Description
Verfahren zur Darstellung von 3. 3'-Dichlor-N-N'-dihydro-1. 2. 21. 1'-anthrachinonazin. Im Hauptpatent wurde die Darstellung des durch Einwirkung oxydierender Mittel auf 2-aminoanthrahydrochinon-9.10-diester- sulfosaure Salze erhältlichen N-N'-Dihydro- 1.2.2'.1'-anthrachinonazins beschrieben.
Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Darstellung des 3.3'-Dichlor- N . N'- dihydro-1 . 2 . 2'. 1'- anthrachinonazins, welches darin besteht, dass man ein 3-chlor- 2-aminoanthrahydrochinon - 9 . 10-diestersulfo- saures Salz von der Formel
EMI0001.0015
in wässeriger Lösung mit Oxydationsmitteln behandelt.
Die als Ausgangsmaterial zur Verwendung gelangenden 3-chlor-2-aminoanthrahydrochi- non-9. 10-diestersulfosauren Salze erhält man nach bekannten Methoden, indem man 3- Chlor-2-acylaminoanthrachinon reduziert, die Hydroxylgruppen mittelst Chlorsulfonsäure verestert und den N-Acylrest abspaltet.
Die Oxydation kann in verschiedenster Weise, in Gegenwart von Säuren oder Al kalien vorgenommen werden, bei gewöhnlicher oder erhöhter Temperatur.
Beispiele: 1. Eine wässerige Lösung von 46,4 Ge wichtsteilen des Dinatriumsalzes der 2-Amino- 3-chloranthrahydrochinon -9 . 10-diestersulfo- säure wird mit 4 Gewichtsteilen Natronlauge von 401 versetzt und unter Rühren bei ge wöhnlicher Temperatur mit einer 2,8 volumen prozentigen Hypochloritlösung versetzt, bis dieses bleibend im Überschuss vorhanden ist.
Nach einiger Zeit nimmt man den Überschuss des Hypochlorits weg, zum Beispiel mit Sulfit, macht dann mit einer organischen Säure, zum Beispiel Ameisensäure, sauer, filtriert den violettblauen Niederschlag ab und wäscht ihn mit kochsalzhaltigem Wasser gut aus. Das Oxydationszwischenprodukt löst sich mit blauer Farbe in heissem Wasser. Zur Über führung in. den Farbstoff versetzt man diese Lösung mit Mineralsäure, zum Beispiel Schwe- felsäiire und lässt in der Wärme Ferrisulfat- lösung im Überschuss hinzugiessen.
Nach ei niger Zeit filtriert man den ausgeschiedenen Farbstoff ab. Er wird gereinigt durch Aus kochen mit Pyridin und eventuell durch Um- küpen und bildet ein violettblaues Pulver, das mit alkalischem Hydrosulfit eine blaue klare Küpe gibt und Baumwolle blau färbt.
2. Eine Lösung von 46,4 Gewichtsteilen des Dinatriumsalzes der 2 -Atnino - 3 - chlor- anthrahydröchinon-9.10-diestersulfosäure in 400 Gewichtsteilen Wasser stellt man in der Kälte mit Salzsäure schwach sauer und lässt sie bei gewöhnlicher Temperatur in eine Lö sung von 120 Gewichtsteilen technischen Ei- senehlorids in 600 Gewichtsteilen Wasser und 50 Gewichtsteilen 10 % iger Salzsäure ein-
laufen. Nach 24 Stunden wird das grünstichig braune Oxydationszwischenprodukt abgesaugt, gewaschen und getrocknet. Zur Überführung dieses Oxydationszwischenproduktes in das N. N'-Dihydro-3. 3'-dichlor-1. 2. 2'. 1'-anthra- chinonazin kocht man es mit hochsiedenden organischen Lösungsmitteln, zum Beispiel mit Nitrobenzol oder a-Chlornaphtalin unter gleich zeitigem Durchleiten von Luft.
Nach dem Absaugen und Auswaschen mit warmem Py- ridin hinterbleibt der Farbstoff als glänzendes violettblaues Pulver, das eventuell durch Um- küpen weiter gereinigt werden kann. Er ist mit dem nach Beispiel 1 erhaltenen identisch.
