      Zusatzpatent    zum Hauptpatent Nr. 203430.         Verfahren    zur Herstellung eines Farbstoffes der     Anthrachinonreihe.       Im Hauptpatent ist ein Verfahren zur Her  stellung eines wertvollen neuen Farbstoffes  der     Anthrachinonreihe    beschrieben, welches  darin besteht, dass man auf     Anthrachinonab-          kömmlinge    vom allgemeinen Aufbau  
EMI0001.0007     
    worin X und Y austauschfähige Reste be  deuten, die die Überführung der     Anthrachirron-          abkömmlinge    in ihre     Leukoverbindungen    ge  statten,

   teilweise in Form ihrer     Leukover-          bindungen    mit einem Gemisch von     Amino-          2.3-proparrdiol    und     Amirioäthanol    umsetzt und  vorhandene     Leukoverbindungen    oxydiert.  



  Es wurde nun gefunden, dass man den  selben Farbstoff erhält, wenn man     Leuko-          verbindungen    von     Anthrachinonabkömmlingen     vom allgemeinen Aufbau  
EMI0001.0020     
    worin     ä    und Y austauschfähige Reste be  deuten, die die Überführung der     Anthrachinon-          abkömmlinge    in ihre     Leukoverbindungen    ge  statten, mit einem     Geneisch    von     Amino-2.3-          propandiol    und     Aminoäthanol    umsetzt und  die so erhaltene     Leukoverbindung    oxydiert.  



       Ausgangsstoffe    sind z. B.     Leuko-1.4-Dioxy-          anthrachinon,        Leuko-1.4-Diaminoanthrachi-          non,Leuko-l-amino.4-oxyanthrachinon,        Leuko-          1-amino-4-methoxyarrthrachinon,        Leuko-l-oxy-          4.methoxy-anthrachirron        undLeuko-1.4-dimeth-          oxyanthrachinon.     



  Es ist nicht erforderlich, von den. fertigen       Leukoverbindungen    auszugehen, sondern man  kann auch die     Anthrachinonabkömmlirrge    in  Gegenwart eines Reduktionsmittels wie Zink  staub oder     Natriumhydrosulfit    verwenden.      Der so erhaltene Farbstoff ist identisch  mit dem nach dem Verfahren des Haupt  patentes erhaltenen.  



  <I>Beispiel:</I>  Eine Mischung von 30 Teilen     Leuko-1.4-          diaminoanthrachinon,    13,6 Teilen     1-Amino-          2.3-propandiol,    9,2 Teilen     Aminoäthatrol    und  110 Teilen     Isobutanol    wird etwa 6 Stunden  lang am     Rückflusskühler    unter Rühren ge  kocht. Dann lässt     rnan    erkalten und saugt  die in Form grünlich glänzender Kristalle  abgeschiedene     Leukoverbindung    ab.

   Durch  Erhitzen mit 4 Teilen Nitrobenzol unter Zu  satz von 0,1 Teil     Piperidin    wird diese     Leuko-          verbindung        zurn        Farbstoff    oxydiert, der sich  in Nitrobenzol mit tiefblauer Farbe löst und  beim Erkalten sich in schönen blauen Kri  stallen abscheidet. Der so erhaltene Farbstoff  wird durch Lösen in warmem     Wasser    und  Filtrieren von dem     gleicbfalls    in geringer  Menge     mitentstandenen        1.4-Diätharrolamirro-          anthrachinon    befreit.

   Durch Eindampfen des  blauen Filtrats wird ein Farbstoff erhalten,  der in seinen     färberischen    Eigenschaften mit  dem nach dem Verfahren des Hauptpatentes  erhaltenen übereinstimmt.



      Additional patent to main patent no. 203430. Process for the production of a dye of the anthraquinone series. The main patent describes a process for the manufacture of a valuable new dye of the anthraquinone series, which consists in relying on anthraquinone derivatives of the general structure
EMI0001.0007
    where X and Y denote exchangeable residues which enable the conversion of the anthrachirron derivatives into their leuco compounds,

   partially in the form of their leuco compounds with a mixture of amino-2,3-proparrdiol and amirioethanol and oxidizes existing leuco compounds.



  It has now been found that the same dye is obtained if leuco compounds of anthraquinone derivatives of the general structure are used
EMI0001.0020
    where and Y are interchangeable radicals which enable the conversion of the anthraquinone derivatives into their leuco compounds, reacts with a mixture of amino-2,3-propanediol and aminoethanol and oxidizes the leuco compound thus obtained.



       Starting materials are z. B. leuco-1,4-dioxyanthraquinone, leuco-1,4-diaminoanthraquinone, leuco-1-amino.4-oxyanthraquinone, leuco-1-amino-4-methoxyarrthraquinone, leuco-1-oxy-4.methoxy-anthrachirron and leuko 1,4-dimethoxyanthraquinone.



  It is not required by the. ready-to-use leuco compounds, but you can also use the anthraquinone derivatives in the presence of a reducing agent such as zinc dust or sodium hydrosulfite. The dye obtained in this way is identical to that obtained by the process of the main patent.



  <I> Example: </I> A mixture of 30 parts of leuco-1,4-diaminoanthraquinone, 13.6 parts of 1-amino-2,3-propanediol, 9.2 parts of aminoethatrol and 110 parts of isobutanol is refluxed for about 6 hours with stirring cooked. Then let it cool down and suck off the leuco compound deposited in the form of greenish, shiny crystals.

   By heating with 4 parts of nitrobenzene with the addition of 0.1 part of piperidine, this leuco compound is oxidized to the dye, which dissolves in nitrobenzene with a deep blue color and separates out in beautiful blue crystals on cooling. The dye obtained in this way is freed from the 1,4-dietharrolamirro-anthraquinone, which is also formed in small quantities, by dissolving it in warm water and filtering.

   Evaporation of the blue filtrate gives a dye which, in terms of its coloring properties, corresponds to that obtained by the process of the main patent.
