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.
