Description

  

      Zusatzpatent    zum     13auptpatent    Nr. 101614.         Verfahren    zur Herstellung eines neuen     Azofarüstoffes.       Es wurde gefunden,     da,ss        man    einen neuen       Azofarbstoff    erhält, wenn man die     1-Oxy-          naphthalin-8-sulfamid-4-sulfosäure    mit     diazo-          tiertem        4-Nitro-6-chlor-l-oxy-2-aminobenzol     kuppelt.

   Der neue Farbstoff bildet ein dunk  les Pulver und färbt Wolle im essigsauren  Bade in schwarzvioletten Farbtönen, welche  beim     Nachchromieren        hellbraunviolett,    beim  Nachkupfern blaurot und echt werden.  



  <I>Beispiel:</I>  1.8,85 Teile     4-1\Titro-6-ehlor-l-oxy-2-amino-          benzol    werden in üblicher Weise     diazotiert     und zu einer Lösung von 80,3 Teilen     1-Oxy-          naphthalin-8-sulfamid-4-sulfosäure,    10 Teilen       Natronhydrat    und 25 Teilen Soda in 200 Tei  len Wasser gegeben. Man     rührt    bei 5 bis    10  , bis die     Dia\overbindung    verschwunden  ist und scheidet den gebildeten Farbstoff  durch     Aussalzen    und Filtrieren ab.



      Additional patent to the 13th main patent no. 101614. Process for the production of a new azo-aromatic substance. It has been found that a new azo dye is obtained if 1-oxynaphthalene-8-sulfamide-4-sulfonic acid is coupled with diazotized 4-nitro-6-chloro-1-oxy-2-aminobenzene.

   The new dye forms a dark powder and dyes wool in the acetic acid bath in black-violet shades, which become light brown-violet when chrome-plating and blue-red and real when copper-plating.



  <I> Example: </I> 1.8.85 parts of 4-1 \ Titro-6-chloro-1-oxy-2-aminobenzene are diazotized in the usual way and a solution of 80.3 parts of 1-oxy- naphthalene-8-sulfamide-4-sulfonic acid, 10 parts of sodium hydrate and 25 parts of soda in 200 Tei len water. The mixture is stirred at 5 to 10 until the diamond bond has disappeared and the dye formed is separated off by salting out and filtering.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, da.ss man die 1-Oxynaphthalin-8-sulfamicl-4-sulfo- säure mit diazotiertem 4-Nitro-6-chlor-l-oxy- 2-aminobenzol kuppelt. Der neue Farbstoff bildet ein dunkles Pulver und färbt Wolle im essigsauren Bade in schwarzvioletten Farbtönen, welche beim Nachchromieren hell braunviolett, beim Nachkupfern blaurot und echt werden. PATENT CLAIM: Process for the production of a new azo dye, characterized in that 1-oxynaphthalene-8-sulfamicl-4-sulfonic acid is coupled with diazotized 4-nitro-6-chloro-1-oxy-2-aminobenzene. The new dye forms a dark powder and dyes wool in the acetic acid bath in black-violet shades, which become light brown-violet when chromium plating and blue-red and real when copper-plating.
