Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 202249.    Verfahren zur Herstellung eines neuen     wasserlöslichen    Derivates  der     Anthrachinonreihe.       Es wurde gefunden, dass man ein neues  wasserlösliches Derivat der     Anthrachinon-          reihe    erhält,     wenn:        man    2     Mol        Maleinsäure-          anhydrid    auf 1     Mol        1.4-Di-(ss-ogyäthyl-          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     reinblauem    Farbton und von sehr  guten Echtheitseigenschaften erzeugt.  



  <I>Beispiel:</I>  65 Teile     1.4-Di-(ss-ogyäthylamino)-an-          thrachinon    werden in 250 Teilen     Pyridin    mit  52 Teilen     Maleinsäureanhydrid    1/2     Stunde     zum Kochen erhitzt. Man     isoliert    das Pro  dukt durch Eingiessen in Wasser und An  säuern.    Das gleiche Produkt entsteht, wenn     statt          Pyridin        Dimethylanilin    verwendet     wird.  



  <B> Additional patent </B> 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 maleic anhydride are allowed to act on 1 mole of 1,4-di- (ss-ogyäthylamino) anthraquinone 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 pure blue shade and very good fastness properties on acetate silk.



  <I> Example: </I> 65 parts of 1,4-di- (ss-ogyäthylamino) -anthrachinon are heated to boiling for 1/2 hour in 250 parts of pyridine with 52 parts of maleic anhydride. The product is isolated by pouring it into water and acidifying it. The same product is obtained if dimethylaniline is used instead of pyridine.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen wasserlöslichen Derivates der Anthrachinon- reihe, dadurch gekennzeichnet, dass man 2 Mol Maleinsäureanhydrid auf 1 Mol 1.4-Di-(ss- ogyäthylamiuo)-anthrachinon in Gegenwart einer tertiären Base einwirken lässt. Claim: Process for the preparation of a new water-soluble derivative of the anthraquinone series, characterized in that 2 moles of maleic anhydride are allowed to act on 1 mole of 1,4-di- (ss- ogyäthylamiuo) -anthraquinone in the presence of a tertiary base. Das so erhaltene Produkt stellt getrocknet ein dunkles Pulver dar, das sich in verdünn ten Alkalien mit blauer Farbe löst und auf Acetatkunstseide sehr gleichmässige Drucke von reinblauem Farbtone und von sehr guten- Echtheitseigenschaften erzeugt. The product thus obtained is, when dried, a dark powder which dissolves in dilute alkalis with a blue color and produces very even prints of pure blue hues and very good fastness properties on acetate silk.
