Description

  

      Zusatzpatent    zum Hauptpatent Nr.<B>153486.</B>    Verfahren     zur        Herstellung    eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man dianotierte       2-Amino-l-phenol-4,6-disulfosäure    mit     5,6-          Benzo-2,4-dioxychiriolin    kuppelt und den er  haltenen     Farbstoff    mit einem chromabgeben  den Mittel behandelt.  



  Der erhaltene Farbstoff ist ein rotbraun  gefärbtes Pulver, das sich in     Wasser,    in  10     "/oiger    Natronlauge oder in 10     "/oiger    Soda  lösung mit roter und in konzentrierter Schwe  felsäure mit blauroter Farbe löst. Der Farb  stoff färbt Wolle aus schwefelsaurem Bade  in egalen bordeauxroten Tönen, die gut walk  und lichtecht sind.  



  <I>Beispiel:</I>  Eine aus 269 Teilen     2-Atnino-l-phenol-          4,6-disulfosäure    in bekannter Weise herge  stellte     Diazolösung    lässt man unter Rühren  zu einem mit Eis auf 10 " abgekühlten Ge  misch von 1000 Teilen Wasser, 220 Teilen       5,6-Benzo-2,4-dioxychinolin,    80 Teilen Ätz-         natron    und 120 Teilen Soda zufliessen.

   Der       Farbstoff    wird nach beendeter Kupplung mit  Kochsalz abgeschieden und     abfiltriert.    Der  erhaltene     Farbstoff    wird hierauf mit 7500  Teilen Wasser angerührt und mit einer       Chromsulfatlösung    versetzt, die hergestellt  wurde aus 88 Teilen Chromoxyd, 170 Teilen  konzentrierter Schwefelsäure und 600 Teilen  Wasser. Das Gemisch wird 18-20 Stunden       unter    Rückfuss zum Sieden erhitzt und hier  auf die Chromverbindung des Farbstoffes mit  Kochsalz abgeschieden,     abfiltriert    und ge  trocknet.



      Additional patent to main patent no. <B> 153486. </B> Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 2-amino-1-phenol-4,6-disulfonic acid is coupled with 5,6-benzo-2,4-dioxychirioline and the dye obtained is coupled with a chromium donating agent treated.



  The dye obtained is a red-brown colored powder which dissolves in water, in 10 "/ o strength sodium hydroxide solution or in 10" / o strength soda solution with red and in concentrated sulfuric acid with a blue-red color. The dye dyes wool from sulfuric acid baths in level burgundy shades that are easy to walk and lightfast.



  <I> Example: </I> A diazo solution prepared in a known manner from 269 parts of 2-atnino-1-phenol-4,6-disulfonic acid is allowed to add 1000 parts of water to a mixture of 1000 parts of water cooled with ice to 10 ", while stirring , 220 parts of 5,6-benzo-2,4-dioxyquinoline, 80 parts of caustic soda and 120 parts of soda flow.

   After coupling has ended, the dye is deposited with sodium chloride and filtered off. The dye obtained is then mixed with 7500 parts of water and treated with a chromium sulfate solution which has been prepared from 88 parts of chromium oxide, 170 parts of concentrated sulfuric acid and 600 parts of water. The mixture is heated to boiling under reflux for 18-20 hours and here deposited on the chromium compound of the dye with common salt, filtered off and dried.
