Description

  

  Arbeitsverfahren zur Herstellung von     Anthrachinon    und dessen Derivaten.    Zur Herstellung von     Anthrachinon    und  dessen Derivaten aus entsprechenden Ver  bindungen niederer Oxydationsstufen sind  zahlreiche Verfahren bekannt., die auf der       Anwendung    verschiedener     Oxydationsmittel,     z. 13. Sauerstoffgas, beruhen.  



  Es Wurde nun gefunden, dass man An  thracen, die     Anthracenderivate    und die nie  deren     Oxydationsstufen    derselben mit Sauer  stoffgas wesentlich leichter in     Anthrachinon     und die entsprechenden Derivate verwan  deln kann, wenn man bei Gegenwart von       Stickstoff-Sauerstoffverbindungen        arbeit:et.     Die letzteren     wirken    als     Katalyten.     



  Die Wirkung des Verfahrens kann durch  Zugabe noch     weiterer        Sauerstoffüberträger     unterstützt werden.  



  Die Ausführung des Verfahrens erfolgt       zweckmässig    in der .Weise, dass man die  zu oxydierenden Körper in geeigneten Flüs  sigkeiten löst oder suspendiert. und hierauf  unter passenden Temperatur- und Druck  verhältnissen Sauerstoff einleitet, während  die sauerstoffhaltigen Stickstoffverbindungen    vor oder während des Oxydationsprozesses       zugeführt    werden.     Man    erhält nach dem  vorliegenden Arbeitsverfahren     Anthrachinon     und     Anthrachinon-Derivate    in grosser Rein  heit und vorzüglicher Ausbeute.

           Beispiel   <I>9:</I>    100 kg     Anthracen    werden in einem Kes  sel mit. 500--1000 kg konzentrierter Essig  s     iitire    bei     etwa        ä0--90      gründlich vermischt.  während man eine geringe Menge rauchen  der Salpetersäure     zuführt    und Sauerstoff  unter Druck einleitet. Die erforderliche  Menge Sauerstoff wird lebhaft absorbiert  und nach ungefähr 3-5 Stunden ist die Oxy  dation zu Ende geführt. Das entstandene       Authrachinon    wird in bekannter Weise iso  liert.

           Beispiel   <I>2:</I>    50 kg     Antlracen    werden in einem Kessel  mit     500    kg konzentrierter Essigsäure und  100     gr        Kobaltnitrat    bei 30-90   gerührt, wäh  rend man Sauerstoff, welchem ein geringer  Prozentsatz     Stickoxydgase    beigemischt ist,      einleitet. Die Oxydation ist gleichfalls nach  einigen Stunden beendet.  



  In ähnlicher Weise können Derivate, wie  z.     B.        Anthracensulfosäuren,    zu den     Chinon-          verbindungeri        oxydiert.    werden.



  Process for the production of anthraquinone and its derivatives. For the production of anthraquinone and its derivatives from corresponding Ver compounds of lower oxidation levels, numerous processes are known. Based on the use of various oxidants, eg. 13. Oxygen gas, based.



  It has now been found that anthracene, the anthracene derivatives and the never their oxidation stages of the same with oxygen gas can be transformed into anthraquinone and the corresponding derivatives much more easily if you work in the presence of nitrogen-oxygen compounds: et. The latter act as catalytes.



  The effect of the process can be supported by adding further oxygen carriers.



  The method is expediently carried out in such a way that the body to be oxidized is dissolved or suspended in suitable liquids. and then introduces oxygen under suitable temperature and pressure conditions, while the oxygen-containing nitrogen compounds are supplied before or during the oxidation process. The present working process gives anthraquinone and anthraquinone derivatives in great purity and in excellent yield.

           Example <I> 9: </I> 100 kg of anthracene are placed in a kettle with. 500--1000 kg of concentrated vinegar s iitire thoroughly mixed at about - 0--90. while a small amount of smoke is added to the nitric acid and oxygen is introduced under pressure. The required amount of oxygen is vigorously absorbed and after about 3-5 hours the oxidation is complete. The resulting authraquinone is isolated in a known manner.

           Example <I> 2: </I> 50 kg of anthracene are stirred in a kettle with 500 kg of concentrated acetic acid and 100 g of cobalt nitrate at 30-90, while oxygen, to which a small percentage of nitrogen oxide gases is mixed, is introduced. The oxidation is also over after a few hours.



  Similarly, derivatives such as. B. anthracene sulfonic acids, oxidized to the quinone compounds. will.
