Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 200672.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man 1     Mol        2-(3'-          [4"-        Amino]    -     benzoylamino    -     5'-        amino)        -ben-          zoylamino-5-ogynaphthalin-7-sulfonsäure    mit  1     Mol        diazotierter        3.2'-Dimethyl-4-amino-          azobenzol-4'-sulfonsäure    vereinigt.

   Der so  erhaltene Farbstoff bildet ein braunes Pul  ver, das sich in Wasser mit roter Farbe löst  und Baumwolle in     violettroten    Tönen färbt,  die durch     Weiterdiazotieren    auf der Faser  und     Entwickeln    mit     ss-Naphthol    intensiv       braunrot    werden.  



       Beispiel:     305 Teile 3.     2'-Dimethyl-4-aminoazoben-          zol-4'-sulfonsäure    werden in üblicher     Weise          diazotiert.    Die mit verdünnter     Natriumcar-          bonatlösung    neutralisierte     Diazolösung    wird  in eine kalte Lösung aus 520     Teilen        2-(3'-          [4"    -     Amino]    -     benzoylamino,-    5' -     amino)    -     ben-          zoylamino-5-ogynaphthalin.-7-sulfonsäure,

  150       Teilen     Natriumcarbonat    und 20 000 Teilen  Wasser eingerührt. Nach beendeter Kupp  lung     wird    der Farbstoff     ausgesalzen,    ab  filtriert     und        getrocknet.  



  <B> Additional patent </B> to main patent no. 200672. Process for the production 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 - 5'-amino) - benzoylamino-5-ogynaphthalene-7-sulfonic acid with 1 mol diazotized 3.2'-dimethyl-4-amino-azobenzene-4'-sulfonic acid combined.

   The dye obtained in this way forms a brown powder which dissolves in water with a red color and dyes cotton in violet-red tones which are intensely brown-red when the fibers are further diazotized and developed with ss-naphthol.



       Example: 305 parts of 3. 2'-dimethyl-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-ogynaphthalene-7-sulfonic acid ,

  150 parts of sodium carbonate and 20,000 parts of water are stirred in. After coupling is complete, the dye is salted out, 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 - ogynaphthalin-7- sulfonsäure mit 1 Mol diazotierter 3. 2'-Di- methyl-4-aminoazobenzol-4'-sulfonsäure ver einigt. PATENT 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-ogynaphthalene-7-sulphonic acid is diazotized with 1 mol 3. 2'-Dimethyl-4-aminoazobenzene-4'-sulfonic acid united. Der so erhaltene Farbstoff bildet ein braunes Pulver, das sich in Wasser mit roter Farbe löst und Baumwolle in violettroten Tönen färbt, die durch Weiterdiazotieren auf der Faser und Entwickeln mit ss-Naphthol intensiv braunrot werden. The dye obtained in this way forms a brown powder which dissolves in water with a red color and dyes cotton in violet-red tones, which are intensely brown-red when the fibers are further diazotized and developed with ss-naphthol.
