Description
Zusatzpatent zum Hauptpatent Nr. 141535. Verfahren zur Herstellung eines metallhaltigen Färbstoffes. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält, wenn man den Farbstoff aus diazotiertem 4-Chlor-2- amino-l-phenol und 1-Pheiiyl-3-methyl-5-pyi,- azolon mit der Suspension einer Verbindung des dreiwertigen Eisens behandelt.
Der gebildete Farbstoff stellt ein olive- braunes Pulver dar, das in Wasser sehr schwer, in Natronlauge etwas mit braun gelber und in konzentrierter Schwefelsäure mit braunroter Farbe löslich ist. Aus der grünstichig gelben Lösung in Zapon- und andern Lacken erhält man auf Metallfolien gut lichtechte, grünstichig gelbe Anstriche.
<I>Beispiel:</I> <B>6,57</B> Teile des Farbstoffes aus diazotier- tem 4-Chlor-2-amino-l-phenol und 1-Phenyl- 3-methyl-5-pyrazolon werden in<B>500</B> Teilen Wasser aufgekocht und mit einer Aufschlärn- mung von frisch gefälltem Ferrihyclroxyd, entsprechend 1,2 Teilen Eisen, einige Zeit am Rückflusskühler zum Sieden erhitzt. Nach dem Erkalten wird der ausgeschiedene Farb- stoff abfiltriert, ausgewaschen und bei mässiger Temperatur getrocknet.
Additional patent to main patent no. 141535. Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye of diazotized 4-chloro-2-amino-1-phenol and 1-phenyl-3-methyl-5-pyi, - azolone with the suspension of a compound of treated with trivalent iron.
The dye formed is an olive-brown powder which is very difficult to dissolve in water, somewhat brownish-yellow in sodium hydroxide solution, and brownish-red in concentrated sulfuric acid. The greenish yellow solution in Zapon and other lacquers gives good lightfast, greenish yellow paints on metal foils.
<I> Example: </I> <B> 6.57 </B> parts of the dye are made from diazotized 4-chloro-2-amino-1-phenol and 1-phenyl-3-methyl-5-pyrazolone Boiled in <B> 500 </B> parts of water and heated to boiling for some time on a reflux condenser with a suspension of freshly precipitated ferric hydroxide, corresponding to 1.2 parts of iron. After cooling, the precipitated dye is filtered off, washed out and dried at a moderate temperature.
