Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 261125.    Verfahren zur Herstellung eines kupferbaren     Polyazofarbstoffes.       Gegenstand vorliegenden     Patentes    ist ein  Verfahren zur Herstellung eines kupferbaren       Polyazofarbstoffes.    Das Verfahren ist da  durch gekennzeichnet, dass man 1     Mol    der       Tetrazoverbindung    von     1-(3'-Amino-4'-oxy-          benzoylamino)-4-amino-benzol    einerseits mit  1     Mol        2-Oxy-4-methyl-benzol-carbonsäure    uni  anderseits mit 1     Mol        1-(4'-Amino-phenyl)        :

  3-          phenyl-5-pyx-azolon    kuppelt.    Der erhaltene neue     Disazofarbstoff    stellt  ein dunkelbraunes Pulver dar, welches sieh in  Wasser mit gelber und in     konz.    Schwefel  säure mit gelbbrauner Farbe löst.

   Er färbt  Fasern aus Baumwolle und Zellwolle nach  gekupfert in gelbbraunen Tönen von sehr  guten     Echtheiten.       <I>Beispiel,:</I>  24,3 Teile 1- (3' -     Amino    - 4' -     oxy    -     benzoyl-          amino)-4-amino-benzol    werden in salzsaurer  Lösung mit 13,8 Teilen     Natriumnitrit    in der  Kälte     tetrazotiert,    die überschüssige Mineral  säure mit Soda abgestumpft und mit, einer       wässrigen        minosaalkalischen        Lösung    von 15,

  2  Teilen     2-Oxy-4-methyl-benzolcarbonsäure    in  Gegenwart von 8 Teilen Natronlauge bei ge  wöhnlicher Temperatur zum     Zwischenprodukt     vereinigt. Nach 24 Stunden ist die Zwischen  produktbildung beendet, und man     lä.sst    bei  gewöhnlicher Temperatur 25,1 Teile 1-(4'  Amino-phenyl)-3-phenyl-5-pz-razolon, gelöst  in 200 Teilen Wasser, in Gegenwart von 10  Teilen Soda zufliessen. Der fertig gebildete  Farbstoff von der Formel  
EMI0001.0029     
    wird mit Kochsalz abgeschieden,     abfiltriert    und getrocknet.



  <B> Additional patent </B> to main patent no. 261125. Process for the production of a copperable polyazo dye. The present patent relates to a process for the preparation of a copperable polyazo dye. The process is characterized in that 1 mol of the tetrazo compound of 1- (3'-amino-4'-oxy-benzoylamino) -4-aminobenzene is mixed with 1 mol of 2-oxy-4-methyl-benzene-carboxylic acid uni on the other hand with 1 mol of 1- (4'-aminophenyl):

  3- phenyl-5-pyx-azolone couples. The new disazo dye obtained is a dark brown powder, which looks yellow in water and in conc. Sulfuric acid dissolves with a yellow-brown color.

   After coppering, it dyes fibers made of cotton and rayon in yellow-brown shades of very good fastness properties. <I> Example: </I> 24.3 parts of 1- (3 '- amino - 4' - oxy - benzoylamino) -4-aminobenzene are mixed with 13.8 parts of sodium nitrite in a hydrochloric acid solution in the cold tetrazotized, the excess mineral acid blunted with soda and with, an aqueous minosa-alkaline solution of 15,

  2 parts of 2-oxy-4-methyl-benzenecarboxylic acid combined in the presence of 8 parts of sodium hydroxide solution at ordinary temperature to give the intermediate product. After 24 hours, the formation of the intermediate product has ended, and 25.1 parts of 1- (4 'aminophenyl) -3-phenyl-5-pz-razolone, dissolved in 200 parts of water, are left at ordinary temperature in the presence of Add 10 parts of soda. The finished dye of the formula
EMI0001.0029
    is precipitated with common salt, filtered off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines kupfer baren Polyazofarbstoffes, dadurch gekenn zeichnet, dass man 1 Mol der Tetrazoverbin- dung von 1-(3'-Amino-4'-oxy-benzoylamino)- 4-amino-benzol einerseits mit 1 Mol 2-Oxy-4- methyl-benzöl-carbonsäure und anderseits mit 1 112o1 1- (4'-Amino-pheny 1) -3-phenyl-5-pyr- azolon kuppelt. PATENT CLAIM: Process for the production of a copper-free polyazo dye, characterized in that 1 mol of the tetrazo compound of 1- (3'-amino-4'-oxy-benzoylamino) -4-amino-benzene is mixed with 1 mol of 2- Oxy-4-methyl-benzo-oil-carboxylic acid and on the other hand with 1112o1 1- (4'-aminopheny 1) -3-phenyl-5-pyrazolone coupled. Der erhaltene neue Disazofarbstoff stellt ein dunkelbraunes Pulver dar, welches sich in Wasser mit gelber und in konz. Schwefel säure mit gelbbrauner Farbe löst. Er färbt Fasern aus Baumwolle und Zellwolle nach gekupfert in gelbbraunen Tönen von sehr guten Echtheiten. The new disazo dye obtained is a dark brown powder, which turns yellow in water and in conc. Sulfuric acid dissolves with a yellow-brown color. After coppering, it dyes fibers made of cotton and rayon in yellow-brown shades of very good fastness properties.
