Description

  

  Verfahren zur Herstellung eines wasserlöslichen     Azofarbstoffes.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Herstellung eines  wasserlöslichen     Azofarbstoffes,    welches da  durch gekennzeichnet ist, dass man die     Diazo-          verbindung    von     1-Amino-3-sulfonsäuredime-          thylamid-benzol-6-sulfonsäure    mit     1-(2'-Chlor-          6'-        methyl-4'-sulfophenyl)-    3     -inethyl-5-pyrazo-          lon    kuppelt.

      <I>Beispiel:</I>    Die aus 280 Gewichtsteilen     1-Amino-3-          sulfonsäuredimethylamid-benzol-6-sulfonsäure     erhaltene     Diazosuspension    wird mit einer       lackmusneutralen    Lösung von 301,5 Gewichts  teilen     1-(2'-Chlor-6'-methyl-4'-sulfophenyl)-3-          methyl-5-pyrazolon    in Gegenwart von Na  triumacetat gekuppelt. Nach beendeter Kupp  lung wird der Farbstoff abgesaugt und ge  trocknet.    Er stellt ein gelbes, in Wasser lösliches  Pulver dar, das     grünstichiggelbe    Färbungen  von guter Licht-, Wasser- und Waschecht  heit auf Wolle ergibt.



  Process for the preparation of a water-soluble azo dye. The subject of the present additional patent is a process for the production of a water-soluble azo dye, which is characterized in that the diazo compound of 1-amino-3-sulfonic acid dimethylamide-benzene-6-sulfonic acid with 1- (2'-chlorine - 6'-methyl-4'-sulfophenyl) -3-ynethyl-5-pyrazolone couples.

      <I> Example: </I> The diazo suspension obtained from 280 parts by weight of 1-amino-3-sulfonic acid dimethylamide-benzene-6-sulfonic acid is mixed with a litmus-neutral solution of 301.5 parts by weight of 1- (2'-chloro-6'- methyl-4'-sulfophenyl) -3-methyl-5-pyrazolone coupled in the presence of sodium acetate. After coupling is complete, the dye is suctioned off and dried. It is a yellow, water-soluble powder that produces greenish-yellow dyeings of good light, water and washfastness on wool.
