукта путем обработки хлористым калием. 2-аминоантрахинон подвергают хлорированию хлористым сульфурилом в среде хлорбензола в присутствии пиридина при нагревании. Полученную реакционную массу, содержащую 1,3-дихлор-2-аминоант-рахинон, подвергают обработке уксусной кислотой в среде пиридина в присутствии хлористого тионила с получением 1,3-дихлор-2-ацетиламиноантрахинонэ.The claimed method for producing the potassium salt of acid disulfuric acid ester of the leuco compound 3-chloro-2-acetylaminoanthraquinone using reduction and esterification at a temperature of 50-55 ° C of 3-chloro-2-acetylaminoanthraquinone with iron and pyridinium anhydro-N-sulfonic acid obtained by the reaction of pyridonic acid with chlorosulfonic acid in the medium of pyridine compounds, followed by treatment of the obtained pyridine salt of acid disulfuric ester of the leuco compound 3-chloro-2-acetylaminoanthraquinone with a solution of soda, distillation of pyridine compounds, extraction and isolation of the target product by treatment with potassium chloride. 2-aminoanthraquinone is subjected to chlorination with sulfuryl chloride in chlorobenzene in the presence of pyridine with heating. The resulting reaction mixture containing 1,3-dichloro-2-aminoanthraquinone is subjected to treatment with acetic acid in pyridine in the presence of thionyl chloride to obtain 1,3-dichloro-2-acetylaminoanthraquinone.
