KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. In der Patentschrift Nr. 75490 ist ein Verfahren beschrieben, nach welchem man durch Kochen der Diamidoanthrachrysondisulfosäure mit Alkalien auf einem glatten Wege zur Hexaoxyanthrachinondisulfosäure gelangt. Ebenso leicht wie in der Disulfosöure des Diamidoanthrachrysons lassen sich im letzteren selbst unter Anwendung desselben Verfahrens die Amidogruppen durch Hydroxyl austauschen. Man erhält auf diese Weise dasselbe Hexaoxyanthrachinon wie durch Abspalten der Sulfogruppen aus der in der Patentschrift Nr. 75490 beschriebenen Hexaoxyanthrachinondisulfosäure, welches auch identisch ist mit dem in den Patentschriften Nr. 64418, 65375 und 66153 erwähnten, aus Alizarin oder Alizarinbordeaux oder Anthrachryson auf anderem Wege dargestellten Hexaoxyanthrachinon. In the patent specification No. 75490 a method is described, according to which one by Cooking the diamidoanthrachrysone disulfonic acid with alkalis in a smooth way Hexaoxyanthraquinone disulfonic acid arrives. Just as easily as in the disulfonic acid of diamido anthrachryson In the latter, the amido groups can be exchanged for hydroxyl using the same procedure. In this way, the same hexaoxyanthraquinone is obtained as by splitting off the sulfo groups from that in the patent No. 75490 described hexaoxyanthraquinone disulfonic acid, which is also identical to that mentioned in Patent Nos. 64418, 65375 and 66153, from alizarin or Alizarinbordeaux or anthrachryson represented in another way Hexaoxyanthraquinone. Das Diamidoanthrachryson, welches in der Patentschrift Nr. 81741 beschrieben ist, erhält man durch Reduction des nach Patentschrift Nr. 71964 dargestellten Dinitroanthrachrysons in saurer Lösung.The diamido anthrachryson, which in the No. 81741 is obtained by reduction of the dinitroanthrachryson prepared according to patent specification No. 71964 in acidic solution. Das Verfahren zur Darstellung des Hexaoxyanthrachinons ist das im Haupt - Patente beschriebene. Es sei deshalb auf die dort angegebenen Versuchsbedingungen verwiesen und nur hinzugefügt, dafs man zur Isolirung des Farbstoffes die alkalische Lösung einfach ansäuert. The method for preparing the hexaoxyanthraquinone is that in the main patents described. Reference is therefore made to the test conditions given there and only added that the alkaline solution is simply acidified to isolate the dye. Das erhaltene Hexaoxyanthrachinon stimmt in seinen physikalischen, chemischen und coloristischen Eigenschaften vollständig mit dem in den Patentschriften Nr. 64418, 65375 und 661 53 beschriebenen Hexaoxyanthrachinon überein.The hexaoxyanthraquinone obtained is correct in its physical, chemical and coloristic properties Properties completely identical to those in Patent Nos. 64418, 65375 and 661 53 hexaoxyanthraquinone described.
