Description

  

  Verfahren zur Herstellung eines     Anthracenderivates.       Im Hauptpatent und dessen Zusatzpatent  Nr. 106422 ist die Herstellung von     Anthra-          cenderivaten    durch Kondensation der     2,3-          Anthraehinonthioglykolkarbonsäure        resp.    der  2,3 -     Anthracenthioglykolkarbonsäure    zum  entsprechenden     2,3-Anthrachinon-        resp.        2,3-          Anthracenoxythionaphth.en    beschrieben wor  den.

   Diese Kondensation wurde durchge  führt, indem die     Thioglykolkarbonsäuren    mit  Kondensationsmitteln,     wieg    zum Beispiel       ssigsäure.anhydrid,    behandelt wurden.  



  Es wurde nun gefunden, dass man die  2,3-     Anthra.centhioglykolkarbonsäure    in das  2,3 -     Anthracenoxythionaphthen    überführen  kann, wenn man die Kondensation durch Er  wärmen der     2,3-Anthracenthioglykolkarbon-          s        äure    auf höhere Temperatur in Gegenwart  eines geeigneten Verdünnungsmittels, wie  zum Beispiel Wasser, bewirkt.  



  <I>Beispiel:</I>  10 Teile     2,3-Anthracenthioglykoll#:arbon-          säure    werden in 100 Teilen Wasser verteilt    und mehrere Stunden in einem geschlossenen  Gefäss auf 160 bis 1.70   C erhitzt. Nach dem  Erkalten wird das ausgeschiedene Reaktions  produkt     abfiltriert;    mit verdünnter     Sodalö-          sung    ausgekocht, nochmals filtriert, gewa  schen und getrocknet. Es stellt das     2,3-An-          thracenoxythion.aphthen    dar, das so in vor  züglicher Ausbeute     erhalten    wird.



  Process for the preparation of an anthracene derivative. In the main patent and its additional patent no. 106422 the production of anthracene derivatives by condensation of 2,3-anthraquinone thioglycolic acid, respectively. the 2,3 - Anthracenthioglykolkarbonsäure to the corresponding 2,3-Anthraquinone respectively. 2,3-Anthracenoxythionaphth.en was described.

   This condensation was carried out by treating the thioglycolic acids with condensing agents, such as ssigsäure.anhydrid, for example.



  It has now been found that you can convert the 2,3-Anthra.centhioglykolkarbonsäure in the 2,3 - Anthracenoxythionaphthen if you warm the condensation by He warm the 2,3-Anthracene thioglycol carboxylic acid to a higher temperature in the presence of a suitable diluent, such as water.



  <I> Example: </I> 10 parts of 2,3-anthracene thioglycoll #: carbonic acid are distributed in 100 parts of water and heated to 160 to 1.70 C in a closed vessel for several hours. After cooling, the precipitated reaction product is filtered off; Boiled with dilute soda solution, filtered again, washed and dried. It represents the 2,3-anthracene oxythionaphthene, which is obtained in this way in an excellent yield.
