  <B>Zusatzpatent</B> zum Hauptpatent Nr. 196173.    Verfahren zur Herstellung eines neuen     Farbstoiipräparates.       Es wurde gefunden, dass man ein neues,  lösliches     Farbstoffpräparat    erhält, wenn man  auf     1,5-p-Dianisoyl-diamino-4,

  8-dioxyanthra-          chinon    in Gegenwart von     Pyridiu        Benzoe-          säure-3-sulfochlorid        einwirken        lässt.        Hier-          durch    werden die OH-Gruppen des     Anthra-          chinonderivates        sulfobenzoyliert.

         entspricht,    kann zum Färben oder Drucken  von     Textilien        verwendet        werden.       <I>Beispiel:

  </I>  53,8 Teile     1,5-p-Dianisoyl-diamino-4,8-di-          oxyanthrachinon    werden mit 500 Teilen Py-    Das neue     Farbstoffpräparat    stellt     ein     braunes     Pulver    dar, das sich in Wasser mit  braungelber Farbe unter Bildung einer Lö  sung, aus welcher durch Alkalien der Aus  gangsfarbstoff regeneriert     wird,    löst.

   Das  neue     Farbstoffpräparat,    das der Formel         ridin        verrührt.    Dazu gibt man 66 Teile       Benzoesäure-m-sulfochlorid,    steigert die Tem  peratur auf etwa 90   und hält bei 90 bis 95  ,  bis sich eine Probe in Wasser klar     auflöst.     Nach dem Abtreiben des     Pyridins    im Va  kuum wird das     Reaktionsprodukt    durch Lö-      sen in wenig Wasser und Fällen mit gesättig  ter Kochsalzlösung in     fester    Form gewonnen.



  <B> Additional patent </B> to main patent no. 196173. Process for the production of a new coloring agent preparation. It has been found that a new, soluble dye preparation is obtained if you click on 1,5-p-dianisoyl-diamino-4,

  8-dioxyanthraquinone in the presence of Pyridiu benzoic acid 3-sulfochloride can act. As a result, the OH groups of the anthraquinone derivative are sulfobenzoylated.
EMI0001.0015
         can be used for dyeing or printing textiles. <I> example:

  </I> 53.8 parts of 1,5-p-dianisoyl-diamino-4,8-di-oxyanthraquinone with 500 parts of Py- The new dye preparation is a brown powder that turns brownish-yellow in water to form a Lö solution, from which the starting dye is regenerated by alkalis, dissolves.

   The new dye preparation that mixes the formula ridin. 66 parts of benzoic acid-m-sulfochloride are added, the temperature is increased to about 90 and held at 90 to 95 until a sample dissolves clearly in water. After the pyridine has been driven off in a vacuum, the reaction product is obtained in solid form by dissolving it in a little water and precipitating it with saturated sodium chloride solution.
