Description

Verfahren zur Darstellung von chlorhaltigen Küpenfarbstoffen der Anthrachinonreihe. Die Farbstoffe der Pyrazolanthron- und Thiazolanthronreihe (vgl. die deutschen Patentschriften 255644 301554, 302:259, 343o65 und 359139) gehören zu den chlorechtesten Farbstoffen und setzen der Einwirkung der Halogene großen Widerstand entgegen.Process for the preparation of chlorine-containing vat dyes of the anthraquinone series. The dyes of the pyrazolanthrone and thiazolanthrone series (cf. German patents 255644 301554, 302: 259, 343o65 and 359139) are among the most chlorine-resistant dyes and offer great resistance to the effects of halogens.

Es wurde nun gefunden, daß man trotzdem zu Halogenderivaten gelangt, wenn man die Farbstoffe der Pyrazolanthron- und Thiazolanthronreihe in Oleum oder Chlorsulfonsäure löst und unter Zusatz von Jod Halogene einwirken läßt. Die neuen Derivate zeichnen sich vor den Ausgangsfarbstoffen durch reinere, teilweise vertiefte Nuance und erhöhte Kochechtheit der damit erzielten Färbungen aus.It has now been found that halogen derivatives are still obtained, if you have the dyes of the pyrazolanthrone and thiazolanthron series in oleum or Chlorosulfonic acid dissolves and, with the addition of iodine, allows halogens to take effect. The new Derivatives are distinguished from the starting dyes by purer, partially deepened ones Nuance and increased cooking fastness of the dyeings achieved with it.

ioo Teile des Farbstoffes, dargestellt nach Beispiel 3 des Patentes 301554, werden in iooo Teilen Oleum von 20 Prozent SQ, gelöst. Etwa o,o5 bis o,5 Teile fein gepulvertes Jod werden eingestreut und in die Lösung bei etwa 5o' unter raschem Rühren ein mäßiger Chlorstrom eingeleitet, bis die einem Dichlorderivat entsprechende Chlormenge aufgenommen ist. - Das gebildete Chlorderivat gibt aus blauer Küpe ein klares blaustichiges Rot von hervorragender Echtheit. je nach der Zeitdauer der hlorzufuhr können auch andere Chlorderivate erhalten werden. In gleicher Weise können auch die anderen Farbstoffe der Pyrazolanthron- und Thiazolanthronreihe mit Chlor und mit Brom behandelt werden.100 parts of the dye, prepared according to Example 3 of patent 301554, are dissolved in 100 parts of oleum of 20 percent SQ. About 0.5 to 0.5 parts of finely powdered iodine are sprinkled in and a moderate stream of chlorine is passed into the solution at about 50 'with rapid stirring until the amount of chlorine corresponding to a dichloro derivative has been absorbed. - The chlorine derivative formed gives a clear bluish red of excellent fastness from the blue vat. other chlorine derivatives can also be obtained depending on the duration of the supply of chlorine. The other dyes of the pyrazole anthrone and thiazole anthrone series can also be treated with chlorine and bromine in the same way.
