Description

  

  verfahren zur .Herstellung eines     Anthraeenderivates.       Es wurde gefunden; dass man ein neues       Anthracenderivat    enthält, wenn man ein     An-          thrachinon-2-glyzin-3-karbonsäure    mit Kon  densationsmitteln behandelt.  



  Das neue     Anthracenderivat,    das als ein  Abkömmling des     2,3-Anthrachinonindoxyls     aufzufassen ist, bildet     bräunlichgelbe    Kristalle,  welche sich in kalter, konzentrierter Schwefel  säure mit orangeroter Farbe lösen und mit  Wasser als     grünlichgelbe    Flocken ausgefällt  werden. In Nitrobenzol ist es mit gelbbrauner  Farbe löslich. Mit     Hydrosulfit    und Natron  lauge entsteht eine     Küpe,    die zunächst braun  ist und nach einiger Zeit nach     olivegrün    um  schlägt. Es bildet ein wertvolles Ausgangs  material zur Darstellung von Farbstoffen.

         Beispiel:     29 Teile     Arithrachinon-2-glyzin-3-karbon-          säure    und 15. Teile entwässertes Natrium  acetat werden in 290 Teilen     Essigsäurean-          hydrid    einige Zeit rückfliessend gekocht. Vor  übergehend entsteht eine .braune Lösung,    woraus sich nach kurzer Zeit     bräunlichgelbe     Kristalle' abscheiden. Diese werden nach dem  Erkalten abgesaugt, zuerst mit Eisessig, dann  mit Wasser gewaschen und getrocknet.



  process for .production of an anthraeene derivative. It was found; that one contains a new anthracene derivative if one treats an anthrachinone-2-glycine-3-carboxylic acid with condensation agents.



  The new anthracene derivative, which is to be understood as a derivative of 2,3-anthraquinone indoxyl, forms brownish-yellow crystals, which dissolve in cold, concentrated sulfuric acid with an orange-red color and are precipitated as greenish-yellow flakes with water. It is soluble in nitrobenzene with a yellow-brown color. With hydrosulphite and caustic soda, a vat is created that is initially brown and then turns olive-green after a while. It is a valuable starting material for the representation of dyes.

         Example: 29 parts of arithraquinone-2-glycine-3-carbonic acid and 15 parts of dehydrated sodium acetate are refluxed for some time in 290 parts of acetic anhydride. A "brown solution" is formed before a transition, from which brownish-yellow crystals separate out after a short time. After cooling, these are suctioned off, washed first with glacial acetic acid, then with water and dried.
