Description

  

  Verfuhren zur Herstellung eines     Monoazofarbstoifes.       Gegenstand     des    vorliegenden Zusatz  patentes ist ein Verfahren zur Herstellung  eines     Monoazofarbstoffes,    welches dadurch  gekennzeichnet ist, dass man die     Diazo-          verbindung    von 1-     Amino    -     2,5    -     diäthoxy    -     4-          benzoylaminobenzol    mit     2,

  3-Oxynaphthoyl-          l'        -aminobenzol-        2(-        (sulf        onyl-n-        dibutylamin)     kuppelt.  



  <I>Beispiel:</I>  15 Gewichtsteile     1-Amino-2,5-diäthoxy-          4-benzoylaminobenzol        werden    in der     üblichen     Weise     diazotiert.    Hierauf versetzt man die       Diazolösung    zur Bindung der     überschüssigen     Mineralsäure mit     Natriumacetat    und rührt  sie in eine Lösung von 22,7 Gewichtsteilen  2,3 -     Oxynaphthoyl    -     l'-        aminobenzol    - 2'-     (sul-          fonyl-n-dibutyla.min)    in verdünnter Natron  lauge ein.

   Nach Beendigung der Kupplung  wird der entstandene Farbstoff     abfiltriert,     gut ausgewaschen und getrocknet.  



  Er stellt ein blauviolettes Pulver dar, das    sich in     Butylalkohol,        Xylol    und andern or  ganischen     Lösungsmitteln    leicht löst und       Celluloseesterlacke    in violetten Tönen von  guten Echtheitseigenschaften färbt.



  Process for the production of a monoazo dye. The subject of the present additional patent is a process for the production of a monoazo dye, which is characterized in that the diazo compound of 1- amino - 2,5 - diethoxy - 4 - benzoylaminobenzene with 2,

  3-Oxynaphthoyl- l'-aminobenzene-2 (- (sulfonyl-n-dibutylamine) couples.



  <I> Example: </I> 15 parts by weight of 1-amino-2,5-diethoxy-4-benzoylaminobenzene are diazotized in the usual way. Sodium acetate is then added to the diazo solution to bind the excess mineral acid and it is stirred into a solution of 22.7 parts by weight of 2,3-oxynaphthoyl-l'-aminobenzene-2'- (sulphonyl-n-dibutyla.min) in dilute Soda lye.

   After the coupling has ended, the resulting dye is filtered off, washed well and dried.



  It is a blue-violet powder that dissolves easily in butyl alcohol, xylene and other organic solvents and colors cellulose ester coatings in violet shades with good fastness properties.

PATENTANSPRUCH: Verfahren zur Herstellung eines Mono- azofarbstoffes, dadurch gekennzeichnet, dass man die Diazoverbindung von 1-Amino-2,5- diäthoxy-4-benzoylaminobenzol mit 2,3-Oxy naphthoyl-l'-aminobenzol-2'-(.sulfonyl-n-di- butylamin) kuppelt. Claim: Process for the preparation of a monoazo dye, characterized in that the diazo compound of 1-amino-2,5-diethoxy-4-benzoylaminobenzene with 2,3-oxynaphthoyl-l'-aminobenzene-2 '- (. Sulfonyl -n-di-butylamine) couples. Der erhaltene Farbstoff stellt ein blau violettes Pulver dar, das sich in Butylalko- hol, Xylol und andern organischen Lösungs mitteln leicht löst und Celluloseesterlacke in violetten Tönen von guten Echtheitseigen schaften färbt. The dye obtained is a blue-violet powder which dissolves easily in butyl alcohol, xylene and other organic solvents and colors cellulose ester lacquers in violet shades with good fastness properties.
