Description

  

  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 290294.         Verfahren    zur     Herstellung        eines    kupferbaren     Azofarbstoffes.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines kupfer  baren     Azofarbstoffes,    welches darin besteht,    dass man 1     Mol    der     Aminomonoazoverbindung     der Zusammensetzung  
EMI0001.0009     
    und 1     Mol    der     Aminomonoazoverbindung    der Zusammensetzung  
EMI0001.0012     
    vorteilhaft in wässerigem Medium und in  Gegenwart eines säurebindenden Mittels, mit  1.

       Mol    eines     Fumarsäuredihalogenids    umsetzt.  



  Im nachfolgenden Beispiel bedeuten die  Teile Gewichtsteile.  



  <I>Beispiel:</I>  22,1 Teile der     Aminomonoazoverbindung     der Zusammensetzung (I) und 34,6 Teile der       Aminomonoazoverbindung    der Zusammenset  zung     (II)    werden zusammen in 2000 Teilen  Wasser mit Hilfe der dazu notwendigen Menge       Lithiumcarbonat    neutral gelöst. Man versetzt.

    die     Farbstofflösung    nach Zugabe von 30 Tei  len kristallisiertem     Natriumacetat    bei 8-12     unter gutem Rühren innerhalb von 5 bis 6  Stunden mit so viel einer Mischung aus 30  Teilen     Fumarsäuredichlorid    und 70 Teilen  Chlorbenzol, bis sich     in    der Reaktionslösung  keine freien     Aminogruppen    mehr nachweisen  lassen. Hierauf erwärmt man das Gemisch auf  90 , isoliert den gebildeten     Disazofarbstoff    auf  bekannte Weise, trocknet ihn und mahlt ihn.  



  Der neue kupferbare     Azofarbstoff    ist ein  dunkles Pulver, welches sich in Wasser und in       konzentrierter    Schwefelsäure mit roter Farbe  löst. Seine Ausfärbungen auf Baumwolle und  auf Fasern aus regenerierter     Cellulose,    die mit  kupferabgebenden Mitteln behandelt werden,  sind braun und besitzen ausgezeichnete Echt  heitseigenschaften.



  <B> Additional patent </B> to main patent no. 290294. Process for the production of a copperable azo dye. The subject of the present patent is a process for the preparation of a copper ble azo dye, which consists in that one mole of the aminomonoazo compound of the composition
EMI0001.0009
    and 1 mole of the amino monoazo compound of the composition
EMI0001.0012
    advantageously in an aqueous medium and in the presence of an acid-binding agent, with 1.

       Reacts mol of a fumaric acid dihalide.



  In the following example, the parts are parts by weight.



  <I> Example: </I> 22.1 parts of the aminomonoazo compound of the composition (I) and 34.6 parts of the aminomonoazo compound of the composition (II) are dissolved together in 2000 parts of water using the necessary amount of lithium carbonate. One transfers.

    the dye solution after adding 30 parts of crystallized sodium acetate at 8-12 with good stirring within 5 to 6 hours with enough of a mixture of 30 parts of fumaric acid dichloride and 70 parts of chlorobenzene until no free amino groups can be detected in the reaction solution. The mixture is then heated to 90 °, the disazo dye formed is isolated in a known manner, dried and ground.



  The new copperable azo dye is a dark powder that dissolves in water and in concentrated sulfuric acid with a red color. Its coloration on cotton and on fibers made of regenerated cellulose, which are treated with copper-releasing agents, are brown and have excellent authenticity properties.
