Description

  

      Zusatzpatent    zum Hauptpatent Nr. 188027.    Verfahren zur Herstellung eines     Azofarbstoffes.       Gegenstand des Hauptpatentes ist ein  Verfahren zur Herstellung eines neuen     Azo-          farbstoffes    durch Kuppeln der     Diazoverbin-          dung    von     1-Amino-4-nitrobenzol    mit     (N-Ox-          äthyl-N-[3-inethyl-phenyl]        )-ss-aminopropion-          säurenitril.     



  Es wurde nun gefunden, dass man einen  ähnlichen, wertvollen     Azofarbstoff    erhält,  wenn man die     Diazoverbindung    von     1-Amino-          2,6-dichlor-4-nitrobenzol    mit     (N-Oxäthyl-N-          [3    -     methyl    -     phenyl])        -ss    -     aminopropionsäure        -          nitril    kuppelt.  



  Der neue     Azofarbstoff    eignet sich vor  züglich zum Färben von     Zelluloseestern    und       -äthern,    die er in kräftig rotbraunen Tönen  färbt, ferner zur Herstellung gefärbter Fir  nisse. Spiritus- oder     Nitrozelluloselacke,    die  damit rotbraune Überzüge geben; Stearin.  Paraffin, Fette und Öle werden rotbraun ge  färbt.  



  <I>Beispiel:</I>  207 Teile     1-Amino-2,6-dichlor-4-nitroben-          zol    werden     diazotiert    und mit 214 Teilen         (N-Oxäthyl-N-[3-methyl-phenyl])        -ss-amino-          propionsäurenitril,    gelöst in 250 Teilen kon  zentrierter Salzsäure und 1000 Teilen Was  ser, gekuppelt. Die Kupplung ist nach kur  zer Zeit beendet. Der Farbstoff wird abge  saugt, säurefrei gewaschen und getrocknet.



      Additional patent to main patent No. 188027. Process for the production of an azo dye. The subject of the main patent is a process for the preparation of a new azo dye by coupling the diazo compound of 1-amino-4-nitrobenzene with (N-oxethyl-N- [3-ynethyl-phenyl]) -ss-aminopropion- acid nitrile.



  It has now been found that a similar, valuable azo dye is obtained if the diazo compound of 1-amino-2,6-dichloro-4-nitrobenzene is used with (N-oxethyl-N- [3-methyl-phenyl]) -ss - aminopropionic acid - nitrile couples.



  The new azo dye is particularly suitable for dyeing cellulose esters and ethers, which it dyes in strong red-brown tones, and also for producing colored varnishes. Spirit or nitrocellulose lacquers that give them red-brown coatings; Stearin. Paraffin, fats and oils are colored red-brown.



  <I> Example: </I> 207 parts of 1-amino-2,6-dichloro-4-nitrobenzene are diazotized and mixed with 214 parts of (N-oxethyl-N- [3-methyl-phenyl]) -ss- aminopropiononitrile, dissolved in 250 parts of concentrated hydrochloric acid and 1000 parts of water, coupled. The coupling ends after a short time. The dye is filtered off with suction, washed acid-free and dried.
