Description

  

      Zusatzpatent    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     C,hromverbiridung    des Farb  stoffes aus     5-Nitro-2-diazo-l-pherrol    und     2-          (p-Tolylamino)-    5 -     oxynaphthalin    -7-     sulfosäure     dianotiert und mit     2-Amirio-5-oxynaphtalin-          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 Viskose, sowie     ohar-          gierte    Seide in grauen Tönen färbt.  



  <I>Beispiel:</I>  52 Teile des     Azofarbstoff"es,    erhalten durch  alkalische Kupplung von 33 Teilen     2-(p-To-          lylamino)    - 5 -     oxynaphthalin    -7 -     sulfosäure    mit  der     Diazoverbindung    aus 15 Teilen     5-Nitro-          2-amirro-l-pherrol,    werden mit einer aus 8,7  Teilen     Cr20s    enthaltenden     Ohromoxy        dhydrat-          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  des Rückstandes in verdünnter Natronlauge  wird in üblicher Weise     diazotiert.    Die     Diazo-          verbindung    lässt man unter Eiskühlung in eine  alkalische Lösung von 24 Teilen     2-Amino-5-          oxynaphthalin-    7 -     sulfosäure    einlaufen. Nach  beendeter Kupplung wird der     Disazofarbstoff     durch Kochsalz abgeschieden, filtriert und  hierauf getrocknet.



      Additional patent 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 C, hromverbirnung the dye from 5-nitro-2-diazo-1-pherrole and 2- (p-tolylamino) -5-oxynaphthalene-7-sulfonic acid dianotized and coupled with 2-Amirio-5-oxynaphthalene-7-sulfonic acid.



  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 viscose and hardened silk in gray tones.



  <I> Example: </I> 52 parts of the azo dye "es, obtained by alkaline coupling of 33 parts of 2- (p-tolylamino) -5-oxynaphthalene -7-sulfonic acid with the diazo compound from 15 parts of 5-nitro- 2-amirro-l-pherrol are mixed with an ohromoxy hydrate paste containing 8.7 parts of Cr20s, 4 parts of caustic

      72 parts of crystallized sodium sulphide and 14 parts of glycerin-made chromium solution are heated to boiling under a reflux condenser for several hours. After cooling, it is neutralized with acetic acid and filtered; after the residue has been dissolved in dilute sodium hydroxide solution, diazotization is carried out in the customary manner. The diazo compound is 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 disazo dye is precipitated with common salt, filtered and then dried.
