Description

размешивании нагревают 4 ч при . По окончании реакции автоклав охлаждают , вскрывают, неренос т содержимое в колбу, отгон ют аммиак, подкисл ют до слабокислой реакции по бумаге Конго. Выпавший осадок отфильтровывают, промывают водой до нейтральной реакции, сушат . Вес продукта 2,55 г, содержание 1,4диаминоантр1ахинон-2-карбоновой кислоты 98%, выход 100%.stirring heated for 4 h at. At the end of the reaction, the autoclave is cooled, opened, the contents are not transferred to the flask, ammonia is distilled off, acidified to a slightly acidic reaction on Congo paper. The precipitation is filtered off, washed with water until neutral, dried. Product weight 2.55 g, the content of 1,4-diaminoate 1quinone-2-carboxylic acid 98%, yield 100%.

Пример 2. Процесс осуществл ют по примеру 1, но при 120° С и продолжительности реакции 1,5 ч. Вес продукта 2,49 г, сод-ержание 1,4-диаминоантрахинон2-карбоновой кислоты 100%. Выход 100%.Example 2. The process is carried out as in Example 1, but at 120 ° C and a reaction time of 1.5 hours. The weight of the product is 2.49 g, the content of 1,4-diaminoanthraquinone-2-carboxylic acid is 100%. The yield is 100%.
