Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 110287.         Verfahren    zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen  neuen     Farbstoff    erhält, wenn man die     dia-          zotierte        3-Aminonaphthalin-1,8-dikarbonsäure          finit    1-     (4'-Oxy-3'-karboxyl)        -phenyl-5-pyrazo-          lon-3-karbonsäure    kuppelt. Der neue     Farb-          stoff    bildet ein rotes Pulver, das sich in  Wasser mit orangegelber, in Schwefelsäure  mit roter Farbe löst.

   Er färbt Wolle aus  saurem Bade in rotgelben Tönen, welche beim       Nachchromieren    grüngelb und sehr echt, ins  besondere     pottingecht    werden. Im Chrom  druck erzeugt er echte,     rötlichgelbe    Töne.

      <I>Beispiel:</I>    10,6 Teile     3-Arninonaphthaliii-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10       Teilen        30        %        iger        Natronlauge        und        150        Tei-          len    Wasser heiss gelöst,

   nach Abkühlung auf  zirka 200 mit 80 Teilen Eis und 25 Teilen       30        %        iger        Salzsäure        versetzt.        Es        scheidet     sich die     3-Aminonaphthaliii-1,8-dikarbonsäure     aus, welche auf Zusatz von 3,5 Teilen Ni  trit zunächst in Lösung geht, um bald wie  der als     Diazoverbindung    auszufallen. Die so    erhaltene Suspension wird in eine alkalische  Lösung von 13,2 Teilen 1-     (4'-Oxy-3'-karbo-          xyl)        -phenyl-5-pyrazolon-3-karbonsäure    einlau  fen gelassen.

   Nach beendeter Kupplung wird  das überschüssige Alkali mit Säure abge  stumpft, der     Farbstoff        ausgesalzen,    filtriert  und getrocknet.



  <B> Additional patent </B> to main patent no. 110287. Process for the production of a new dye. It has been found that a new dye is obtained if the diazotized 3-aminonaphthalene-1,8-dicarboxylic acid finitely 1- (4'-oxy-3'-carboxyl) -phenyl-5-pyrazolone-3 -carboxylic acid couples. The new dye forms a red powder that dissolves in water with an orange-yellow color and in sulfuric acid with a red color.

   It dyes wool from an acid bath in red-yellow tones, which when chromium-plating turn green-yellow and very real, especially potting-proof. With chrome printing, it creates real, reddish yellow tones.

      <I> Example: </I> 10.6 parts of 3-aminonaphthaliii-1,8-dicarboxylic acid anhydride are dissolved hot with the aid of 10 parts of 30% sodium hydroxide solution and 150 parts of water,

   after cooling to about 200, 80 parts of ice and 25 parts of 30% hydrochloric acid are added. The 3-aminonaphthaliii-1,8-dicarboxylic acid separates out, which upon the addition of 3.5 parts of Ni trite initially goes into solution and soon precipitates as the diazo compound. The suspension thus obtained is allowed to run into an alkaline solution of 13.2 parts of 1- (4'-oxy-3'-carboxylic xyl) phenyl-5-pyrazolone-3-carboxylic acid.

   After the coupling has ended, the excess alkali is blunted with acid, the dye is salted out, filtered and dried.

PATENTANSPRUCH Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man die diazötierte 3-Aminonaphthalin-1,8- dikarbonsäure mit 1- (4'-Oxy-3'-karboxyl)-- phenyl- ,5-pyrazolon - 3-karbonsäure kuppelt. Der neue Farbstoff bildet ein rotes Pulver, das sich in Wasser mit orangegelber, in Schwefelsäure mit roter Farbe löst. Er färbt Wolle aus saurem Bade in rotgelben Tönen, welche beim Nachchroinieren grüngelb und sehr echt, insbesondere pottingecht werden. PATENT CLAIM Process for the production of a new dye, characterized in that the diazotized 3-aminonaphthalene-1,8-dicarboxylic acid is mixed with 1- (4'-oxy-3'-carboxyl) phenyl, 5-pyrazolone 3-carboxylic acid clutch. The new dye forms a red powder that dissolves in water with an orange-yellow color and in sulfuric acid with a red color. It dyes wool from an acid bath in red-yellow tones, which when re-chroined become green-yellow and very real, especially potting-proof. Im Chromdruck erzeugt er echte, rötlich gelbe Töne. In chrome printing, it creates real, reddish yellow tones.
