Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 200672.    Verfahren zur     Ilerstelluu;    eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man 1     Mol    2-(3'  [4" -     Amino]    -     benzoylamino,-        ä'-        amino)        -ben-          zoylamino-5-ogynaphthalin-7-sulfonsäure    mit  1     Mol        diazotierter        4-Aminoazobenzol-4'-sul-          fonsäure    vereinigt.

   Der so erhaltene Farb  stoff bildet ein     bronzefarbiges    Pulver, das  sich in Wasser mit roter Farbe löst und  Baumwolle in     blaustichigroten    Tönen färbt,  die durch     Weiterdiazotieren    auf der Faser  und Entwickeln mit     ss-Naphthol    intensiv rot  werden.  



       Beispiel:     277 Teile 4 -     Aminoazobenzol    - 4'-     sulfon-          säure    werden in üblicher Weise     diazotiert.     Die mit verdünnter     Natriumcarbonatlösung     neutralisierte     Diazolösung    wird     in    eine kalte  Lösung aus 520 Teilen     2-(3'-[4"-Amino]-          benzoylamino-5'-        amino)-benzoylamino-5-oxy-          naphthalin-7-sulfonsäure,    150 Teilen Na-         triumcarbonat    und 20 000 Teilen Wasser ein  gerührt.

   Nach beendeter Kupplung wird der  Farbstoff, gegebenenfalls nach Zusatz von  Kochsalz,     abfiltriert    und getrocknet.



  <B> Additional patent </B> to main patent no. 200672. Process for Ilerstelluu; of a new azo dye. It has been found that a new azo dye is obtained if 1 mol of 2- (3 '[4 "- amino] - benzoylamino, - ä'-amino) -benzoylamino-5-ogynaphthalene-7-sulfonic acid with 1 mol diazotized 4-aminoazobenzene-4'-sulphonic acid combined.

   The dye obtained in this way forms a bronze-colored powder which dissolves in water with a red color and dyes cotton in bluish-tinted red tones which become intense red when the fibers are further diazotized and developed with ss-naphthol.



       Example: 277 parts of 4-aminoazobenzene-4'-sulfonic acid are diazotized in the usual way. The diazo solution, neutralized with dilute sodium carbonate solution, is poured into a cold solution of 520 parts of 2- (3 '- [4 "-amino] - benzoylamino-5'-amino) benzoylamino-5-oxynaphthalene-7-sulfonic acid, 150 parts of Na - Trium carbonate and 20,000 parts of water are stirred.

   After the coupling has ended, the dye, if appropriate after addition of common salt, is filtered off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man 1 Mol 2-(3'-[4"-Amino]-benzoylamino- 5'-amino) -benzoylamino - 5 - oxynaphthalin - 7- sulfonsäure mit 1 Mol diazotierter 4-Amino- azobenzol-4'-sulfonsäure vereinigt. Claim: Process for the preparation of a new azo dye, characterized in that 1 mol of 2- (3 '- [4 "-amino] -benzoylamino-5'-amino) -benzoylamino-5-oxynaphthalene-7-sulfonic acid is mixed with 1 mol of diazotized 4-Amino-azobenzene-4'-sulfonic acid combined. Der so erhaltene Farbstoff bildet ein bronzefarbiges Pulver, das sich in Wasser mit roter Farbe löst und Baumwolle in blaustichigroten Tönen färbt, die durch Weiterdiazotieren auf der Faser und Entwickeln mit ss-Naphthol intensiv rot werden. The dye thus obtained forms a bronze-colored powder which dissolves in water with a red color and dyes cotton in bluish-tinged red tones, which become intensely red when the fibers are further diazotized and developed with ss-naphthol.
