Description

  

      Zusatzpatent    zum Hauptpatent Nr. 136649.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  wertvollen metallhaltigen Farbstoff erhält,  wenn man den     Azofa.rbstoff    aus.     diazotier-          ter        4-Chlor-2-amino-l-phenol-6-sulfosäure     und     2-Amino-8-oxynaphthalin-6-sulfosäure     mit kupferabgebenden Mitteln und mit einem  Oxydationsmittel behandelt, wobei diese bei  den Operationen nicht gleichzeitig, sondern  nacheinander durchgeführt werden.  



  Der erhaltene metallhaltige Farbstoff  bildet     ;getrocknet    ein graues Pulver, welches  in Wasser und in verdünnter     Sodalösung    mit       rötlichgrauer    und in     konzentrierter    Schwefel  säure mit graublauer Farbe löslich ist. Er  färbt     vegetabile    Fasern aus neutralem oder  alkalischem Bade in echten Grautönen an.

         Beispiel:     Man     kombiniert    in Gegenwart von Soda  223,5 Teile     dia.zotierte        4-Chlor-2-amino-l-          phenol-6-sulfosäure    mit 239 Teilen     2-Amino-          8-oxynaphthalin-6-sulfosäure    und führt den  Farbstoff     nach    bekannten Methoden in die    Kupferverbindung über. Diese wird in 8000  Teilen Wasser zusammen mit 50 Teilen Soda  zur Lösung gebracht und darauf mit der  105 Teilen. aktivem Chlor entsprechenden  Menge eines     Alkalihypchlorits    versetzt.

   Nach  einiger Zeit bildet sich aus dem     rotvioletten     Farbstoff ein neuer graufärbender, der im  Gegensatz zum     Ausgangsfarbstoff    Affinität  zur     vegetabilen    Faser zeigt. Durch Kochsalz       wird    er aus der Lösung abgeschieden und  durch     Umfällen        gereinigt.  



      Additional patent to main patent no. 136649. Process for the production of a new metal-containing dye. It has been found that a new valuable metal-containing dye is obtained by removing the azo-dye. diazotized 4-chloro-2-amino-1-phenol-6-sulfonic acid and 2-amino-8-oxynaphthalene-6-sulfonic acid treated with copper-releasing agents and with an oxidizing agent, these being carried out in the operations not simultaneously but one after the other will.



  The metal-containing dye obtained forms, when dried, a gray powder which is soluble in water and in dilute soda solution with a reddish-gray and in concentrated sulfuric acid with a gray-blue color. It stains vegetable fibers from neutral or alkaline bath in real shades of gray.

         Example: In the presence of soda, 223.5 parts of dia.zotierte 4-chloro-2-amino-1-phenol-6-sulfonic acid are combined with 239 parts of 2-amino-8-oxynaphthalene-6-sulfonic acid and the dye is carried out according to known methods Methods in the copper compound over. This is brought to a solution in 8000 parts of water together with 50 parts of soda and then with the 105 parts. active chlorine added amount of an alkali hypchlorite.

   After some time, the red-violet dye turns into a new gray color, which, in contrast to the original dye, shows an affinity for the vegetable fiber. It is separated from the solution by means of table salt and purified by reprecipitation.
