Description
Zusatzpatent zum Hauptpatent Nr. 257722. Verfahren zur Herstellung eines Küpenfarbstoffes. Es wurde gefunden, dass ein wertvoller Küpenfarbstoff hergestellt werden kann, wenn man das Kondensationsprodukt. aus 1. Mol 3',6'-Diehlorphthaloylfluorantlien und 2 1Io1 1-Amino-5-benzoylamiiioanthrachinoii mit car- bazolierenden Mitteln behandelt.
Der neue Farbstoff ist ein dunkles Pulver, das Baumwolle aus oliver Küpe in schwärz liehbraunen Tönen färbt.
<I>Beispiel:</I> Eine innige Mischung von 25 Teilen Alu miniumchlorid und 4 Teilen Natriumchlorid wird durch Einleiten von Schwefeldioxyd ver flüssigt. In die entstandene Schmelze trägt man nun 2 Teile des Kondensationsproduktes aus 1 Mol 3',6'-Dichlorphthaloylfluoranthen und 2 Mol 1-Amino-5-benzoylaminoant.hrachi- non ein. Nach je einstündigem Rühren bei 40 bis 450 und 85 bis 900 ist die Reaktion beendet.
Man trägt das Umsetzungsgemisch auf Eis aus, gibt 20 Teile konzentrierte Salzsäure hinzu, erhitzt zum Sieden und saugt den aus gefallenen Farbstoff ab. Er wird säurefrei gewaschen und anschliessend in 200 Teilen 5 ?G iger Schwefelsäure verteilt. Man kühlt nun auf 0 bis 5 ab, gibt 0,6 Teile Natrium nitrit zu und rührt die Suspension mehrere Stunden bei 0 bis 50. Der so erhaltene Farb stoff wird abgesaugt, gewaschen und mit Wasser v erpastet.
Additional patent to main patent No. 257722. Process for the production of a vat dye. It has been found that a valuable vat dye can be made by using the condensation product. of 1. Mol 3 ', 6'-Diehlorphthaloylfluorantlien and 2 1Io1 1-Amino-5-benzoylamiiioanthrachinoii treated with carbazolating agents.
The new dye is a dark powder that dyes cotton from an olive vat in blackish brown tones.
<I> Example: </I> An intimate mixture of 25 parts of aluminum chloride and 4 parts of sodium chloride is liquefied by introducing sulfur dioxide. 2 parts of the condensation product of 1 mole of 3 ', 6'-dichlorophthaloyl fluoranthene and 2 moles of 1-amino-5-benzoylaminoanthrachinone are then introduced into the melt formed. After stirring for one hour at 40 to 450 and 85 to 900, the reaction is complete.
The reaction mixture is discharged onto ice, 20 parts of concentrated hydrochloric acid are added, the mixture is heated to boiling and the dyestuff which has precipitated out is filtered off with suction. It is washed free of acid and then distributed in 200 parts of 5% sulfuric acid. It is then cooled to 0 to 5, 0.6 part of sodium nitrite is added and the suspension is stirred for several hours at 0 to 50. The dye thus obtained is filtered off with suction, washed and pasted with water.
