Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Azofarb-          stoffes,    dadurch gekennzeichnet, dass man       diazotiertes        1-Succinylamino-4-aminobenzol     mit     4-Methyl-l-oxybenzol    kuppelt.  



  Der als     Natriumsalz    isolierte Farbstoff  ist ein insbesondere nach Zusatz einer gerin  gen Menge     Natriumacetat    oder     Natriumcar-          bonat    in Wasser leicht lösliches, gelbes Pul  ver und färbt     Acetatseide    in klaren, grün  stichig gelben Tönen von sehr guter Licht  echtheit.  



  <I>Beispiel:</I>  20,8 Teile     1-Succinylamino-4-aminobenzol     werden     diazotiert.    Die erhaltene, nötigen  falls     diazotierte    Lösung lässt man in eine mit  überschüssigem     Natriumcarbonat    versetzte  Lösung von     1ä    Teilen des     Natriumsalzes    des       4-Methyl-l-oxybenzols    laufen. Der Farbstoff    wird durch Zugabe von Kochsalz ausgefällt,       abfiltriert    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 diazotized 1-succinylamino-4-aminobenzene is coupled with 4-methyl-1-oxybenzene.



  The dye, isolated as the sodium salt, is a yellow powder that is readily soluble in water, especially after the addition of a small amount of sodium acetate or sodium carbonate, and dyes acetate silk in clear, green-tinged yellow shades of very good lightfastness.



  <I> Example: </I> 20.8 parts of 1-succinylamino-4-aminobenzene are diazotized. The resulting, necessary if diazotized solution is allowed to run into a solution of 1ä parts of the sodium salt of 4-methyl-1-oxybenzene to which excess sodium carbonate has been added. The dye is precipitated by adding sodium chloride, filtered off and dried.
