Description
Zusatzpatent zum Hauptpatent Nr. 141535. Verfahren zur Herstellung eines metallhaltigen Farbstores. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält wenn man den Farbstoff aus diazotiertem 4-Chlor-2- amino-l-phenol und Resorcin in einem Me dium, dessen Pti nicht grösser als 10 ist, mit einem Salz des dreiwertigen Eisens behan delt.
Der erhaltene Farbstoff stellt ein dunkel braunes Pulver dar, das sich in Natronlauge mit tiefbraunroter und in konzentrierter Schwefelsäure mit braungelber Farbe löst. Aus der braunen Lösung des Farbstoffes in Zaponlack erhält man auf Metallfolien braune Überzüge von guter Lichtechtheit. <I>Beispiel:</I> 2,63 Gewichtsteile des Farbstoffes aus diazotiertem 4-Chlor-2-amino-l-phenol und Resorcin werden in 200 Teilen Wasser ge löst und mit 4 Teilen Ferrioxalat unter Zu satz von 2/;s der äquivalenten Menge Na triumacetat einige Stunden zum Sieden er hitzt.
Die entstehende Eisenverbindung scheidet sich zum grössten Teile aus und wird nach dem Erkalten der Reaktions lösung durch Zugabe von etwas Kochsalz völlig abgeschieden.
Die Behandlung mit. Ferrioxalat führt zum gleichen Resultat, wenn man dem Reak tionsgemisch statt Natriumacetat andere Zu sätze, wie zum Beispiel Natriumformiat, Kochsalz oder Natriumsulfit, beigibt.
Additional patent to main patent no. 141535. Process for the production of a metal-containing stain. It has been found that a new metal-containing dye is obtained if the dye of diazotized 4-chloro-2-amino-1-phenol and resorcinol in a medium whose Pti is not greater than 10 is treated with a salt of trivalent iron delt.
The dye obtained is a dark brown powder which dissolves in sodium hydroxide solution with a deep brown-red color and in concentrated sulfuric acid with a brown-yellow color. Brown coatings of good lightfastness are obtained on metal foils from the brown solution of the dye in Zapon lacquer. <I> Example: </I> 2.63 parts by weight of the dye from diazotized 4-chloro-2-amino-1-phenol and resorcinol are dissolved in 200 parts of water and mixed with 4 parts of ferric oxalate with the addition of 2 / s The equivalent amount of sodium acetate is heated to the boil for a few hours.
The resulting iron compound separates out for the most part and is completely separated out after the reaction solution has cooled down by adding a little sodium chloride.
Treatment with. Ferrioxalate leads to the same result if other additives, such as sodium formate, common salt or sodium sulfite, are added to the reaction mixture instead of sodium acetate.
