Description
Verfahren zur Herstellung eines Chrysenderivates. Es wurde gefunden, dass ein Chrysende- rivat hergestellt werden kann, wenn man 1 1Mo1 2,8-Dihalogenchrysen mit 1 Mol 1- Amino-4-berizoylaminoairthrachinon umsetzt.
Das so in sehr guter Ausbeute erhältliche Umsetzungsprodukt bildet nach dem Umkri- stallisieren aus a-Chlornaphthalin kleine, blaue Nädelchen vom Zersetzungspunkt 380 , die sich in konzentrierter Schwefelsäure mit grüngelber Farbe lösen. Die Lösungsfarbe schlägt bald nach braunolive um. Das neue Umsetzungsprodukt stellt ein wertvolles Zwi schenprodukt dar, das insbesondere zur Her stellung von Farbstoffen verwendet werden kann.
Die Unisetzung der 2,8-Dihalogenuhi,ysene mit 1-Amino-4-beiizoylaminoanthrachinon wird vorteilhaft durch Erhitzen ihrer Komponenten in Lösungs- oder Verdünnungsmitteln, wie z. B. Nitrobenzol, Chlornaphthalin oder Amyl- alkohol und zweckmässig in Gegenwart von Verbindungen, die die.Abspaltung von Ha logenwasserstoff erleichtern, wie Kupfer oder Kupferverbindungen, sowie von - säurebinden den Mitteln, wie Alkalikarbonaten und/oder entwässertem Natriumacetat durchgeführt.
Beispiel: 9 Teile entwässertes Natriumacetat und 9 Teile kalt. Soda werden mit 480 Teilen Nitrobenzol so lange im Sieden gehalten, bis 48 Teile Nitrobenzol abdestilliert sind. Nach dem Abkühlen auf 160-1950 werden 23,2 Teile 2,8-Dibromchrysen, erhalten durch Di- bromieren von Chrysen in Nitrobenzol, 21 Teile 1-Amino-4-benzoylaminoantbrachinon und 0,75 Teile Kupferchlorür zugefügt und 16 Stunden bei 160-165 gerührt.
Nun wird heiss filtriert, der Rückstand mit Nitrobenzol, Benzol und Alkohol gewaschen und zur Rei nigung mit verdünnter Salzsäure ausgekocht, abfiltriert, ausgewaschen und nochmals mit Alkohol ausgezogen.
Process for the production of a chrysene derivative. It has been found that a chrysene derivative can be produced if 1 mol of 2,8-dihalochrysenic is reacted with 1 mol of 1-amino-4-berizoylaminoairthraquinone.
The reaction product, which can be obtained in this way in very good yield, forms, after recrystallization from α-chloronaphthalene, small, blue needles with a decomposition point of 380, which dissolve in concentrated sulfuric acid with a green-yellow color. The solution color soon changes to brown olive. The new reaction product is a valuable inter mediate product that can be used in particular for the manufacture of dyes.
The conversion of the 2,8-Dihalogenuhi, ysene with 1-amino-4-beiizoylaminoanthraquinone is advantageous by heating its components in solvents or diluents, such as. B. nitrobenzene, chloronaphthalene or amyl alcohol and expediently carried out in the presence of compounds that facilitate the separation of hydrogen halide, such as copper or copper compounds, and of - acid-binding agents such as alkali carbonates and / or dehydrated sodium acetate.
Example: 9 parts dehydrated sodium acetate and 9 parts cold. Soda is kept at the boil with 480 parts of nitrobenzene until 48 parts of nitrobenzene have distilled off. After cooling to 160-1950, 23.2 parts of 2,8-dibromochrysene, obtained by dibrominating chrysene in nitrobenzene, 21 parts of 1-amino-4-benzoylaminoantbrachinone and 0.75 part of copper chloride are added and the mixture is heated at 160 ° for 16 hours. 165 stirred.
The mixture is then filtered hot, the residue is washed with nitrobenzene, benzene and alcohol and boiled with dilute hydrochloric acid for cleaning, filtered off, washed and extracted again with alcohol.
