Description

  

  Verfahren zur Herstellung eines wasserlöslichen, komplex gebundenes     Kupfer     enthaltenden     Farbstoffpräparates.       Es wurde gefunden, dass ein wasserlös  liches, komplex gebundenes Kupfer enthal-  
EMI0001.0003     
    ein kupferabgebendes     Mittel,    sowie     Diätha-          nolaminoessigsäure    aufeinander einwirken  lässt.  



  Das so erhaltene wasserlösliche, komplex  gebundenes Kupfer enthaltende Farbstoff  präparat stellt ein graues     Pulv    er dar, das in  Wasser löslich ist; demgegenüber ist die  komplexe Kupferverbindung, die aus dem  selben     Azofarbstoff    durch Behandeln mit  einem kupferabgebenden Mittel in Abwesen  heit von     Diäthanolaminoessigsäure          L\uOC2H4/2    -     N-CH2-COV11J            tendes        Farbstoffpräparat    erhalten werden  kann, wenn man den     Azofarbstoff    der  Formel    hergestellt wird, in Wasser unlöslich.

   Das       Farbstoffpräparat    eignet sich insbesondere  zum Färben von     zellulosehaltigem    Material,  wie zum Beispiel Baumwolle, Kunstseide aus  regenerierter Zellulose, Papier,     Kokosfaser     und Jute; beim     Färben.    wird aus     dem'Farb-          stoffpräparat        Diäthanolaminoessigsäure    ab  gespalten, und es werden sehr echte, insbe  sondere wasch- und lichtechte blaue Färbun  gen erhalten.  



  Das Verfahren kann beispielsweise der  art durchgeführt werden, dass man zuerst den       Azofarbstoff    obiger Formel mit dem kupfer-      abgebenden     Mittel    reagieren lässt und dann  auf die gebildete Kupferverbindung     Di-          äthanolaminoessigsäure    einwirken lässt.

           Beispiel:     10 Teile des     Natronsalzfarbstoffes    der  Formel  
EMI0002.0006     
    die als feuchtes     Pressgut    mit einem Wasser  gehalt von etwa<B>50%</B> vorliegen, werden mit  10 Teilen     :diäthanolaminoessigsaurem    Kupfer  der Formel       L(HOCZH4)2    -     N-CH,-COOI,,        Cu,   <B>11,0</B>  versetzt, das als Umsetzungsprodukt erhal  ten     wird,    wenn man :

  die 16 Teilen Kupfer  entsprechende Menge Kupferkarbonat mit  einer wässerigen Lösung von 8,5 Teilen     Di-          äthanolaminoessigsäure    (erhalten durch Ein-         wirkung    von 12 Teilen     Diäthanolamin    auf  die wässerige Lösung von 5 Teilen Chlor  essigsäure)     mischt.    Dann wird einige Zeit in  der     Knetmühle    verarbeitet und im Vakuum  zur Trockne verdampft.



  Process for the production of a water-soluble, complex-bound copper containing dye preparation. It has been found that a water-soluble, complex-bound copper contains
EMI0001.0003
    a copper-releasing agent and diethanolaminoacetic acid interact with each other.



  The water-soluble, complex-bound copper-containing dye preparation thus obtained is a gray powder which is soluble in water; In contrast, the complex copper compound, which can be obtained from the same azo dye by treatment with a copper donor in the absence of diethanolaminoacetic acid L \ uOC2H4 / 2 - N-CH2-COV11J tendes dye preparation when the azo dye of the formula is prepared in water insoluble.

   The dye preparation is particularly suitable for dyeing cellulose-containing material, such as cotton, rayon made from regenerated cellulose, paper, coconut fiber and jute; when dyeing. diethanolaminoacetic acid is cleaved from the dye preparation, and very real, especially washable and lightfast blue colorations are obtained.



  The method can be carried out, for example, by first allowing the azo dye of the above formula to react with the copper-releasing agent and then allowing diethanolaminoacetic acid to act on the copper compound formed.

           Example: 10 parts of the sodium salt dye of the formula
EMI0002.0006
    which are present as moist pressed material with a water content of about <B> 50% </B>, with 10 parts: diethanolaminoacetic acid copper of the formula L (HOCZH4) 2 - N-CH, -COOI ,, Cu, <B> 11 , 0 </B> added, which is obtained as a reaction product if you:

  the amount of copper carbonate corresponding to 16 parts of copper is mixed with an aqueous solution of 8.5 parts of diethanolaminoacetic acid (obtained by the action of 12 parts of diethanolamine on the aqueous solution of 5 parts of chloroacetic acid). Then it is processed in the kneading mill for some time and evaporated to dryness in a vacuum.

The water-soluble, complex-bound copper-containing dye preparation obtained in this way is a gray powder which is soluble in water; In contrast, the complex copper compound, which is produced from the same azo dye by treatment with a copper donor in the absence of diethanolaminoacetic acid, is insoluble in water. Das Farb- stoffpräparat eignet sich insbesondere zum Färben von zellulosehaltigem Material, wie zum Beispiel Baumwolle, Kunstseide aus regenerierter Zellulose, Papier, Kokosfaser und Jute; beim Färben wird aus dem Farb- stoffpräparat Diäthanolaminoessigsäure ab gespalten, und es werden sehr echte, ins besondere wasch- und lichtechte, blaue Fär bungen erhalten. The dye preparation is particularly suitable for dyeing cellulose-containing material, such as cotton, rayon made from regenerated cellulose, paper, coconut fiber and jute; During dyeing, diethanolaminoacetic acid is split off from the dye preparation, and very genuine, especially wash- and light-fast, blue dyeings are obtained. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man zuerst den Azofarb- stoff der Formel EMI0002.0039 mit dem kupferabgebenden Mittel zur Um setzung bringt und dann auf die entstandene Kupferverbindung Diäthanolaminoessigsäure einwirken lässt. SUBCLAIM: Process according to claim, characterized in that first the azo dye of the formula EMI0002.0039 with the copper-releasing agent to implement and then allows diethanolaminoacetic acid to act on the resulting copper compound.
