Description

1 -амино-4-оксиантрахинон-З- сульфокислота  вл етс  ценным полупродуктом дл  получени  полициклических красителей и может быть применена также самосто тельно в качестве красител  дл  ацетатного шелкаи шерсти.1 -amino-4-hydroxyanthraquinone-3-sulfonic acid is a valuable intermediate for polycyclic dyes and can also be used independently as a dye for acetate silk and wool.

Описываемый способ получени  1-амино-4-оксиантрахинон - 3-сульфокислоты  вл етс  более простым и экономичным по сравнению с известным способом ее получени  (например , на основе 1-оксиантрахинона ) за счет использовани  легкодоступного лейкосоединени  1-амино4-оксиантрахинона , получаемого аминированием хинизарина.The described method for the preparation of 1-amino-4-oxyanthraquinone-3-sulfonic acid is simpler and more economical than the known method of its preparation (for example, based on 1-oxyanthraquinone) by using the readily available 1-amino-oxyanthraquinone leuko compound obtained by aminating quinizarin .

Особенность описываемого способа заключаетс  в том, что лейкосоединение 1 -амино-4-аксиантрахинона сульфируют и окисл ют серным ангидридом в сернокислом растворе.The peculiarity of the described method is that the leuconid of 1-amino-4-axianthraquinone is sulphated and oxidized with sulfuric anhydride in sulfuric acid solution.

Пример. 2,41 г лейкосоединенн  1-амино-4-оксиантрахинона смешивают с 24 г моногидрата или слабого олеума, добавл ют в смесь 3,9 г 60-65%-ного олеума, подогревают до температуры 80-90° и выдерживают при этой температуре доExample. 2.41 g of leuco-compound of 1-amino-4-hydroxyanthraquinone is mixed with 24 g of monohydrate or weak oleum, 3.9 g of 60-65% oleum are added to the mixture, heated to a temperature of 80-90 ° and kept at this temperature to

полной растворимости пробы в воде .complete solubility of the sample in water.

После выдержки в реакционнуюмассу добавл ют 10 мл воды при температуре 80-90°, продукт отфильтровывают , отмывают от серной кислоты разбавленной сол ной кислотой и сушат.After soaking, 10 ml of water at a temperature of 80-90 ° is added to the reaction mass, the product is filtered off, washed with sulfuric acid with dilute hydrochloric acid and dried.

Выход продукта составл ет до 87% от теории, счита  на лейкосоединение 1-амино-4-оксиантрахинон.The yield of the product is up to 87% of theory, considering 1-amino-4-hydroxyanthraquinone on the leuco-compound.

Продукт представл ет собой внутреннюю соль сульфокислоты, плохо растворимую в холодной воде и раствор ющуюс  в гор чей воде с розовым окрашиванием, переход ш ,им в синее при добавлении соды. При подкислении раствора избытком минеральной кислоты выдел ет с  светло-желтые кристаллы соли.The product is an internal salt of sulfonic acid, poorly soluble in cold water and dissolving in hot water with a pink coloration, passing w, to blue when soda is added. When the solution is acidified with an excess of mineral acid, light yellow salt crystals are precipitated with it.
