  Zusatzpatent zum Hauptpatent     Nr.    202249.    Verfahren zur Herstellung eines neuen wasserlöslichen Derivates  der     Anthrachinonreihe.       Es wurde gefunden,     dass    man ein neues       wasserlösliehes    Derivat der     Anthrachinon-          reihe    erhält, wenn man 2     Mol        Bernsteinsäure-          anhydrid    auf<B>1</B>     Mol   <B>1.</B>     4-Di-(ss-oxyäthyl-          amino)-anthrachinon    in Gegenwart einer ter  tiären Base einwirken     lässt.     



  Das so erhaltene Produkt stellt getrock  net ein dunkles Pulver dar, das sich in ver  dünnten Alkalien mit blauer Farbe löst  und auf     Acetatkunstseide    sehr gleichmässige  Drucke von kräftigem,     reinblauem    Farbton  und von sehr guten Echtheitseigenschaften  erzeugt.  



  <I>Beispiel:</I>  <B>65</B> Teile<B>1.</B>     4-Di-(ss-oxyäthylamino)-an-          ihrachinon    werden in<B>250</B> Teilen     Pyridin    mit  <B>50</B> Teilen     Bernsteinsäureanhydrid    1/2 Stunde  zum Kochen erhitzt. Man isoliert das Pro  dukt durch Eingiessen in Wasser und vor  sichtiges     Aneuern,    wobei es kristallisiert.    Das gleiche Produkt entsteht, wenn statt       Pyridin        Dimethylanilin    verwendet wird.



  Additional patent to main patent no. 202249. Process for the production of a new water-soluble derivative of the anthraquinone series. It has been found that a new water-soluble derivative of the anthraquinone series is obtained if 2 moles of succinic anhydride are added to 1 mole 1 of 4-di- (β-oxyethyl - Amino) anthraquinone can act in the presence of a tertiary base.



  The product obtained in this way is a dark powder that dissolves in dilute alkalis with a blue color and produces very uniform prints of a strong, pure blue shade and very good fastness properties on acetate silk.



  <I> Example: </I> <B> 65 </B> parts of <B> 1. </B> 4-di- (ss-oxyäthylamino) -ane-aquinone become <B> 250 </B> Share pyridine with <B> 50 </B> parts succinic anhydride heated to boiling for 1/2 hour. The product is isolated by pouring it into water and careful warming, whereupon it crystallizes. The same product is obtained if dimethylaniline is used instead of pyridine.
