Description
Verfahren zur Herstellung eines stickstoffhaltigen Kondensationsproduktes. Im Hauptpatent ist ein Verfahren zur Herstellung eines stickstoffhaltigen Konden sationsproduktes beschrieben, bei dem ein ms-Halogen -<B>2.3</B> - phthaloylchinolin mit 2- Aminoanthrachinon kondensiert wird.
Es wurde nun gefunden, dass man ein ähnlich wertvolles Kondensationsprodukt er hält, wenn man 1 Mol eines ms-Halogen-7- chlor-2.3-phthaloylchinolins mit 1 Mol 2- Aminoanthrachinon kondensiert.
Die Kondensation wird zweckmässig in Gegenwart von Lösungs- oder Verdünnungs mitteln durchgeführt, gegebenenfalls können auch säurebindende Mittel oder reaktions fördernde Stoffe, wie Kupferverbindungen, zugesetzt werden.
Das erhaltene Kondensationsprodukt löst sich in konzentrierter Schwefelsäure mit orangeroter Farbe und liefert aus schwarz grüner Küpe auf Baumwolle klare gelbe Töne von sehr guten Echtheitseigenschaften. Beispiel.: Eine Mischung aus 65 Teilen ms-Chlor- 7-chlor-2.3-phthaloylchinolin (erhältlich durch Kondensation von a-Naphthochinon mit 4- Chloranthranilsäure,
Ringschluss der entstan denen Naphthochinonylanthranilsäuremit kon zentrierter Schwefelsäure zum Benzakridon- chinon und Umsetzung des erhaltenen Benz- akridonehinons mit Phosphorpentachlorid oder Thionylchlorid), 44 Teilen 2-Aminoanthra- chinon und 1000 Teilen Nitrobenzol wird solange unter Rühren zum Sieden erhitzt, bis kein Chlorwasserstoff mehr entweicht. Man lässt dann erkalten, saugt ab und wäscht den Rückstand mit Methanol aus.
Process for the production of a nitrogen-containing condensation product. The main patent describes a process for the production of a nitrogen-containing condensation product in which an ms-halogen - <B> 2.3 </B> - phthaloylquinoline is condensed with 2-aminoanthraquinone.
It has now been found that a similarly valuable condensation product is obtained if 1 mol of an ms-halo-7-chloro-2,3-phthaloylquinoline is condensed with 1 mol of 2-aminoanthraquinone.
The condensation is expediently carried out in the presence of solvents or diluents; acid-binding agents or substances that promote reactions, such as copper compounds, can optionally also be added.
The condensation product obtained dissolves in concentrated sulfuric acid with an orange-red color and, from a black and green vat on cotton, gives clear yellow tones with very good fastness properties. Example: A mixture of 65 parts of ms-chloro-7-chloro-2,3-phthaloylquinoline (obtainable by condensation of a-naphthoquinone with 4-chloroanthranilic acid,
Ring closure of the resulting naphthoquinonylanthranilic acid with concentrated sulfuric acid to form benzakridonequinone and reaction of the resulting benzacridonequinone with phosphorus pentachloride or thionyl chloride), 44 parts of 2-aminoanthranilic acid and 1000 parts of nitrobenzene are heated to boiling with stirring until no more hydrogen chloride escapes. It is then allowed to cool, filtered off with suction and the residue is washed out with methanol.
