Description

  

      Zusatzpatent    zum Hauptpatent Nr. 145447.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden, dass man einen neuen  chromhaltigen     Farbstoff    erhält, wenn man  den     Azofarbstoff    aus     diazotiertem        4-Chlor-2-          amino-l-phenol    und     f-Naphthylamin    in Ge  genwart von     Pyridin    mit chromabgebenden  Mitteln behandelt.  



  Der erhaltene chromhaltige     Farbstoff    stellt  ein     grünschwärzes    Pulver dar, das sich in  Wasser oder Natronlauge nicht oder sehr  schwer und in     konz.    Schwefelsäure mit vio  letter Farbe löst. Aus der blaugrün gefärbten  Lösung des Farbstoffes in     Zaponlack    erhält  man auf Metallfolien blaugrüne Überzüge.

    <I>Beispiel:</I>  5,95 Gewichtsteile des Farbstoffes aus       diazotiertem        4-Chlor-2-amino-l-phenol    und       ss-Naphthylamin    werden in 250 Teilen     Pyri-          din    gelöst und mit 8 Teilen ameisensaurem  Chrom einige Stunden am     Rückflusskühler     zum Sieden erhitzt. Sobald die     Chromierung     beendet ist, filtriert man die tief blaustichig  grüne Lösung von Ungelöstem ab, destilliert  hierauf das     Pyridin    im Vakuum ab und  trocknet die     zurückbleibende    Chromverbin  dung bei mässiger Temperatur.

      Als chromabgebende Mittel können statt       Chromformiat    andere, wie z. B, Chromacetat,  verwendet werden ; die     Chrornieruiig    kann  ferner in Gegenwart geeigneter Zusätze, wie  z. B. der     Alkalisalze    organischer Säuren,  durchgeführt werden.



      Additional patent to main patent No. 145447. Process for the production of a new metal-containing dye. It has been found that a new chromium-containing dye is obtained if the azo dye consisting of diazotized 4-chloro-2-amino-1-phenol and f-naphthylamine is treated with chromium donating agents in the presence of pyridine.



  The chromium-containing dye obtained is a greenish-black powder which is difficult or impossible to dissolve in water or sodium hydroxide solution and in conc. Dissolves sulfuric acid with vio letter paint. Blue-green coatings are obtained on metal foils from the blue-green solution of the dye in Zapon varnish.

    <I> Example: </I> 5.95 parts by weight of the dye from diazotized 4-chloro-2-amino-1-phenol and β-naphthylamine are dissolved in 250 parts of pyridine and treated with 8 parts of chromium acid for a few hours on the reflux condenser heated to boiling. As soon as the chromation is complete, the deep blue-tinged green solution is filtered off from undissolved material, the pyridine is then distilled off in vacuo and the remaining chromium compound is dried at a moderate temperature.

      As a chromium donor, instead of chromium formate, other such. B, chromium acetate, can be used; the Chrornieruiig can also in the presence of suitable additives, such as. B. the alkali salts of organic acids are carried out.
