Description
Verfahren zur Herstellung eines Fluoranthenderivates. Es wurde gefunden"dass ein Fluoranthen- derivat hergestellt werden kann, wenn. man 1 Mol Dihalogenfluoranthen mit 2 Molen 1- Amino - 4 - benzoylaminoanthraohinon um setzt.
Das erhaltene Produkt ist ein grünlich- schwarzes, kristallines Pulver, das konzen trierte Schwefelsäure oliv färbt, bei 410' schmilzt und sehr schwer verküpt. Auf Grund der Analyse liegt :das Di-(4'-benzoyl- amino-1'-anthrachinonyl)-diaminofluoranthen vor. Es stellt ein wertvolles Zwischenprodukt zur Herstellung von güpenfarfstoffen dar.
Das dem Verfahren als Ausgangsstoff dienende Dihalogenfluoranthen kann durch. Halogennieren von Fluoranthen biss zum Ein tritt von 2 Halogenatomen, z. B. in Nitro- benzol, hergestellt werden..
Die Umsetzung des Dihalogenfluoranthens mit 1- Amino - 4 - benzoylaminoanthrachinon wird vorteilhaft durch Erhitzen .der Kompo nenten in Lösu ngs- oder Verdünnungsmitteln, wie z. B. Amylalkohol, Nitrtibenzol oder Naphthalin, und zweckmässig in. Anwesenheit von Katalysatoren, sowie von säurebindenden Mitteln durchgefürt.
<I>Beispiel:</I> 18 Teile entwässertes Natriumacetat und 18 Teile wasserfreies Natriumacetat werden mit 8:
80 Teilen Nitrobenzol oo lange im Sie den gehalten, bis 50 Teile Nitrobenzol ab destilliert sind. Nach dem Abkühlen auf 200' werden 21,6 Teile Dibromfluoranthen, erhalten durch Bromieren von Fluoranthen in Nitiobenzol, 46 Teile 1-Amino-4-benzoyl- amino-anthrachinon und 1;
6 Teile Kupfer ohlorür zugesetzt und 4'8 Stunden bei 195 bis <B>205'</B> gerührt. Nun wird heiss filtriert, mit Nitrobenzol sowie mit Benzol und Alko hol gewaschen und das erhaltene Produkt zur weiteren Reinigung mit verdünnter Salz- säure ausgekocht, abfiltriert, ,
gewaschen und getrocknet.
Process for the production of a fluoranthene derivative. It has been found that a fluoranthene derivative can be prepared if 1 mole of dihalofluoranthene is reacted with 2 moles of 1-amino-4-benzoylaminoanthraquinone.
The product obtained is a greenish-black, crystalline powder which gives concentrated sulfuric acid an olive color, melts at 410 'and vents with great difficulty. Based on the analysis: the di- (4'-benzoylamino-1'-anthraquinonyl) diaminofluoranthene is present. It is a valuable intermediate product for the production of güpenfarfstoffe.
The process as starting material used dihalofluoranthene can by. Halogen kidneys of fluoranthene up to a occurs from 2 halogen atoms, z. B. in nitrobenzene.
The reaction of the dihalofluoranthene with 1-amino-4-benzoylaminoanthraquinone is advantageous by heating the components in solvents or diluents, such as. B. amyl alcohol, nitrtibenzene or naphthalene, and expediently carried out in the presence of catalysts and acid-binding agents.
<I> Example: </I> 18 parts of dehydrated sodium acetate and 18 parts of anhydrous sodium acetate are mixed with 8:
80 parts of nitrobenzene are kept in the oven for a long time until 50 parts of nitrobenzene have distilled off. After cooling to 200 ', 21.6 parts of dibromofluoranthene, obtained by brominating fluoranthene in nitiobenzene, 46 parts of 1-amino-4-benzoylamino-anthraquinone and 1;
6 parts copper oxide added and stirred for 4'8 hours at 195 to <B> 205 '</B>. It is then filtered hot, washed with nitrobenzene and with benzene and alcohol and the product obtained is boiled for further purification with dilute hydrochloric acid, filtered off,,
washed and dried.
