  Zusatzpatent zum Hauptpatent     Nr.   <B>297845.</B>    Verfahren zur Herstellung eines     Sulfonsäureamides    der     Anthrachinonreihe.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     SuHon-          säureamides    der     Anthraehinonreihe,    welches  darin besteht,     dass    man<B>1</B>     Mol    des nach der  Schweizer Patentschrift     Nr.295891        erhältli-          ehen        1,4-Di-(2',6-dimethyl)

  -phenyla#mino-          anthraehinondisulionsäurechlorides    mit 2     Mol          Aminomethan    kondensiert.  



  Im nachfolgenden Beispiel bedeuten die  Teile Gewichtsteile.  



  <I>Beispiel:</I>  Man verrührt das nach den Angaben der  Schweizer     Patentsc#I-1rift        Nr.   <B>295891</B> aus 44,6  Teilen     1,4-Di-(2',6-dimethyl)-phenylamino-          anthraehinon    erhältliche     Disulfonsäurechlorid     in Form einer wässerigen, neutralen Paste bei  <B><U>900</U></B> mit 200 Teilen Wasser und<B>65</B> Teilen       350./oi-er        Aminomethanlösung.    Hierauf erhöht  <B>kn</B>  man die Temperatur des Gemisches innert  einer Stunde auf 450 und rührt es bei dieser  Temperatur bis zur vollständigen Umsetzung  weiter, was etwa<B>5</B> Stunden beansprucht.

   Das  Kondensationsprodukt isoliert man aus der  wässerigen Suspension durch Filtrieren,     be-          f    reit es von der Mutterlauge durch Auswaschen  mit kaltem Wasser und trocknet es bei     800.     



  Das neue     Sulionsäureamid    der     Anthrachi-          nonreihe    ist ein     rotstiehig    blaues, in Wasser    unlösliches Pulver. Es löst sich mit blauer  Farbe in kalter<B>1</B>     1/o        iger        Natriumliydroxyd-          lösung,    in konzentrierter Schwefelsäure, in       (-r'lyeolmonoäthyläther    und in     Cyclohexanol.     Es dient zum Färben von Lacken und     plasti-          sehen    Massen.



  Additional patent to main patent no. <B> 297845. </B> Process for the production of a sulfonic acid amide of the anthraquinone series. The subject of the present patent is a process for the preparation of a SuHonic acid amide of the anthraehinone series, which consists in that <B> 1 </B> mol of the 1,4-di- (2 ', 6-dimethyl)

  -phenyla #mino- anthraehinondisulionsäurechlorides condensed with 2 mol of aminomethane.



  In the following example, the parts are parts by weight.



  <I> Example: </I> The mixture is stirred in accordance with the information in Swiss Patentsc # I-1rift No. <B> 295891 </B> from 44.6 parts of 1,4-di- (2 ', 6-dimethyl ) -phenylamino-anthraehinone available disulfonic acid chloride in the form of an aqueous, neutral paste at <B><U>900</U> </B> with 200 parts of water and <B> 65 </B> parts of 350./oi-er Aminomethane solution. The temperature of the mixture is then increased to 450 within an hour and it is stirred at this temperature until the reaction is complete, which takes about 5 hours.

   The condensation product is isolated from the aqueous suspension by filtration, it is freed from the mother liquor by washing with cold water and it is dried at 800 m.



  The new sulionic acid amide of the anthraquinone series is a reddish blue powder that is insoluble in water. It dissolves with a blue color in cold <B> 1 </B> 1 / o sodium hydroxide solution, in concentrated sulfuric acid, in -r'lyeol monoethyl ether and in cyclohexanol. It is used to color paints and plastic materials.
