Description

Verfahren zur Darstellung von Perylenfarbstoffen. In dem Patent 4. i 2 i 2o ist ein Verfahren zur Herstellung von neuen Kondensationsprodukten beschrieben, welches darin besteht, daß man Binaphthyldichinon,oder nessen Derivate bzw. die Reduktionsprodukte dieser Verbindungen mit Aluminiumchlorid bei An- oder Abwesenheit von Verdünnungsmitteln behandelt.Process for the preparation of perylene dyes. In the patent 4. i 2 i 2o describes a process for the production of new condensation products, which consists in the fact that you binaphthyldichinon, or nessen derivatives or the Reduction products of these compounds with aluminum chloride in the presence or absence Treated by diluents.

Es wurde nun gefunden, daß man derartige Kondensationsprodukte auch erhält, wenn man j3-Naphthochinon mit Aluminiumchlorid behandelt. Beispiel i.It has now been found that such condensation products can also be obtained obtained when j3-naphthoquinone is treated with aluminum chloride. Example i.

io Teile ß-Naphthochinon werden mit 4o Teilen Aluminiumchlorid innig vermischt und zweckmäßig unter Fernhaltung von Feuchtigkeit mehrere Stunden auf 14o bis i 5o' erhitzt. Das Reaktionsgemisch läßt man erkalten, zerkleinert es, und kocht es mit verdünnter Salzsäure aus. Man löst in Natronlauge und fällt das neue Kondensationsprodukt, erforderlichenfalls nach dem Filtrieren, mit verdünnter Säure aus. Es ist in allen Eigenschaften identisch mit dem nach Beispiel i des Hauptpatentes erhaltenen Produkt.10 parts of ß-naphthoquinone become intimate with 40 parts of aluminum chloride mixed and expediently while keeping moisture away for several hours Heated 14o to 15o '. The reaction mixture is allowed to cool, it is crushed, and boil it out with dilute hydrochloric acid. One dissolves in caustic soda and drops the new one Condensation product, if necessary after filtering, with dilute acid the end. It is identical in all properties to that according to example i of the main patent received product.

Beispiele. 5 Teile j3-Naphtho-chinon und 2o Teile Aluminium,chlorid werden in ioo Teilen o-Dichlorbenzol suspendiert und mehrere Stunden bei i 4o bis 150' gerührt. Zur Aufarbeitung kann man z. B. das Produkt :absaugen, mit Alkohol waschen und den Rückstand mit verdünnter Salzsäure auskochen. Die weitere Reinigung kann in der in Beispiel i beschriebenen Weise geschehen. Das Produkt ist mit dem nach Beispiel i erhaltenen identisch.Examples. 5 parts of j3-naphtho-quinone and 20 parts of aluminum chloride are suspended in 100 parts of o-dichlorobenzene and stirred for several hours at 14 to 150 minutes. For work-up you can, for. B. the product: suck off, wash with alcohol and boil the residue with dilute hydrochloric acid. The further purification can be carried out in the manner described in Example i. The product is identical to that obtained in Example i.
