Verfahren zur Darstellung von Kondensationsprodukten der Anthrachinonreihe. In dem Hauptpatent 412,053 und dem Zusatzpatent ¢23a83 wurden Verfahren zur Darstellung von Kondensationsprodukten der Anthrachinonreihe beschrieben, darin bestehend, daß man Benzanthron oder dessen Substitutionsproduktmit aromatischen Säurechloriden kondensiert. Es wurde nun gefunden, daß eine wesentliche Verbesserung der Ausbeute erzielt wird, wenn man während der Schmelzdauer dem Reaktionsgemisch Luft oder Sauerstoff zuführt.Process for the preparation of condensation products of the anthraquinone series. In the main patent 412,053 and the additional patent [23a83] methods for the representation of condensation products of the anthraquinone series, consisting in that benzanthrone or its substitution product with aromatic acid chlorides condensed. It has now been found that there is a substantial improvement in the yield is achieved if air or oxygen is added to the reaction mixture during the melting period feeds.
Offenbar dient der Sauerstoff dazu, die infolge frei werdenden Wasserstoffes primär gebildeten Reduktionsprodukte des Benzanthrons und seiner Substitutionsprodukte in statu nascendi zu oxydieren und sie vor allem der Benzoylierung zu entziehen. Auf diese Weise werden Nebenreaktionen verhindert und so die Bedingungen zu einem einheitlichen Reaktionsverlauf im Sinne obiger Patente gegeben, was sich vor allem in einer besseren Farbstoffausbeute und einer bequemeren Aufarbeitung ausdrückt. Infolge der wesentlich größeren Reinheit der Schmelze nach dem vorliegenden Verfahren können die wie üblich durch Auskochen mit Wasser und verdünnter Salzsäure gereinigten Rohfarbstoffe unmittelbar mit Hypochlorit oxydiert und nachträglich mit Sprit extrahiert werden. Der in Sprit gelöste Anteil läßt sich erforderlichenfalls durch Erhitzen mit Aluminiumchlorid in den gleichen vorerwähnten Farbstoff überführen und stellt in der Hauptsache wohl das 3-peri-Benzoylbenzanthroti dar. Die mittels Sauerstoffoxydation erzeugte Rohfarbschmelze kann auch nochmals mit Aluminiumchlorid versetzt und erhitzt werden, wodurch sich das in Sprit lösliche Zwischenprodukt vermeiden läßt.Obviously, the oxygen serves the purpose of the hydrogen released as a result primarily formed reduction products of benzanthrone and its substitution products to oxidize in statu nascendi and, above all, to withdraw them from benzoylation. In this way side reactions are prevented and so the conditions become one uniform reaction process within the meaning of the above patents given, which is above all Expresses in a better dye yield and a more convenient work-up. As a result of the much greater purity of the melt according to the present process can be cleaned as usual by boiling with water and dilute hydrochloric acid Raw dyes oxidized immediately with hypochlorite and subsequently extracted with fuel will. If necessary, the fraction dissolved in fuel can be removed by heating with aluminum chloride converted into the same dye mentioned above and provides in the main probably the 3-peri-Benzoylbenzanthroti represents. The means of oxygen oxidation The raw color melt produced can also be mixed with aluminum chloride and heated again which avoids the intermediate which is soluble in fuel.
