Patentirt im Deutschen Reiche vom 19. Juni 1900 ab.Patented in the German Empire on June 19, 1900.
Aus dem im Patent 120586 beschriebenen Thioakridon läfst sich leicht durch Behandlung mit Phosphorpentachlorid bezw. Brom und rothem Phosphor das sonst schwer zugängliche Mesochlor- bezw. Mesobromakridin darstellen.From that described in patent 120586 Thioacridone can be easily obtained by treatment with phosphorus pentachloride respectively. Bromine and red phosphorus, the otherwise difficult to access mesochlor or. Represent mesobromacridine.
i. Mesochlorakridin.
500 g Thioakridon werden mit 500 g Phosphorpentachlorid und 250 g Phosphoroxychlorid
vermischt im Oelbade unter Rückflufs langsam auf 120 bis 125° erwärmt. Das Ende der
Reaction ist daran zu erkennen, dafs das entstandene Chlorakridin in grüngelben Nadeln
zu sublimiren beginnt. Hierauf wird das Phospboroxychlorid abdestillirt und der Rückstand
nach dem Erkalten mit 10 bis 20 proc. Salzsäure extrahirt, wobei das Mesochlorakridin
in Lösung geht. Aus dem Filtrat wird das Chlorakridin durch Versetzen mit Ammoniak
unter Kühlung ausgefällt. Zur völligen Reinigung wird es in wenig Alkohol gelöst und die
filtrirte Lösung mit Wasser, dem geringe Mengen Ammoniak beigemischt waren, bis zur
bleibenden Trübung versetzt. Es krystallisirt alsdann das reine Mesochlorakridin aus vom
F. P. i22°. In Gegenwart von Salzsäure geht es in der Wärme leicht in Akridon über. Das
Mesochlorakridin ist bereits in der Literatur beschrieben. Graebe und Lagodzinski erhielten
es aus Akridon und Phosphorpentachlorid (Liebig's Ann. Bd. 276, S. 48). Nach vorliegendem Verfahren wird es in reinerer
Form gewonnen, wodurch sich der höhere Schmelzpunkt erklärt; im Uebrigen sind aber
die Producte identisch.i. Mesochloracridine.
500 g of thioacridone are mixed with 500 g of phosphorus pentachloride and 250 g of phosphorus oxychloride and slowly heated to 120 ° to 125 ° in an oil bath under reflux. The end of the reaction can be recognized by the fact that the chloracridine formed begins to sublime in green-yellow needles. The phosphorus oxychloride is then distilled off and, after cooling, the residue contains 10 to 20 percent. Hydrochloric acid extracted, with the mesochloracridine going into solution. The chloracridine is precipitated from the filtrate by adding ammonia with cooling. For complete purification, it is dissolved in a little alcohol, and the filtered solution is mixed with water, to which small amounts of ammonia have been admixed, until it remains turbid. The pure mesochloracridine then crystallizes from the FP 122 °. In the presence of hydrochloric acid, it easily transforms into akridon in the heat. The mesochloracridine has already been described in the literature. Graebe and Lagodzinski obtained it from akridon and phosphorus pentachloride (Liebig's Ann. Vol. 276, p. 48). According to the present process, it is obtained in a purer form, which explains the higher melting point; but otherwise the products are identical.
2. Mesobromakridin.2. Mesobromacridine.
In das gekühlte Gemisch von 200 g Thioakridon und 40 g rothem Phosphor läfst man allmählich 600 g Brom einlaufen. Nach beendigter Reaction wird etwa 20 Minuten auf ioo° erwärmt und hierauf nach dem Erkalten mit 30 bis 40 proc. Schwefelsäure versetzt. Man läfst nun mindestens 1 bis 1Y2 Stunden stehen, filtrirt alsdann und fällt aus dem Filtrat mit Ammoniak das Mesobromakridin. Diesem ist noch ein zweiter basischer Körper vom F. 25 5 ° beigemengt, der sich aber vom Mesobromakridin durch seine Unlöslichkeit in kaltem Aether trennen läfst. Die völlige Reinigung des Mesobromakridins geschieht durch Umkrystallisirung wie beim Mesochlorakridin. Es schmilzt bei 116 bis 1170.600 g of bromine are gradually run into the cooled mixture of 200 g of thioacridone and 40 g of red phosphorus. After the reaction has ended, the mixture is heated to 100 ° for about 20 minutes and then, after cooling, with 30 to 40 percent. Sulfuric acid added. Referring now to läfst least 1 stand up 1Y 2 hours then filtered, and precipitated from the filtrate with ammonia the Mesobromakridin. A second basic body of 25 ° F. is added to this, but it can be separated from the mesobromacridine by its insolubility in cold ether. The complete purification of the mesobromo acridine occurs by recrystallization, as in the case of mesochloro acridine. It melts at 116 to 117 0 .
Die gemäfs vorliegendem Verfahren darstellbaren Prodpcte sollen zur Farbstoffdarstellung Verwendung finden.The products that can be prepared according to the present method are intended for the preparation of dyes Find use.
