Изобретение относитс к новому способу получени 1-алкиламино- или 1-ариламино- З-метилантрапири-донов, которые вл ютс высокоэффективными люминофорами.This invention relates to a new process for the preparation of 1-alkylamino- or 1-arylamino-3-methylanthanopyridone, which are highly efficient phosphors.
В литературе известен способ получени 1-алкил(арил)аминоантрапиридонов действием на натриевую соль о -сульфоацетиламиноантрахинона водной щелочью с последующей обработкой получаемой натриевой соли 1-атрапиридонсульфокислоты аминами.In the literature, a method is known for producing 1-alkyl (aryl) amino-anthopyridones by exposing the sodium salt of α-sulfoacetylaminoanthraquinone with aqueous alkali, followed by treating the sodium salt with 1-atripyridone sulfonic acid with amines.
По предлагаемому способу дл упрощени технологического процесса получени продуктов и использовани более доступного сырь натриевую соль 1-(М-метил-М-сульфоацетиламино) антрахинона обрабатывают ароматическими , алифатическими или циклоалифатическими аминами в водной среде.According to the proposed method, to simplify the process of obtaining products and using more available raw materials, sodium salt of 1- (M-methyl-M-sulfoacetylamino) anthraquinone is treated with aromatic, aliphatic or cycloaliphatic amines in an aqueous medium.
Процесс проходит в одну стадию и дает хроматографически чистые продукты с высокими выходами.The process takes place in one stage and gives chromatographically pure products with high yields.
Пример, 2г натриевой соли 1- (Ы-гиетил-Н-сульфоацетиламино) антрахинона , 25 мл 15%-ного водного раствора циклогексиламина и 4 г ацетата натри кип т т 20 ч в 400 мл воды и затем фильтруют. Получают 1,6 г .(81,6%) З-метил-1-циклогексиламино- .Example 2 g of sodium salt of 1- (L-hyethyl-N-sulfoacetylamino) anthraquinone, 25 ml of a 15% aqueous solution of cyclohexylamine and 4 g of sodium acetate are boiled for 20 hours in 400 ml of water and then filtered. 1.6 g (81.6%) of 3-methyl-1-cyclohexylamino are obtained.
антрапиридона с т.пл. 170-171 0. Смешанна проба с описанным соединением не дает депрессии температуры плавлени , ИК-спектры также идентичны .anthopyridone with so pl. 170-171 0. A mixed sample with the described compound does not depress the melting point, the IR spectra are also identical.
Пример 2. 2г натриевой соли 1-(М-метил-М-сульфоацетиламино) антрахинона и 5 мл f -метоксипропиламина обрабатывают, как в примере 1.Example 2. 2g of sodium salt of 1- (M-methyl-M-sulfoacetylamino) anthraquinone and 5 ml of f-methoxypropylamine are treated as in example 1.
Получают 1,61 г (88,4%) З-метил-1- (/;(-метоксипропиламино) антрапиридона с т.пл. 138-139С. Смешанна проба с соединением, полученным по известному способу, не дает депрессии температуры плавлени ; ИК-спектры также идентичны.1.61 g (88.4%) of 3-methyl-1- (/; (- methoxypropylamino) anthrapyridone with a mp of 138-139 ° C is obtained. The mixed sample with the compound obtained by a known method does not give a melting point depression; IR spectra are also identical.
Пример 3. 2 г натриевой соли 1-(N-мeтил-N-cyльфoaцeтилaминo) антрахинона и 4 мл н-бутиламина обрабатывают так же, как в примере 1.Example 3. 2 g of sodium salt of 1- (N-methyl-N-methyl-acetylamino) anthraquinone and 4 ml of n-butylamine are treated in the same way as in example 1.
Получают 1,4 г (80,4%) 1-н-бутиламино-3-метил-антрапиридона с т.пл. 116117-С . смешанна проба с описанным соединением не дает депрессии температуры плавлени , ИК-спектры также идентичны.Obtain 1.4 g (80,4%) of 1-n-butylamino-3-methyl-anthrapyridone with so pl. 116117-C. the mixed sample with the described compound does not depress the melting point, the IR spectra are also identical.
Пример 4. 2г натриевой соли 1-(N-мeтил-N-cyльфoaцeтилaминo) антрахинона и 5 мл анилина обрабатывают так же, как в примере 1. Получают 1/25 г (67,9%) 1-анилино-З-метил антрапиридона, с т.пл. 278-279 С. Смешанна проба с соединением, полученным по известно способу, не дает депрессии температуры плавлени , ИК (Спектры также идентичны.Example 4. 2g of sodium salt of 1- (N-methyl-N-methyl-acetylamino) anthraquinone and 5 ml of aniline are treated in the same way as in example 1. Get 1/25 g (67.9%) of 1-anilino-3-methyl anthrapyridone , with so-called 278-279 C. The mixed sample with the compound obtained by the known method does not depress the melting point, IR (The spectra are also identical.