1. Beispiel einer Sauerstoffschmelze. Zu einem Gemenge von 2,9 Teilen Benzanthron und 29oTeilen Aluminiumchlorid gibt man 1o5 Teile Benzoylchlorid. Die Mischung wird dann während etwa .2,.o Stunden bei einer Temperatur von r2o'gehalten und während dieser Zeit Sauerstoff eingeleitet. Die Reaktionsmasse wird nach Beendigung der Schmelze mit Wasser und Salzsäure ausgekocht, neutral gewaschen und während einiger Stunden mit Hypochloritlösung erhitzt, bis die stumpf gelbbraune Farbe der ausgekochten Rohschmelze in ein leuchtendes Orangegelb übergeht. Nach dem Abfiltrieren und Auswaschen erhält man ein ebenso gefärbtes Pulver, welches sich in konzentrierter Schwefelsäure karminrot mit leuchtend moosgrüner Fluoreszenz löst. Letztere rührt von einem geringen Gehalt an Benzoylbenzanthron her und wirkt beim Färben farbschwächend. Durch Extraktion mit Sprit kann diese Beimengung entfernt werden, und es hinterbleibt ein Pulver"von leuchtend orangegelber Farbe, welches die Eigenschaften des sonst durch Umküpen und Ausblasen gemäß Hauptpatent erhaltenen Farbstoffes besitzt. Wird die Schmelzdauer unter gleichzeitigem Zuleiten von Sauerstoff verlängert, so wird die Farbstoffausbeute auf Kosten der geringeren Beimengung an Benzoylbenzanthron erhöht. Die Ausbeuten betragen je nach der Schmelzdauer etwa 7o bis 8o Prozent der Theorie an reinem Farbstoff. z. Beispiel einer Backschmelze. Zu einem Gemenge von 2g Teilen Benzanthron und igoTeilen Aluminiumchlorid gibt man die etwa vierfache Menge an Benzoylchlorid. Die Mischung wird dann etwa q0 Stunden bei 12o ° gehalten und Sauerstoff während dieser Zeit eingeleitet. Hierauf werden nochmals ioo Teile Aluminiumchlorid zum Schmelzfluß hinzugefügt, die Temperatur auf 18o ° gesteigert und 24 Stunden lang gehalten. Das schließlich resultierende schwarze Pulver wird nach dem Auskochen mit Wasser und Salzsäure mit Hypochloritlösung behandelt, bis der Farbenumschlag nach orangegelb stattgefunden hat. Nach dem Auswaschen hinterbleibt ein orangegelbes Pulver, das sich in konzentrierter Schwefelsäure rein violett löst und auch sonst mit dem in Beispiel i erwähnten Endprodukt identisch ist.1. Example of an oxygen melt. To a mixture of 2.9 parts Benzanthrone and 29o parts of aluminum chloride are added to 105 parts of benzoyl chloride. the Mixture is then held for about .2, .o hours at a temperature of r2o ' and during this time oxygen was introduced. The reaction mass is after completion the melt boiled with water and hydrochloric acid, washed neutral and during heated for a few hours with hypochlorite solution until the dull yellow-brown color of the When the raw melt has been cooked, it turns a bright orange-yellow. After filtering off and washing out gives an equally colored powder, which is more concentrated Sulfuric acid carmine red with bright moss green Fluorescence triggers. The latter is due to a low content of benzoylbenzanthrone and has an effect on Color weakening. This admixture can be removed by extraction with fuel and there remains a powder "of a bright orange-yellow color, which the properties of the otherwise obtained by Umküpen and blowing out according to the main patent Owns dye. Is the melting time with simultaneous supply of oxygen prolonged, the dye yield is increased at the expense of the lower admixture Benzoylbenzanthrone increased. The yields are approximately, depending on the melting time 7o to 8o percent of theory on pure dye. z. Example of a baking melt. To a mixture of 2 g parts of benzanthrone and igo parts of aluminum chloride are added about four times the amount of benzoyl chloride. The mixture is then about q0 hours held at 120 ° and introduced oxygen during this time. Be on it 100 parts of aluminum chloride were again added to the melt flow, the temperature increased to 180 ° and held for 24 hours. The final result black powder is after boiling with water and hydrochloric acid with hypochlorite solution treated until the color has changed to orange-yellow. After washing out What remains is an orange-yellow powder that is pure in concentrated sulfuric acid violet dissolves and otherwise identical to the end product mentioned in example i is.
In gleicher Weise wie in vorstehenden Beispielen können Derivate oder Substitutionsproduktp des Benzanthrons und des Benzoylchlorids Verwendung finden.In the same way as in the preceding examples, derivatives or Find substitution product of benzanthrone and benzoyl chloride use.
