Description
Verfahren zur Darstellung eines als Farbstoff und Farbstoffzwischenprodukt verwendbaren Kondensationsproduktes der Anthrachinonreihe. Es wurde befunden, dass man ein neues, als Farbstoff und F.arbstoffzwischenprodukt verwendbares Kondensationsprodukt der An thrachinonreihe erhält, wenn man Cyanur- chlorid und l.-Amino-4-Methoxy-Anthrachino.n miteinander umsetzt.
<I>Beispiel:</I> 253 Teile 1--##@mino-4-Methoxy-Anthrachi- non werden mit 61,5 Teilen Cyanurchlorid in Nitrobenzol erwärmt und während 10 Stun den bei zirka. 100 gerührt. Hierauf wird ent- yvässertes Natriumacetat (200 Teile) zugege ben und nach einer weitern Stunde die Tem peratur auf 115 bis 120' gesteigert. Bei :die- ser wird zirka 2.1 Stunden gehalten.
Nach dem Erkalten wird das ausgeschiedene Re aktionsprodukt abfiltriert und mit Nitroben- zol und darauf mit Alkohol gewaschen, bis letzterer nicht mehr blaurot gefärbt erscheint. Man erhält einen ziegelfarbenen Körper mit je nach der Reaktionsdauer, sowie auch dem angewandten Mengenverhältnis der Aus gangsmaterialien schwankendem -Prozentsatz an' Chlor.
In trockenem Zustand stellt das neue Kondensationsprodukt ein ziegelfar.- benes Pulver dar, das in Wasser unlöslich ist, sich in kaltem und heissem Alkohol wenig mit oranger Farbe, in heissem Chlorbenzol mässig, noch etwas besser in heissem Nitrobenzol mit rotoranger Farbe, in kalter konzentrierter Schwefelsäure mit blutroter Farbe löst und, aus der bräunlichorangen Küpe auf Baum wolle gefärbt, rotorange bis gelbrote Töne liefert.
Process for the preparation of a condensation product of the anthraquinone series which can be used as dye and dye intermediate. It has been found that a new condensation product of the anthrachinone series which can be used as dye and intermediate dye is obtained when cyanuric chloride and l-amino-4-methoxy-anthraquinone are reacted with one another.
<I> Example: </I> 253 parts 1 - ## @ mino-4-methoxy-anthraquinone are heated with 61.5 parts of cyanuric chloride in nitrobenzene and heated for 10 hours at approx. 100 stirred. Dehydrated sodium acetate (200 parts) is then added and, after a further hour, the temperature is increased to 115 to 120 °. At: this is held for about 2.1 hours.
After cooling, the precipitated reaction product is filtered off and washed with nitrobenzene and then with alcohol until the latter no longer appears blue-red. A brick-colored body is obtained with a percentage of 'chlorine which fluctuates depending on the duration of the reaction, as well as the ratio of the starting materials used.
When dry, the new condensation product is a brick-colored powder that is insoluble in water, has a little orange color in cold and hot alcohol, moderately in hot chlorobenzene, even better in hot nitrobenzene with a red-orange color, in cold it is more concentrated Sulfuric acid dissolves with blood-red color and, dyed from the brownish-orange vat on cotton, delivers red-orange to yellow-red tones.
