  Verfahren zur Herstellung eines     substantiven        Trisazofarbstoffes.            Vorliegendes        Patent    betrifft ein     Verf        ah-          ren    zur Herstellung eines     substantiven        Tris-          azofarbstoffes.    Das Verfahren ist dadurch  gekennzeichnet, dass man     diazoti#erte        2-          Aminonaphthalin-4,8-,disulfonsäure    mit 1  Amino-3-methylbenzol kuppelt,

   den     Amino-          monoazofarbstoff    weiter     diazotiert,    mit     1-          Amino-3-methyl-6-methogybenzol    vereinigt,  den     Aminodisazofarbstoff    mit     4-Nitroben-          zoylchllorid        umsetot,        die    Nitrogruppe zur       Aminogruppe        reduziert    und     schliesslich    den  so erhaltenen     aminobenzoylieTten        Di:

  saz-ofarb-          stoff        dianotiert    und. mit     1-(3'-Aminoplienyl)-          5-pyrazolon-3-c-arbon:säure    kuppelt.  



  Der neue Farbstoff löst sich in     Wasser     mit     roto:ranger    Farbe und ergibt auf Baum  wolle     rotstichig    orange Färbungen, die sich  in üblicher Weise zu gut neutral und alka  lisch     ätzbaren        rotstichigen        Orangetönen    von       sehr    guter Licht- und     Waschechthieit    ent  wickeln lassen.

      <I>Beispiel:</I>  30 Teils     2-Aminonaphthalin-4,8-disulfon-          säure    werden in bekannter     Weise    mit 7 Tei  len     Natriumnitrit        und,   <B>98</B> Teilen     Salzsäure     (19,5       B6)

          diazotiert        und    in     essigsaurer    Lö  sung mit 11 Teilen     1-Amino-3-methylbenzol          gekuppelt.    Nach     Beendigung    der Kupplung  wird     der    Farbstoff in     Natronlauge    gelöst  und mit 8 Teilen     Natriumnitrit    und 3,

  5 Teilen  Salzsäure     weiterdiazotiert    und nun an zwei  ter     Stelle    mit 14     Teilen        1-Amino-3-methyl-6-          methogybenzol        dureh    Zugabe von     Sodalösun.g     in     schiwach        saurem.        Medium    gekuppelt.

   Nach  der     Isolierung    des     Disazofarbs@to-ffes        lässt          mann    zu der auf<B>70'</B> C     ..gehaltenen    neutralen  Lösung des Farbstoffes 18 Teile in wenig  Benzol     gelöstes;

          4-Nitrobenzoylchlorid    unter  gleichzeitiger Zugabe von     Sada        zulaufen,     wobei darauf zu achten ist,     dass    die     Reaktion     ungefähr     neutral,    bleibt.     Wenn        eine    heraus  genommene Probe sich     niclirt    mehr     diazotieren          lässt,    werden 36- Teile     Natriumsulfid;        krist.         zugegeben; die     Reduktion    tritt     sofort    ein;

    das Reduktionsprodukt wird mit wenig  Kochsalz isoliert. Die so erhaltene Paste des       aminobenzoy        lierten        Disazofarbstoffes        wird    in       heissem    Wasser gelöst, auf Eis und 30 Teile  Salzsäure laufen lassen und mit etwa 7 Tei  len     Natriumnitrit        d.iazotiert;    die     Diazotie-          rung        ist    nach etwa ?-3 Stunden beendet.

    Zum Schluss wird mit 19.5 Teilen     1-(3'-          Aminophenyl)-5-pyrazolon-3-oarbonsäure,    am  besten bei schwach saurer     Reaktion,    gekup  pelt. Der Farbstoff wird nach Beendigung  der Kupplung alkalisch isoliert. Der neue  Farbstoff stellt ein ziegelrotes Pulver dar,  das sich in Wasser mit     rotoranger        Farbe     löst.

   Er ergibt auf Baumwolle     rotstichig          orange    Färbungen. die sich auf der Faser  mit     diazot.iertem        1-Amnino-4-niti-obenzol          beziv.    nach dem     Diazotieren    mit     2-Oxy-          naphthal:in    oder     l.-Phenyl-3-nietliyl-5-pyra-          zolon    zu gut neutral und alkalisch     ätzbaren          rotstichigen        Orangetönen    von sehr     guter     Licht- und     Wasebechtlieit    entwickeln lassen.



  Process for the preparation of a substantive trisazo dye. The present patent relates to a process for the production of a substantive trisazo dye. The process is characterized in that diazotized 2- aminonaphthalene-4,8-, disulfonic acid is coupled with 1 amino-3-methylbenzene,

   the amino monoazo dye is further diazotized, combined with 1-amino-3-methyl-6-methogybenzene, the amino disazo dye reacted with 4-nitrobenzoyl chloride, the nitro group is reduced to the amino group and finally the aminobenzoylieTten Di thus obtained:

  saz-ofarbstoff dianotiert and. with 1- (3'-aminoplienyl) -5-pyrazolon-3-c-carbon: acid coupling.



  The new dye dissolves in water with roto: ranger color and produces reddish-tinged orange colorations on cotton, which can be developed in the usual way into neutral and alkaline-etchable red-tinged orange tones with very good lightfastness and washfastness.

      <I> Example: </I> 30 parts of 2-aminonaphthalene-4,8-disulphonic acid are mixed in a known manner with 7 parts of sodium nitrite and <B> 98 </B> parts of hydrochloric acid (19.5 B6)

          diazotized and coupled in acetic acid solution with 11 parts of 1-amino-3-methylbenzene. After the coupling has ended, the dye is dissolved in sodium hydroxide solution and treated with 8 parts of sodium nitrite and 3,

  5 parts of hydrochloric acid further diazotized and now in the second place with 14 parts of 1-amino-3-methyl-6-methogybenzene by adding Sodalösun.g in weakly acidic. Medium coupled.

   After the isolation of the disazo dye @ to-ffes, 18 parts of dissolved in a little benzene are added to the neutral solution of the dye kept at <B> 70 '</B> C.

          Run in 4-nitrobenzoyl chloride while adding Sada, making sure that the reaction remains approximately neutral. If a sample taken out can no longer be diazotized, 36 parts of sodium sulphide become; Krist. admitted; the reduction occurs immediately;

    the reduction product is isolated with a little common salt. The resulting paste of the aminobenzoy lated disazo dye is dissolved in hot water, run on ice and 30 parts of hydrochloric acid and diazotized with about 7 parts of sodium nitrite; the diazotization is over after about -3 hours.

    Finally, 19.5 parts of 1- (3'-aminophenyl) -5-pyrazolon-3-carboxylic acid are coupled, preferably with a weakly acidic reaction. After the coupling has ended, the dye is isolated under alkaline conditions. The new dye is a brick-red powder that dissolves in water with a red-orange color.

   It produces reddish-tinged orange colorations on cotton. which are on the fiber with diazotized 1-Amnino-4-niti-obenziv beziv. After diazotizing with 2-oxynaphthalene, let develop in or 1- phenyl-3-nietliyl-5-pyrazolone into red-tinged orange tones that can be easily etched neutral and alkaline and are very light and water-fast.
