Description
Verfahren zur Überführung von Küpenfarbstoffen der Anthraehinonreihe in besonders fein verteilte Form. Es wurde gefunden, dass man Küpen- farbstoffe der Anthrachinonreihe in beson ders fein verteilter Form in sehr einfacher Weise erhalten kann, wenn man die in wäs serigen Flüssigkeiten suspendierten Hydro- verbindungen der fraglichen Farbstoffe in Gegenwart von aussalzend wirkenden Kör pern, wie Kochsalz, Natriumsulfat, Kalium nitrat, Natronlauge usw. oxydiert.
Die Hydroverbindung geht direkt von ihrer festen Form in die feste Form des Farb stoffes über, worauf das so erhaltene Pro dukt wie üblich mechanisch zerkleinert wer den kann.
Beispiel 10 kg des Presskuchens der Hydro verbindung von N-Dihydro-1. 2 . 2' .1'-an- thrachinonazin werden in<B>300</B> kg 10 %ige Kochsalzlösung eingetragen und bei 50 bis <B>60'</B> unter Rühren durch Lufteinleiten aus oxydiert. Die Oxydation ist nach 1 bis 2 Stunden beendet. Nun wird durch eine Filterpresse gedrückt, nachgewaschen und schliesslich die so erhaltene Paste in einer Kugelmühle angerieben.
<I>Beispiel 2.-</I> <B>50</B> kg Flavanthrenpulver werden in 1000 kg einer annähernd gesättigten alko holischen Kochsalzlösung, welche zirka 40 kg Hydrosulfit enthält, eingetragen. Nach mehr stündigem Rühren bei 50 bis 60 ist die Umwandlung in die Hydroverbindung voll ständig, und es wird durch Lufteinleiten der Farbstoff regeneriert. Die Aufarbeitung ge schieht wie oben.
<I>Beispiel 3</I> 50 kg Indanthrengrün werden in 1000 Liter Wasser suspendiert und durch Zusatz der notwendigen Menge Natronlauge und Hydrosulfit in die Hydroverbindung ver wandelt. Nun fügt man Natriumsulfat zu, bis die Hydroverbindung völlig ausgesalzen ist, und bläst aus. Die Oxydation geht bei <B>60'</B> sehr rasch vor sich, die weitere Auf arbeitung geschieht wie im Beispiel 1.
Process for the transfer of vat dyes of the anthraehinone series in particularly finely divided form. It has been found that vat dyes of the anthraquinone series can be obtained in a particularly finely divided form in a very simple manner if the hydro compounds of the dyes in question suspended in aqueous liquids are in the presence of salting-out bodies, such as table salt, sodium sulfate , Potassium nitrate, caustic soda, etc. are oxidized.
The hydrocompound changes directly from its solid form to the solid form of the dye, whereupon the product thus obtained is mechanically crushed as usual.
Example 10 kg of the press cake of the hydro compound of N-dihydro-1. 2. 2 '.1'-anthrachinonazine are introduced into 300 kg of 10% sodium chloride solution and oxidized at 50 to 60 minutes by introducing air while stirring. The oxidation is over after 1 to 2 hours. Now it is pressed through a filter press, washed and finally the paste obtained in this way is rubbed in a ball mill.
<I> Example 2.- </I> <B> 50 </B> kg of flavanthrene powder are added to 1000 kg of an approximately saturated alcoholic common salt solution which contains approximately 40 kg of hydrosulfite. After more hours of stirring at 50 to 60, the conversion into the hydro-compound is complete and the dye is regenerated by introducing air. The processing is done as above.
<I> Example 3 </I> 50 kg of indanthrene green are suspended in 1000 liters of water and converted into the hydro-compound by adding the necessary amount of sodium hydroxide solution and hydrosulfite. Now add sodium sulphate until the hydro-compound is completely salted out and blow out. The oxidation takes place very quickly at <B> 60 '</B>, the further processing takes place as in example 1.
