Description

  

      Zusatzpatent    zum Hauptpatent Nr. 191012.    Verfahren zur Herstellung eines neuen     Azofar        bstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          1-Amino-4-(p-oxy)-ätliyl-oxybenzol    mit 1,3  Diamiriobenzol-4-sulfonsäure vereinigt. Der  neue Farbstoff bildet ein gelbes Pulver, das  sich in Wasser mit brauner Farbe löst. Es  färbt Leder in gelbem Tone vollständig durch.

      <I>Beispiel:</I>    15,3 Teile     1-Ainino-4-(p-oxy)-äthyl-oxy-          benzol        wer(-en    in Wasser und Salzsäure ge  löst und bei 0-5   mit 6,9 Teilen Natrium  nitrit     diazotiert.    Die klare     Diazolösung    ver  einigt man bei     5-10     mit einer Lösung von  18,8 Teilen     1,3-Diaminobenzol-4-sulforisäure     in 300 Teilen Wasser und 30 Teilen Natrium-         karbonat.    Nach dem Verschwinden der     Diazo-          verbindung    wärmt man auf, salzt aus, fil  triert und trocknet. Man erhält ein gelbes  Pulver, das Leder in gelbem Tone vollständig  durchfärbt.



      Additional patent to main patent No. 191012. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when diazotized 1-amino-4- (p-oxy) -ethyl-oxybenzene is combined with 1,3 diamiriobenzene-4-sulfonic acid. The new dye forms a yellow powder that dissolves in water with a brown color. It completely dyes leather in a yellow shade.

      <I> Example: </I> 15.3 parts of 1-ainino-4- (p-oxy) -ethyl-oxy-benzene who (-en dissolved in water and hydrochloric acid and at 0-5 with 6.9 parts The clear diazo solution is combined at 5-10 with a solution of 18.8 parts of 1,3-diaminobenzene-4-sulforic acid in 300 parts of water and 30 parts of sodium carbonate. When the diazo compound has disappeared, it is warmed it is then salted out, filtered and dried to give a yellow powder which completely dyes the leather in a yellow shade.
