Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 143027.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man die  reduzierte Chromverbindung des Farbstoffes  aus     5-Nitro-2-diazo-l-phenol    und     2-Phenyl-          amino-5-oxynaphthalin-7-sulfosäure        diazotzert     und mit     2-Amino-5-oxynaphthalin-7-sulfosäure     kuppelt.  



  Der erhaltene Farbstoff bildet getrocknet  ein dunkles Pulver, das sich in Wasser und  in konzentrierter Schwefelsäure mit blau  grauer Farbe löst und     Viksose,    sowie char  gierte Seide in     grünlichgrauen    Tönen färbt.         Beispiel:

       50 Teile des     Azofarbstoffes,    erhalten durch  alkalische Kupplung von 32 Teilen     2-Phenyl-          amino-5-oxynaphthalin-7-sulfosäure    mit der       Diazoverbindung    aus 15 Teilen     5-Nitro-2-          amino-l-phenol,    werden mit einer aus 8,7  Teilen     Cr20s    enthaltenden     Chromoxydhydrat-          paste,    4 Teilen     Ätznatron,    72 Teilen kristal  lisiertem Schwefelnatrium und 14 Teilen  Glyzerin hergestellten Chromlösung einige  Stunden am     Rückflusskühler    zum Kochen er  hitzt.

   Man neutralisiert nach dem Erkalten    mit Essigsäure und filtriert. Nach dem Lösen  in Natronlauge wird in üblicher Weise     dia-          zotiert    ; hierauf wird die     Suspension    der       Diazoverbindung    unter Eiskühlung in eine  alkalische Lösung von 24 Teilen     2-Amino-5-          oxynaphthalin-7-sulfosäure    einlaufen gelassen.  Nach beendeter Kupplung wird der Farbstoff       abfiltriert    und getrocknet.



  <B> Additional patent </B> to main patent no. 143027. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the reduced chromium compound of the dye is diazotized from 5-nitro-2-diazo-1-phenol and 2-phenyl-amino-5-oxynaphthalene-7-sulfonic acid and diazotized with 2- Amino-5-oxynaphthalene-7-sulfonic acid couples.



  When dried, the dye obtained forms a dark powder which dissolves in water and in concentrated sulfuric acid with a blue-gray color and dyes Viksose and char gied silk in greenish-gray tones. Example:

       50 parts of the azo dye, obtained by alkaline coupling of 32 parts of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid with the diazo compound from 15 parts of 5-nitro-2-amino-1-phenol, are mixed with one of 8.7 Parts of chromium oxide hydrate paste containing Cr20s, 4 parts of caustic soda, 72 parts of crystallized sodium sulphide and 14 parts of glycerin-made chromium solution heated to boiling on a reflux condenser for a few hours.

   After cooling, it is neutralized with acetic acid and filtered. After dissolving in sodium hydroxide solution, diazotization is carried out in the usual way; the suspension of the diazo compound is then allowed to run into an alkaline solution of 24 parts of 2-amino-5-oxynaphthalene-7-sulfonic acid while cooling with ice. After the coupling has ended, the dye is filtered off and dried.
