Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines neuen Kon densationsproduktes und ist dadurch gekenn zeichnet, dass man das nach dem Verfahren der Patentsehrift Nr.251646 erhältliehe bro- niierte Nalilithocliinonimid mit Phenol kon densiert.
<I>Beispiel:</I> 17,3 g des nach dem Beispiel der Patent schrift Nr. 251646 erhältlichen bromierten Naphthochinonimids werden in 200 ein:' Ätha nol aufgeschwemmt und nach Zusatz von 23,8 g Phenol, 0,5 g Borsäure und 5 g Na- t.riuniacetat während 18 Stunden zum Sieden erhitzt. Nach dieser Zeit, destilliert man den Alkohol ab, trägt das Kondensationsprodukt in Wasser ein, versetzt mit Natriumhydroxy d bis zur phenolphthaleinalkalischen Reaktion, filtriert und wäscht gut nach.
Man erhält ein dunkles Pulver, (las in Äthanol mit korn- blumenblauer und in 1-1-SO 4 mit gelboliver Farbe löslich ist und pflanzliche Fasern aus einem Natriumsulfid-Bade in einem tiefen Marineblau färbt.. Die Verbindung eignet siele zum Färben von Aeetatseide.
Process for the production of a new condensation product. The present invention relates to a process for the production of a new condensation product and is characterized in that the bronzed nalilithocliinonimide obtained according to the process of patent application No. 251646 is condensed with phenol.
<I> Example: </I> 17.3 g of the brominated naphthoquinonimide obtainable according to the example of patent specification no. 251646 are suspended in an: Ethanol and after adding 23.8 g of phenol, 0.5 g of boric acid and 5 g Na- t.riuniacetat heated to boiling for 18 hours. After this time, the alcohol is distilled off, the condensation product is introduced into water, sodium hydroxide is added until the phenolphthalein-alkaline reaction occurs, and the mixture is filtered and washed thoroughly.
A dark powder is obtained which is soluble in ethanol with cornflower blue and in 1-1-SO 4 with yellow-olive color and dyes vegetable fibers from a sodium sulfide bath in a deep navy blue. The compound is suitable for dyeing acetate silk .
