Description

  

      Zusatzpatent    zum Hauptpatent Nr. 185944.         Verfahren    zur Herstellung eines unlöslichen     Azofarbstoffes.       Gemäss dem im Hauptpatent beschriebe  nen Verfahren erhält man einen     Acetatseide     in blaustichig roten Tönen anfärbenden un  löslichen     Azofarbstoff,    wenn man     4-Nitro-l-          aminobenzol        diazotiert    und die     Diazoverbin-          dung    mit     1-Butyl-3-oxy-7-chlortetrahydrochi-          nolin    kuppelt.  



  Wie nun weiter gefunden wurde, erhält  man einen     Farbstoff    von ähnlichen Eigen  schaften, wenn man     6-Chlor-2.        4-dinitro-l-          aminobenzol        diazotiert    und die     Diazoverbin-          dung    mit     1-n-Butyl-3-methoxy-7-methyl-          tetrahydrochinolin    kuppelt.

      <I>Beispiel:</I>    21,8 Teile     6-Chlor-2.4-dinitro-l-amino-          benzol    werden in der üblichen Weise     diazo-          tiert.    Die     Diazoverbindung    lässt man in eine  eisgekühlte Lösung von 24,6     Teilen.    1-n-         Butyl-3-methoxy-    7     -methyl-tetrahydrochino-          lin    in der entsprechenden     Menge    verdünnter  Salzsäure einlaufen und stumpft zur Been  digung der Kupplung mit     Natriumacetat    ab.

    Der erhaltene Farbstoff färbt     Acetatseide    im       Seifensuspensionsbad    rötlich blau.



      Additional patent to main patent no. 185944. Process for the production of an insoluble azo dye. According to the process described in the main patent, an insoluble azo dye which stains acetate silk in bluish red shades is obtained if 4-nitro-l-aminobenzene is diazotized and the diazo compound is coupled with 1-butyl-3-oxy-7-chlorotetrahydroquinoline .



  As has now been found further, a dye of similar properties is obtained if 6-chloro-2. 4-dinitro-l-aminobenzene is diazotized and the diazo compound is coupled with 1-n-butyl-3-methoxy-7-methyl-tetrahydroquinoline.

      <I> Example: </I> 21.8 parts of 6-chloro-2,4-dinitro-1-aminobenzene are diazo- tated in the usual way. The diazo compound is left in an ice-cold solution of 24.6 parts. 1-n-Butyl-3-methoxy-7-methyl-tetrahydroquinoline is poured in in the appropriate amount of dilute hydrochloric acid and blunted with sodium acetate to complete the coupling.

    The dye obtained gives the acetate silk a reddish blue color in the soap suspension bath.
