Description
Arbeitsverfahren zur Herstellung von Anthrachinon und dessen Derivaten. In dem Hauptpatent Nr. 84262 ist ein Ar beitsverfahren zur Herstellung von Anthra- chinon und dessen Derivaten aus Anthracen und dessen Derivaten durch Behandlung mit Sauerstoff beschrieben, darin bestehend, dass man in Gegenwart von sauerstoffhal tigen Verbindungen des Stickstoffes als Sauerstoffüberträger arbeitet. Die Stickstoff- Sauerstoffverbindungen wirken dabei als Katalysatoren. Die Ausführung des Verfah rens erfolgt zweckmässig in der Weise, dass man die zu oxydierenden Körper in geeig neten Flüssigkeiten löst oder suspendiert.
und zwar wird gemäss den Beispielen des Hauptpatentes Essigsäure als Lösungs- bezw. Suspensionsmittel benützt.
Es wurde nun gefunden, dass man mit gleichem Vorteil auch andere Säuren als Lösungs oder Suspensionsmittel benutzen kann, sowie dass man auch die sauren Lö sungsmittel in Mischung mit Lösungsmit teln, die sich an und für sich nicht eignen. wie z. B. Wasser, Nitrobenzol oder Diclilor- benzol, verwenden kann.

Process for the production of anthraquinone and its derivatives. In the main patent no. 84262 a work process for the production of anthracinone and its derivatives from anthracene and its derivatives by treatment with oxygen is described, consisting in the fact that one works in the presence of oxygen-containing compounds of nitrogen as an oxygen carrier. The nitrogen-oxygen compounds act as catalysts. The execution of the method is expediently carried out in such a way that the body to be oxidized is dissolved or suspended in suitable liquids.
namely acetic acid as a solution or according to the examples of the main patent. Suspending agent used.
It has now been found that other acids can also be used as solvents or suspending agents with the same advantage, and that the acidic solvents can also be mixed with solvents which are not suitable in and of themselves. such as B. water, nitrobenzene or diclilorbenzene can use.
