Description

  

      Zusatzpatent    zum Hauptpatent Nr. 101614.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man die     1-Oxy-          naphthalin-8-sulfamid-4-sulfosäure    mit     diazo-          tiertem        4-Chlor-2-amino-l-oxybenzol    kuppelt.  Der neue Farbstoff bildet ein schwärzlich  braunes Pulver und färbt Wolle     im    essigsau  ren Bade in blauroten Farbtönen, welche  beim     Nachchromieren        violett,,    beim Nach  kupfern rotviolett und echt werden.  



  <I>Beispiel:</I>  14,35 Teile     4-Chlor-2-amino-l-oxybenzol     werden in üblicher Weise     diazotiert    und zu  einer Lösung von 30,3 Teilen     1-Oxynaphtha-          lin-8-sulfamid-4-sulfosäure,    10 Teilen Natron  hydrat und 25 Teilen Soda in 20.0 Teilen  Wasser gegeben. Man rührt bei<B>5-10'</B> bis    die     Diazoverbindung    verschwunden ist und  scheidet den gebildeten Farbstoff durch Aus  salzen und Filtrieren ab.



      Additional patent to main patent no. 101614. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when 1-oxynaphthalene-8-sulfamide-4-sulfonic acid is coupled with diazotized 4-chloro-2-amino-1-oxybenzene. The new dye forms a blackish-brown powder and dyes wool in an acetic-acid bath in blue-red shades, which become violet when chrome-plated, and red-violet when copper is applied.



  <I> Example: </I> 14.35 parts of 4-chloro-2-amino-1-oxybenzene are diazotized in the usual way and converted into a solution of 30.3 parts of 1-oxynaphthalin-8-sulfamide-4- sulfonic acid, 10 parts of sodium hydrate and 25 parts of soda in 20.0 parts of water. The mixture is stirred at <B> 5-10 '</B> until the diazo compound has disappeared and the dye formed is separated off by salting out and filtering.
