Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 143027.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen       rnetallhaltigen    Farbstoff erhält, wenn man  die reduzierte Chromverbindung des Farb  stoffes aus     5-Nitro-2-diazo-l-phenol    und     2-          Pheriylamirio-5-oxynaphthaliri-7-sulfosäure        dia-          zotiert    und mit     1,8-Dioxyriaphthälin-3,6-di-          sulfosäure    kuppelt.  



  Der erhaltene     Farbstoff    bildet getrocknet  ein dunkles Pulver, das sich in Wasser mit  blaugrauer, in konzentrierter Schwefelsäure  mit schmutzig violetter Farbe löst und Vis  kose, sowie unbeschwerte Seide in grauen  Tönen färbt.  



  <I>Beispiel:</I>  50 Teile des     Azofarbstoffes,    erhalten durch  alkalische Kupplung von 32 Teilen     2-Phenyl-          amino-5-oxyriaphthalin-7-sulfosäure    mit der       Diazoverbindung    aus 15 Teilen     5-Nitro-2-          amino-l-phenol,    werden mit einer aus 8,7 Teilen       Cr20s    enthaltenden     Chromoxydhydratpaste,     4 Teilen     Ätznatron,    72 Teilen kristallisiertem  Schwefelnatrium und 14 Teilen Glyzerin her  gestellten Chromlösung einige Stunden am       Rückflusskühler    zum Kochen erhitzt. Man  neutralisiert nach dem Erkalten mit Essig-    säure und filtriert.

   Nach denn Lösen in Na  tronlauge wird in üblicher Weise dianotiert.  



  Die Suspension der     Diazoverbindung    wird  hierauf unter Eiskühlung in eine alkalische  Lösung von 32 Teilen     1,8-Dioxyriaphthalin-          3,6-disulfosäure    einlaufen gelassen. Nach  beendeter Kupplung wird der     Disazofarbstoff          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-methylamirio-5-oxynaphthalen-7-sulfonic acid and diazotized with 1 , 8-Dioxyriaphthalene-3,6-disulfonic acid couples.



  The dye obtained forms a dark powder when dried, which dissolves in water with a blue-gray color, in concentrated sulfuric acid with a dirty violet color and dyes viscose and carefree silk in gray tones.



  <I> Example: </I> 50 parts of the azo dye, obtained by alkaline coupling of 32 parts of 2-phenylamino-5-oxyriaphthalene-7-sulfonic acid with the diazo compound from 15 parts of 5-nitro-2- amino-1- phenol, are heated with a chromium oxide hydrate paste containing 8.7 parts of Cr20s, 4 parts of caustic soda, 72 parts of crystallized sodium sulphide and 14 parts of glycerin made chromium solution for a few hours on a reflux condenser. After cooling, it is neutralized with acetic acid and filtered.

   After dissolving in sodium hydroxide solution, dianotation is carried out in the usual manner.



  The suspension of the diazo compound is then allowed to run into an alkaline solution of 32 parts of 1,8-dioxyriaphthalene-3,6-disulfonic acid while cooling with ice. After the coupling has ended, the disazo dye is filtered off and dried.
