Description

  

      Zusatzpatent    zum Hauptpatent Nr. 181808.    Verfahren zur Herstellung eines     ehromierbaren    gelben     Azofarbstoffes.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Herstellung eines       chromierbaren    gelben     Azofarbstoffes,    welches  darin besteht, dass man dianotierte     ortho-          Aminobenzoesäure    mit 1 - (4"-     Methyl    - 4'       phenoxy-3'-sulfophenyl)-5-pyrazolon-3-carbon-          säureäthylester    kuppelt.

      <I>Beispiel:</I>    137 Gewichtsteile     ortho    -     Aminobenzoe-          säure    werden in üblicher Weise dianotiert  und mit einer     sodaalkalischen    Lösung von  418 Gewichtsteilen     1-(4"-Methyl-4'-phenoxy-          3'-        sulfophenyl)    - 5 -     pyrazolon    - 3 -     carbonsäure-          äthylester    vereinigt. Nach beendeter Kupp  lung wird der     Farbstoff    abgesaugt und ge  trocknet.  



  Er stellt ein gelbes, in     Wasser    leicht  lösliches Pulver dar, das Wolle in gelben  Tönen färbt, die sich nach erfolgter Behand  lung mit chromabgebenden Mitteln, wie zum  Beispiel     Kaliumbichromat    und     Schwefelsäure,       durch gute Echtheitseigenschaften, insbeson  dere sehr gute     Walkechtheit        auszeiobnen.  



      Additional patent to main patent No. 181808. Process for the production of an honorable yellow azo dye. The subject of the present Zusatzpa tentes is a process for the preparation of a chromable yellow azo dye, which consists in that dianotated ortho-aminobenzoic acid with 1 - (4 "- methyl - 4 'phenoxy-3'-sulfophenyl) -5-pyrazolone-3- carboxylic acid ethyl ester couples.

      <I> Example: </I> 137 parts by weight of ortho - aminobenzoic acid are dianotized in the usual way and mixed with a soda-alkaline solution of 418 parts by weight of 1- (4 "-methyl-4'-phenoxy-3'-sulfophenyl) - 5 - pyrazolone-3-carboxylic acid ethyl ester. When the coupling is complete, the dye is filtered off with suction and dried.



  It is a yellow powder that is easily soluble in water that dyes wool in yellow tones which, after treatment with chromium-releasing agents such as potassium dichromate and sulfuric acid, show good fastness properties, in particular very good millfastness.
