Description

  

  Zusatzpatent zum Hauptpatent     Nr.    111564.    Verfahren zur     Ilerstellung    eines neuen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man den     Azc>fa.rb-          stoff,    welcher durch Kuppeln von     diazotier-          ter        4-Sulf        o-2-amino-l-phenol-6-karbonsäure     mit dem     Acete.-sigarylid    der     Anthranilsäure     erhalten wird, mit     Chromformiat    behandelt.

    Der neue     Parbstoff    bildet ein     olivebraunes     Pulver, löst sich in Wasser mit gelber Farbe  und färbt Wolle aus saurem Bade in sehr  gleichmässigen, echten gelben Tönen an. Auf  Baumwolle mit Chrombeizen gedruckt, er  zeugt er sehr reine und echte gelbe Töne.  



       ReMpiel:     <B>50</B> Teile des     Fa.rbstoffes    aus     4-Sulfo-2-          diazo-l-phenol-6-kar'bonsä,ure    und dem     Acot-          essigarylid    der     Anthranilsäure    werden in  <B>100</B> Teilen Wasser     "elöst    und bei Siedetem  peratur einige Zeit mit<B>32</B> Teilen     Chrom-          formiat    behandelt. Die Lösung wird sodann    eingedampft und der Farbstoff mit     Koch-          salz    gefällt.



  Additional patent to the main patent No. 111564. Process for the production of a new dye. It has been found that a new dye is obtained if the Azc> fa.rb- fabric, which is obtained by coupling diazotized 4-sulfo-2-amino-1-phenol-6-carboxylic acid with the acetone. sigarylid of anthranilic acid is obtained, treated with chromium formate.

    The new paraffin forms an olive-brown powder, dissolves in water with a yellow color and dyes wool from an acid bath in very even, genuine yellow tones. Printed on cotton with chrome stain, it produces very pure and real yellow tones.



       ReMpiel: <B> 50 </B> parts of the dye made from 4-sulfo-2-diazo-1-phenol-6-carboxylic acid and the acot-acetic arylide of anthranilic acid are used in <B> 100 </ B> parts of water "are dissolved and treated with <B> 32 </B> parts of chromium formate for some time at the boiling point. The solution is then evaporated and the dye is precipitated with common salt.
