Description
Verfahren zur Herstellung eines stickstoffhaltigen Kondensationsproduktes des Fluoranthens. Es wurde gefunden, dass ein stickstoff haltiges Kondensationsprodukt des, Fluor- anthens hergestellt werden kann, wenn man Di- (4'-benzoylamino-1'-anthrachinonyl) -di;- s aminofluoranthen mit kondensierenden Mit teln behandelt.
Das neue Kondensationsprodukt ist ein schwarzes Pulver, das Baumwolle aus schwarzoliver güpe in reinen schwarzbrau- io nen Tönen färbt.
Das dem Verfahren als Ausgangsprodukt dienende Di-(4'-benzoylamino-1'-anthrachi- nonyl)-diaminofluoranthen kann durch Um setzen von 1 Mol Däbromfluoranthen mit 1s 2 Mol 1-Amino-4-benzoylaminoanthrachinon, beispielsweise nach dem Verfahren des Pa tentes Nr. 208953, erhalten werden.
Als kondensierende Mittel, die sauren oder alkalischen Charakter besitzen und die 2o für sich allein, gegebenenfalls miteinander kombiniert oder zusammen mit indifferenten Lösungs- bezw. Verdünnungsmitteln verwen det werden können, kommen in Betracht: Aluminiumchlorid, Natriumamid, Acetyl- chlorid, Benzoylchlorid, Chlorsulfonsäure und besonders hochprozentige, Schwefelsäure.
Die Einwirkung der kondensierenden Mittel kann bei tiefer, mittlerer oder gegebenen falls stark erhöhter Temperatur vorgenom men werden. <I>Beispiel:</I> 1 Teil Di--(4'-benzoylamino-1'-anthra- chinonyl)-diamino-fluoranthen, erhalten nach ,dem Verfahren des Patentes Nr. 208953, wird bei<B>60-65'</B> in 18,2 Teile 90% ige Schwefelsäure eingetragen und 3-4 Stunden bei<B>60-65)</B> gerührt. Nun trägt man in Eis, gibt 0,3 Teile Natriumnitrit zu und rührt 16 Stunden bei 0---5 . Der .erhaltene Farb stoff wird erbfiltriert, gewaschen und ge trocknet.
Process for the preparation of a nitrogen-containing condensation product of fluoranthene. It has been found that a nitrogen-containing condensation product of fluoroanthene can be produced if di- (4'-benzoylamino-1'-anthraquinonyl) -di; - s aminofluoranthene is treated with condensing agents.
The new condensation product is a black powder that dyes cotton from black olive güpe in pure black-brown tones.
The di- (4'-benzoylamino-1'-anthraquinoneyl) -diaminofluoranthene, which is used as the starting product, can be converted into 2 moles of 1-amino-4-benzoylaminoanthraquinone, for example by the method of the patent No. 208953.
As condensing agents which have acidic or alkaline character and which can be used alone, optionally combined with one another or together with indifferent solutions or. Diluents that can be used are: aluminum chloride, sodium amide, acetyl chloride, benzoyl chloride, chlorosulfonic acid and especially high-percentage sulfuric acid.
The action of the condensing agents can be made at low, medium or, if necessary, greatly increased temperature. <I> Example: </I> 1 part of di - (4'-benzoylamino-1'-anthraquinonyl) -diamino-fluoranthene, obtained according to the process of patent no. 208953, is at <B> 60- 65 'entered in 18.2 parts of 90% strength sulfuric acid and stirred for 3-4 hours at <B> 60-65) </B>. Now it is carried in ice, 0.3 part of sodium nitrite is added and the mixture is stirred for 16 hours at 0-5. The dyestuff obtained is inherited by filtration, washed and dried.