3. Zu 50 Gewichtsteilen einer 15 % ixen Natriumsulfatlösung, die man auf<B>80-850</B> erhitzt; lässt man unter Rühren gleichzeitig und gleichmässig zulaufen:
einerseits eine Lö. sang von 100 Gewichtsteilen Ferrisulfat und 50 Gewichtsteilen Natriumsulfat in 350 Ge wichtsteilen Wasser und anderseits eine Lö sung von 46,4 Gewichtsteilen Dinatriumsalz der 2-Amino-3-ehloranthrahydrochinon-9. 10- diestersulfosäure -und 8- Gewichtsteilen Ätz natron. Darnach rührt man noch einige Zeit, filtriert und arbeitet den dunkelbraungrünen Rückstand in der in Beispiel 2 beschriebenen Weise auf: Der Farbstoff ist mit jenem iden tisch.
Process for the preparation of 3. 3'-dichloro-N-N'-dihydro-1. 2. 21. 1'-anthraquinonazine. The main patent describes the preparation of the N-N'-dihydro-1.2.2'.1'-anthraquinonazine obtainable by the action of oxidizing agents on 2-aminoanthrahydroquinone-9.10-diester sulfonic acid salts.
The subject of this additional patent is a process for the preparation of 3.3'-dichloro-N. N'-dihydro-1. 2. 2 '. 1'-anthraquinone azines, which consists in the fact that one 3-chloro-2-aminoanthrahydroquinone - 9. 10-diestersulfonic acid salt of the formula
EMI0001.0015
treated in aqueous solution with oxidizing agents.
The 3-chloro-2-aminoanthrahydroquinone-9 used as starting material. 10-diestersulfonic acid salts are obtained by known methods by reducing 3-chloro-2-acylaminoanthraquinone, esterifying the hydroxyl groups using chlorosulfonic acid and splitting off the N-acyl radical.
The oxidation can be carried out in various ways, in the presence of acids or alkalis, at ordinary or elevated temperature.
Examples: 1. An aqueous solution of 46.4 parts by weight of the disodium salt of 2-amino-3-chloroanthrahydroquinone -9. 10-diestersulphonic acid is mixed with 4 parts by weight of 401 sodium hydroxide solution and, while stirring, a 2.8 volume percent hypochlorite solution is added at normal temperature until this remains in excess.
After a while, the excess hypochlorite is removed, for example with sulfite, then made acidic with an organic acid, for example formic acid, the violet-blue precipitate is filtered off and it is washed out well with saline water. The oxidation intermediate dissolves in hot water with a blue color. In order to convert it into the dye, mineral acid, for example sulfuric acid, is added to this solution and excess ferric sulfate solution is poured in while being heated.
After a while, the precipitated dye is filtered off. It is cleaned by boiling it with pyridine and possibly by pouring it over and forms a violet-blue powder which, with alkaline hydrosulphite, gives a clear blue vat and dyes cotton blue.
2. A solution of 46.4 parts by weight of the disodium salt of 2-atnino-3-chloro-anthrahydrochinone-9.10-diestersulfonic acid in 400 parts by weight of water is made weakly acidic in the cold with hydrochloric acid and is left in a solution of 120 at ordinary temperature Parts by weight of technical iron chloride in 600 parts by weight of water and 50 parts by weight of 10% hydrochloric acid
to run. After 24 hours, the greenish brown oxidation intermediate is filtered off with suction, washed and dried. To convert this oxidation intermediate into the N.N'-dihydro-3. 3'-dichloro-1. 2. 2 '. 1'-anthraquinonazine is boiled with high-boiling organic solvents, for example with nitrobenzene or a-chloronaphthalene, while air is passed through at the same time.
After vacuuming and washing with warm pyridine, the dye remains as a shiny violet-blue powder, which can possibly be further cleaned by pouring it over. It is identical to that obtained in Example 1.
3. To 50 parts by weight of a 15% sodium sulfate solution, which is heated to <B> 80-850 </B>; allow to run in at the same time and evenly while stirring:
on the one hand a lo. sang of 100 parts by weight of ferric sulfate and 50 parts by weight of sodium sulfate in 350 parts by weight of water and on the other hand a solution of 46.4 parts by weight of the disodium salt of 2-amino-3-ehloranthrahydroquinone-9. 10- diestersulfonic acid and 8- parts by weight of caustic soda. The mixture is then stirred for some time, filtered and the dark brown-green residue is worked up in the manner described in Example 2: The dye is identical to that table.
