      Zusatzpatent    zum Hauptpatent Nr. 241209.         Verfahren    zur Herstellung eines neuen     Anthraebinon-Farbstoffes.       Gegenstand vorliegender Erfindung ist ein  Verfahren zur Herstellung eines neuen     An-          thraehinon-Küpenfarbstoffes    durch Umset  zen von     1,4-Diaminoanthrachinon    mit einem  Gemisch von     p-Methylsulfonyl-benzoylchlo-          rid    und     p-n-Butylsulfonyl-benzoylchlorid.     



  Der so erhaltene neue Farbstoff färbt  Baumwolle aus einer     bläulichgrauen,    alka  lischen     Hydrosulfitküpe    in hellen scharlach  roten Farbtönen von sehr guten Echtheits  eigenschaften, wobei die so erzielten Fär  bungen insbesondere in bezug auf ihre Echt  heit beim Kochen in der     Küpe    denjenigen  Färbungen überlegen sind, welche bei Ver  wendung von     1,4-Di-(p-methylsulfonyl-ben-          zoylamino)-anthrachinon    oder von     1,4-Di-(p-          n-butylsulfonyl-benzoylamino)    -     anthrachinon     erhalten werden.  



  Die Erfindung sei durch das nachste  hende Beispiel erläutert. Die Teile bedeuten  Gewichtsteile.  



       Beispiel:     9 Teile     p-Methylsulfonyl-benzoesäure    und  4,84 Teile     p-Butylsulfonyl-benzoesäure    wer  den durch Behandeln mit überschüssigem       Thionylchlorid    in einer     Nitrobenzollösung     in ein Gemisch der entsprechenden Säure  chloride übergeführt und dieses Gemisch  wird hierauf während     2i/2    Stunden bei  120  C mit 4,76 Teilen     1,4-Diaminoanthra-          chinon    erhitzt.

   Alsdann wird das Gemisch  gekühlt und der Festkörper, der sich hierbei  ausscheidet,     abfiltriert    und so lange durch  Einleiten eines     Wasserdampfstromes    erhitzt,  bis alles Nitrobenzol entwichen ist.    Der so erhaltene Farbstoff färbt Baum  wolle aus einer     bläulichgrauen,    alkalischen       Hydrosulfitküpe    in hellen scharlachroten  Farbtönen von sehr guten Echtheitseigen  schaften, wobei die so erzielten Farbtöne  insbesondere in bezug auf ihre Echtheit beim  Kochen in der     Küpe    denjenigen Färbungen  überlegen sind, welche bei der     Verwendung     von     1,4-Di-(p-methylsulfonyl-benzoylamino)

  -          anthraehinon    oder von     1,4-Di-(p-n-butylsul-          fonyl-benzoylamino)        -anthrachinon    erhalten  werden.



      Additional patent to main patent No. 241209. Process for the production of a new anthraebinone dye. The present invention relates to a process for the preparation of a new anthraehinone vat dye by reacting 1,4-diaminoanthraquinone with a mixture of p-methylsulfonyl-benzoyl chloride and p-n-butylsulfonyl-benzoyl chloride.



  The new dye obtained in this way dyes cotton from a bluish-gray, alkaline hydrosulfite vat in light scarlet red shades of very good fastness properties, the dyeings thus obtained, especially with regard to their authenticity when boiled in the vat, are superior to those dyeings that are used in Use of 1,4-di- (p-methylsulfonyl-benzoylamino) -anthraquinone or of 1,4-di- (p-n-butylsulfonyl-benzoylamino) - anthraquinone can be obtained.



  The invention is illustrated by the following example. The parts mean parts by weight.



       Example: 9 parts of p-methylsulfonyl-benzoic acid and 4.84 parts of p-butylsulfonyl-benzoic acid are converted into a mixture of the corresponding acid chlorides by treatment with excess thionyl chloride in a nitrobenzene solution and this mixture is then converted at 120 ° C. for 2½ hours heated with 4.76 parts of 1,4-diaminoanthraquinone.

   The mixture is then cooled and the solid that separates out is filtered off and heated by passing in a stream of steam until all of the nitrobenzene has escaped. The dye obtained in this way dyes cotton from a bluish-gray, alkaline hydrosulfite vat in light, scarlet-red shades with very good fastness properties, the shades obtained in this way, in particular with regard to their fastness when boiled in the vat, are superior to those dyes which are obtained when using 1 , 4-di (p-methylsulfonyl-benzoylamino)

  - Anthraehinone or 1,4-di- (p-n-butylsulfonyl-benzoylamino) -anthraquinone are obtained.
