Description
Zusatzpatent zum Hauptpatent Nr.<B>257722.</B> Verfahren zur Herstellung eines Küpenfarbatoffes. Es wurde gefunden, dass ein wertvoller Küpenfarbstoff hergestellt werden kann, wenn man das Kondensationsprodukt aus 1 Mol 3',6'-1)ihalogen-3,4-phthaloyl-pyren und 2 Mol 4-Amino-7,1'-diantliriinid mit Sulfurylchlorid unter Jodzusatz bei 60 bis 700 chloriert und dann mit earbazolierenden Mitteln behandelt.
Der neue Farbstoff ist ein schwarzes Pul ver, das sich in konz. Schwefelsäure mit sehwarzbrauner Farbe löst und Baumwolle aus brauner Küpe in olivgrauen Tönen färbt.
Beisniel: Das durch Kondensation in trockenem Ni- trobenzol aus 1 Mol 3',6'-Dihalogen-3,4-phtha- loyl-pyren und 2 Mol 4-Amino-1,1'-dianthrimid unter Zusatz von Kupferacetat erhaltene Re aktionsprodukt wird ohne zu isolieren mit Sul- furylchlorid unter Jodzusatz bei 60 bis 700 chloriert.
1,5 Teile des so erhaltenen Chlorierungs- produktes werden bei 1000 in eine Schmelze von 20 Teilen Aluminiumchlorid und 50 Tei len trockenem Pyridin eingetragen. Nun er höht man die Temperatur unter gleichzeitigem Abdestillieren eines Teils des Pyridins in einer halben Stunde auf 140 bis 1420 und rührt eine weitere Stunde bei dieser Temperatur. Die Schmelze wird hierauf in Wasser ausge tragen, mit Natronlauge alkalisch gestellt und mit Hydrosulfit verküpt. Nach der Filtration von wenig Rückstand wird der Farbstoff mit Luft, ausgeblasen, abgenutscht, ausgewaschen und getrocknet.
Zum praktisch gleichen Farbstoff gelangt man auch, wenn man 5 Teile des chlorierten Kondensationsproduktes mit 25 Teilen Alumi niumchlorid und 55 Teilen Py ridin bei 1.10 bis 1420 behandelt.
Additional patent to main patent no. <B> 257722. </B> Process for the production of a vat colorant. It has been found that a valuable vat dye can be produced if the condensation product of 1 mole of 3 ', 6'-1) ihalogen-3,4-phthaloyl-pyrene and 2 moles of 4-amino-7,1'-diantliriinide with Sulfuryl chloride chlorinated at 60 to 700 with the addition of iodine and then treated with earbazolating agents.
The new dye is a black powder that is in conc. Sulfuric acid dissolves with a black-brown color and dyes cotton from a brown vat in olive-gray tones.
Example: The reaction product obtained by condensation in dry nitrobenzene from 1 mol of 3 ', 6'-dihalo-3,4-phthalyl-pyrene and 2 mol of 4-amino-1,1'-dianthrimide with the addition of copper acetate is chlorinated at 60 to 700 with sulphuryl chloride with the addition of iodine without being isolated.
1.5 parts of the chlorination product thus obtained are introduced at 1000 into a melt of 20 parts of aluminum chloride and 50 parts of dry pyridine. Now he increases the temperature while distilling off part of the pyridine in half an hour to 140 to 1420 and stirred for a further hour at this temperature. The melt is then carried out in water, made alkaline with sodium hydroxide solution and vat with hydrosulfite. After a little residue has been filtered off, the dye is blown out with air, suction filtered, washed out and dried.
Practically the same dye is also obtained if 5 parts of the chlorinated condensation product are treated with 25 parts of aluminum chloride and 55 parts of pyridine at 1:10 to 1420.
