Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Azofarbstoffes,     dadurch gekennzeichnet, dass man die     Diazo-          verbindung    von     6-Chlor-2-amino-l-oxybenzol     mit dem Einwirkungsprodukt von 1     Mol.          Chlorkohlensäureäthylester    und 1     Mol.    Essig  säureanhydrid auf 1.     5-Diamino-3-oxynaphtha-          lin-7-sulfonsäure    vereinigt.  



  Der     Farbstoff    ist getrocknet ein dunkles  Pulver, das sich in verdünnten Säuren mit  roter, in     Natriumcarbonatlösung    mit blauer  und in konzentrierter     Schwefelsäure    mit blau  stichig-roter Farbe löst, und färbt Wolle in  roten Tönen, die beim     Ohromieren    in rot  stichig-graue Töne von sehr guter Licht-,  Walk-,     Carbonisier-    und     Pottingechtheit    über  gehen.  



       Beispiel:     14,3 Gewichtsteile     6-Chlor-2-amino-l-oxy-          benzol    werden     diazotiert.    Die     Diazolösung     lässt man in     eine    überschüssiges Natrium-         carbonat    enthaltende Lösung von 37 Gewichts  teilen einer Kupplungskomponente einlaufen,  die man erhält, wenn man 25,4     Gewichtst        1e     1 .

   5     -Diamino    - 3 -     oxynaphthalin-    7 -     sulfonsäure     nacheinander mit 11 Gewichtsteilen     Chlor-          kohensäureäthylester    und dann bis     zur    Be  endigung der     Acylierung    mit     Essigsäure-          anhydridinwässerigerLösung    behandelt. Nach  beendeter     Kupplung    wird der     Farbstoff    ab  geschieden und getrocknet.



  Process for the preparation of an azo dye. The present patent relates to a process for the production of an azo dye, characterized in that the diazo compound of 6-chloro-2-amino-1-oxybenzene is mixed with the action product of 1 mol. Of ethyl chlorocarbonate and 1 mol. Of acetic anhydride to 1. 5-diamino-3-oxynaphthalin-7-sulfonic acid combined.



  The dyestuff is a dried dark powder that dissolves in dilute acids with red, in sodium carbonate solution with blue and in concentrated sulfuric acid with bluish-red color, and it dyes wool in red tones, which when odorized in red, cast-gray tones of very good fastness to light, fulling, carbonising and potting.



       Example: 14.3 parts by weight of 6-chloro-2-amino-1-oxybenzene are diazotized. The diazo solution is allowed to run into a solution of 37 parts by weight of a coupling component which contains excess sodium carbonate and which is obtained when 25.4 parts by weight of 1e 1.

   Treated 5-diamino-3-oxynaphthalene-7-sulfonic acid in succession with 11 parts by weight of ethyl chloroate and then with acetic anhydridine aqueous solution until the acylation is complete. After the coupling has ended, the dye is separated off and dried.
