Description

  

  Zusatzpatent zum Hauptpatent Nr. 131098.    Verfahren zur Herstellung eines neuen metallhaltigen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Azofarbstoff    erhält, wenn man  den Farbstoff aus     diazotiertem        5-Nitro-2-          amino-l-phenol    und     2-Phenylamino-5-oxy-          naphthalin-7-sulfosäure    zunächst mit einem  Viertel der zur vollständigen     Metallisierung     notwendigen Menge eines kupferabgebenden  Mittels,

   alsdann mit einem weiteren Viertel  der zur vollständigen     Metallisierung    des     Azo-          farbstoffes    notwendigen Menge eines nickel  abgebenden Mittels und zuletzt bis zur Ab  sättigung der     metallisierbaren    Gruppen mit  chromabgebenden Mitteln weiter behandelt.  



  Der neue Farbstoff ist trocken ein     bron-          ziges,    dunkles Pulver, welches sich in Wasser,  Soda oder verdünnter Natronlauge mit rein  blauer, in konzentrierter Schwefelsäure mit  violetter Farbe löst und aus neutralem oder       sodaalkalischem,        glaubersalzhaltigen    Färbe  bad Baumwolle in reinen blauen Tönen färbt.    <I>Beispiel:</I>  Man löst den Farbstoff aus 15,4 Teilen         diazotiertem        5-Nitro-2-amino-l-phenol    und  31,5 Teilen     2-Phenylamino-5-oxynaphthalin-          7-sulfosäure    in 8000 Teilen heissem Wasser.

    Darauf gibt man nacheinander die gesättigten  Lösungen von 6,25 Teilen kristallisiertem  Kupfersulfat und 7 Teilen kristallisiertem  Nickelsulfat zu und erhitzt einige Minuten  zum Kochen unter Rühren. Dann gibt man  die wässerige Lösung von 15,6 Teilen     Crz0s     als 4     o/oiges        Fluorchtöm    zu und erwärmt  36 Stunden am     Rückfiusskühler.    Nach dieser  Zeit salzt man den Farbstoff heiss mit 200     gr     Kochsalz aus seiner Lösung aus und filtriert.



  Additional patent to main patent No. 131098. Process for the production of a new metal-containing azo dye. It has been found that a new metal-containing azo dye is obtained if the dye from diazotized 5-nitro-2-amino-1-phenol and 2-phenylamino-5-oxynaphthalene-7-sulfonic acid is initially mixed with a quarter of the total Metallization necessary amount of a copper releasing agent,

   then treated with a further quarter of the amount of a nickel-releasing agent necessary for complete metallization of the azo dye and finally treated further with chromium-releasing agents until the metallizable groups are saturated.



  The new dry dye is a bronzy, dark powder which dissolves in water, soda or dilute caustic soda with a pure blue color, in concentrated sulfuric acid with a violet color and dyes cotton in pure blue tones from a neutral or alkaline dye bath containing Glauber's salt. <I> Example: </I> The dye is dissolved from 15.4 parts of diazotized 5-nitro-2-amino-1-phenol and 31.5 parts of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid in 8000 parts of hot Water.

    The saturated solutions of 6.25 parts of crystallized copper sulfate and 7 parts of crystallized nickel sulfate are then added in succession and the mixture is heated to the boil for a few minutes while stirring. The aqueous solution of 15.6 parts of CrzOs is then added in the form of 4% fluorine content and the mixture is heated on a reflux condenser for 36 hours. After this time, the dyestuff is salted out of its solution while hot with 200 g of sodium chloride and filtered.

PATENTANSPRUCH: Verfahren zur Herstellung eines metall haltigen Azofarbstoffes, dadurch gekennzeich net, dass man den Farbstoff aus diazotiertem 5-Nitro-2-arnino-l-phenol und 2-Phenylamino- 5-oxynaphthalin-7-sulfosäure zunächst mit einem Viertel der zur vollständigen Metalli,- sierung notwendigen Menge eines kupfer abgebenden Mittels, PATENT CLAIM: Process for the production of a metal-containing azo dye, characterized in that the dye from diazotized 5-nitro-2-arnino-1-phenol and 2-phenylamino-5-oxynaphthalene-7-sulphonic acid is initially mixed with a quarter of the total Metallization necessary amount of a copper releasing agent, alsdann mit einem wei- teren Viertel der zur vollständigen Metalli- sierung des Azofarbstoffes-notwendigen Menge eines nickelabgebenden Mittels und zuletzt bis zur Absättigung der metallisierbaren Grup pen mit chromabgebenden Mitteln weiter behandelt. then treated with a further quarter of the amount of a nickel-releasing agent necessary for complete metallization of the azo dye, and finally with chromium-releasing agents until the metallizable groups are saturated. Der neue Farbstoff ist trocken ein bron- ziges, dunkles Pulver, welches sich in Wasser, Soda oder verdünnter Natronlauge mit rein blauer, in konzentrierter Schwefelsäure mit violetter Farbe löst und aus neutralem oder sodaalkälischem, glaubersalzhaltigen Färbebad Baumwolle in reinen blauen Tönen färbt. The new dye is a dry, bronzy, dark powder, which dissolves in water, soda or dilute caustic soda with a pure blue color, in concentrated sulfuric acid with a violet color and dyes cotton in pure blue tones from a neutral or soda-alkaline dye bath containing Glauber's salt.
