Description

Verfahren zur Herstellung von Farbstoffen der Perylenreihe Es wurde gefunden, daß man neue Farbstoffe der Perylenreihe erhält, wenn man Perylentetracarbonsäureanhydrid in wäßriger Suspension bei erhöhter Temperatur mit Verbindtingen der Formel NH2X, worin X = -OH oder -NH2 bedeutet, zu den entsprechenden N-Oxy-imid- bzw. N-Amino-imid-Verbindungen umsetzt. Die so erhaltenen Kondensationsprodukte entsprechen den Formeln Das Verfahren ist bei Phthalsäureanhydrid und bei Naphthalsäureanhydrid bekannt. In Anbetracht der Unlöslichkeit des Perylentetracarbonsäureanhydrids in Wasser war jedoch nicht zu erwarten, daß sich die Kondensation auch hier einwandfrei durchführen läßt.Process for the preparation of dyes of the perylene series It has been found that new dyes of the perylene series are obtained if perylenetetracarboxylic anhydride in aqueous suspension at elevated temperature with compounds of the formula NH2X, where X = -OH or -NH2, to the corresponding N-oxy -imide or N-amino-imide compounds. The condensation products obtained in this way correspond to the formulas The process is known for phthalic anhydride and naphthalic anhydride. In view of the insolubility of the perylenetetracarboxylic anhydride in water, however, it was not to be expected that the condensation could also be carried out properly here.

Das neue N-Oxy-imid ist ein Farbstoff, der sich leicht verküpen läßt. Dadurch unterscheidet er sich besonders von dem Perylentetracarbonsäure-diimid, das nach der deutschen Patentschrift 276 357 erhalten wird und dessen Leukoverbindung schwer löslich ist (s. die französische Patentschrift 1 183 591). The new N-oxy-imide is a dye that can be easily vetted. This distinguishes it in particular from the perylenetetracarboxylic acid diimide, which is obtained according to German patent specification 276 357 and whose leuco compound is sparingly soluble (see French patent specification 1 183 591).

Das erfindungsgemäß erhaltene N-Amino-imid färbt Baumwolle aus dunkelroter Küpe in braunstichigroten Tönen.The N-amino-imide obtained according to the invention dyes cotton from dark red Vat in brownish red tones.

Die erfindungsgemäß herstellbaren Perylentetracarbonsäure-imid-Derivate können auch alsZwischenprodukte zur Herstellung wertvoller Küpen- und Pigmentfarbstoffe verwendet werden. Beispiel 1 40g Perylentetracarbonsäureanhydrid werden in feingepulverter Form mit einer Lösung von 180g Hydroxylaminsulfat in 1000ccm Wasser, die mit etwa 80 ccm Natronlauge 33' B6 so weit abgestumpft worden ist, daß ein pH-Wert von 5 bis 6 erreicht wurde, 16 Stunden unter Rückfluß und Rühren gekocht. Das so entstandene Kondensationsprodukt wird abgesaugt und gewaschen. Es löst sich in konzentrierter Schwefelsäure mit rotvioletter Farbe und orangeroter Fluoreszenz. Aus dunkelroter Küpe färbt es Baumwolle in korinthfarbenen Tönen, die gute Echtheitseigenschaften, insbesondere eine hervorragende Lichtechtheit besitzen.The perylenetetracarboxylic acid imide derivatives which can be prepared according to the invention can also be used as intermediates for the preparation of valuable vat and pigment dyes. Example 1 40g of perylenetetracarboxylic anhydride are finely powdered with a solution of 180g of hydroxylamine sulfate in 1000ccm of water, which has been blunted with about 80cc of 33 ' B6 sodium hydroxide solution to such an extent that a pH of 5 to 6 has been reached, under reflux for 16 hours Stir cooked. The resulting condensation product is filtered off with suction and washed. It dissolves in concentrated sulfuric acid with a red-violet color and orange-red fluorescence. From a dark red vat it dyes cotton in corinthian tones, which have good fastness properties, in particular excellent lightfastness.

Wird die Kondensation unter Druck im Autoklav bei 100'C übersteigenden Temperaturen, z. B. bei 150'C, durchgeführt, so kann die Reaktionszeit wesentlich gekürzt werden.If the condensation under pressure in the autoclave at temperatures exceeding 100'C, e.g. B. at 150'C, carried out, the reaction time can be significantly shortened.

Eventuell nicht umgesetzte Perylentetracarbonsäure kann durch Auswaschen mit verdünnter Natronlauge, der sie eine starke grüne Fluoreszenz erteilt, entfernt werden. Beispiel 2 40 g Perylentetracarbonsäureanhydrid werden in feingepulverter Form mit 50 g Hydrazinhydratlösung (80%) und 10 gHydrazinsulfatinl lWasser8 Stunden rückfließend gekocht. Das so entstandene N-Aminoimid wird abgesaugt und gewaschen. Es löst sich in konzentrierter Schwefelsäure orangerot mit hellroter Fluoreszenz. Aus dunkelroter Küpe färbt es Baumwolle in braunstichigroten Tönen.Any unreacted perylenetetracarboxylic acid can be removed by washing with dilute sodium hydroxide solution, to which it gives a strong green fluorescence. Example 2 40 g of perylenetetracarboxylic acid anhydride in finely powdered form are refluxed for 8 hours with 50 g of hydrazine hydrate solution (80%) and 10 g of hydrazine sulfate / water. The resulting N-aminoimide is filtered off with suction and washed. It dissolves in concentrated sulfuric acid orange-red with light red fluorescence. From a dark red vat it dyes cotton in brownish red tones.
