Description

  

      Zusatzpatent    zum Hauptpatent Nr. 131099.    Verfahren zur Herstellung eines metallhaltigen     Azofarustoffes.       Es wurde gefunden, dass man     einen    neuen       wertvollen,    metallhaltigen     Azofarbstoff    er  hält, wenn man den Farbstoff .aus     diazo-          tierter        2-Amino-l-oxynaphthalin-4,8-idisulfo-          säure    und     ,ss-Naphthol    mit den Produkten,       welche    aus     Kobaltsalzen    und Glyzerin in  Gegenwart von     Xtzalkalien    entstehen, be  handelt.  



  Der     kohalthaltige    Farbstoff stellt ge  trocknet ein .schwach bronzierendes, braun  violettes Pulver dar, welches in Wasser mit  violetter Farbe, in     1(1        %iger    Natronlauge  ohne Farbänderung und in konzentrierter  Schwefelsäure     blauviolett    löslich ist. Im       essigsauren    Färbebad werden Wolle und  Seide in     rotvioletten    Tönen von guten Echt  heiten     angef        ärbt.     



       Beispiel:     13 Teile     Kobaltchlorür    werden in 200  Teilen Wasser gelöst und mit 10 Teilen  Glyzerin versetzt, alsdann eine     Lösung    von  15 Teilen     Ätzkali    in 15 Teilen Wasser und    dann 55 Teile einer 43     %igen        Farbstoffpaste     (=     '/2o        Mol.)    des Farbstoffes aus     diazotier-          ter        2-Amino-l-oxynaphthalin-4,@8-disulfo-          säure    und     :ss-Naphthol    zugefügt.

   Nach sechs  stündigem Kochen am     Rückflusskühler        wird     noch eine Lösung von 25     Teilen        Ätzkali    in  25 Teilen Wasser zugegeben und weitere 15  Stunden gekocht. Dann wird auf 500 Teile  verdünnt,     filtriert,    mit Essigsäure neutral  gestellt und aasgesalzen. Die     Kobaltverbin-          ,dung    (des Farbstoffes scheidet sich kristalli  nisch aus.



      Additional patent to main patent no. 131099. Process for the production of a metal-containing azo-fragrant substance. It has been found that a new, valuable, metal-containing azo dye is obtained if the dye is made from diazotized 2-amino-1-oxynaphthalene-4,8-idisulphonic acid and β-naphthol with the products from Cobalt salts and glycerine are formed in the presence of Xtzalkalien.



  When dried, the carbon-containing dye is a weakly bronzing, brown-violet powder, which is blue-violet in water with a violet color, in 1% sodium hydroxide solution and in concentrated sulfuric acid. In the acetic acid dye bath, wool and silk turn red-violet tones stained by good authenticity.



       Example: 13 parts of cobalt chloride are dissolved in 200 parts of water and 10 parts of glycerine are added, then a solution of 15 parts of caustic potash in 15 parts of water and then 55 parts of a 43% dye paste (= 1/2 mol.) Of the diazotized dye - ter 2-amino-1-oxynaphthalene-4, @ 8-disulfonic acid and: ß-naphthol added.

   After boiling for six hours on the reflux condenser, a solution of 25 parts of caustic potash in 25 parts of water is added and the mixture is boiled for a further 15 hours. Then it is diluted to 500 parts, filtered, neutralized with acetic acid and carrion salted. The cobalt compound (of the dye separates out crystalline.

PATENTANSPRUCH: Verfahren zur Herstellung eines kobalt- haltigen Farbstoffes, dadurch gekennzeich net, dass man den Farbstoff aus diazotierter 2-Amino-l,-oxynaphthalin - 4;8 - ,disulfosäure und ss-Naphthol mit den Produkten, welche aus Kobaltsalzen und Glyzerin in Gegen wart von Ätzalkalien entstehen, behandelt. PATENT CLAIM: Process for the production of a cobalt-containing dye, characterized in that the dye from diazotized 2-amino-l, -oxynaphthalene - 4; 8 -, disulfonic acid and β-naphthol with the products, which are made from cobalt salts and glycerine in In the presence of caustic alkalis, treated. Der kobalth.altige Farbstoff stellt ge trocknet ein schwach bronzierendes, braun- violettes Pulver dar, welches in Wasser mit violetter Farbe, in 10 %iger Natronlauge ohne Farbänderung und in konzentrierter Schwefelsäure blauviolett löslich ist. Im essigsauren Färbebad werden Wolle und Seide in rotvioletten Tönen von guten Echt- heiten angefärbt. When dried, the cobalt-containing dye is a slightly bronzing, brown-violet powder, which is soluble in water with a violet color, in 10% sodium hydroxide solution without any change in color, and in concentrated sulfuric acid, blue-violet. In the acetic acid dye bath, wool and silk are dyed in red-violet shades of good fastness.
