The disadvantages of C ioco6a should be attributed to the formation of pain of the 11th colony of hardly utilizable sewage,
Дл упрощени проведени процесса, а также получени продукта почти с количественным выходом и ВЫСОКО стененью чистоты предложено бромирование проводить в водной среде в присутствии диопергатора, например НФ и органического растворител , не смешивающегос с водой, например хлорбензола .To simplify the process, as well as to obtain a product with almost quantitative yield and a high purity wall, it has been proposed to conduct bromination in an aqueous medium in the presence of a dioper, for example NF and an organic solvent that is not miscible with water, for example chlorobenzene.
Пример I. 5,1 г водной пасты 1-аминоантрахннон-2-карбоновой кислоты (2,55 г в иересчете на сухой продукт), 0,23 мл хлорбензола , 0,003 г диспергатора НФ и 160 мл воды нагревают при температуре 90°С в течениеExample I. 5.1 g of an aqueous paste of 1-aminoanthracnon-2-carboxylic acid (2.55 g relative to the dry product), 0.23 ml of chlorobenzene, 0.003 g of dispersant NF and 160 ml of water are heated at a temperature of 90 ° C in flow
2 час. Массу охлаждают до 20-25°С порц 1ЯМИ в течение 1 -1,5 час, внос т 0,64 мл брома и раЗМешиБают ири 20-25°С в течение 5-7 час. Избыток брома снимают раствором бисульфита, осадок фильтруют, промывают водой и сушат. Получают 3 г (95%) сухого продукта с содержанием 1-амино-4-бромантрахинон-2-карбоновой кислоты 94%; т. пл. 305-307°С (с разложением). По литературным данныл т. пл. 324-235°С.2 hours The mass is cooled to 20–25 ° C with porcelain liter for 1–1.5 h, 0.64 ml of bromine is introduced, and the dilutions are irradiated at 20–25 ° C for 5-7 h. The excess bromine is removed with a solution of bisulfite, the precipitate is filtered, washed with water and dried. Get 3 g (95%) of the dry product with the content of 1-amino-4-bromoanthraquinone-2-carboxylic acid 94%; m.p. 305-307 ° С (with decomposition). According to the literature data t. Pl. 324-235 ° C.
2. Аналогично в присутств П1 толуола вместо хлорбензола получают l-aNiHно-4-бромантрах11ПОН-2-карбонову1о кис.тоту о выходом 95% и содержан 1е основного вещества 93%. 2. Similarly, in the presence of P1 toluene, instead of chlorobenzene, l-aNiH-4-bromo-anthrases 11PON-2-carboxylic acid is obtained in a yield of 95% and contains 1e of the main substance 93%.
