Description
Verfahren zur Darstellung eines Chlor und Brom enthaltenden Küpenfarbstoffes. Im Hauptpatent ist ein Verfahren zur Darstellung eines Chlor und Brom ent haltenden Küpenfarbstoffes beschrieben, bei dem 1 Mol Isodibenzanthron in Gegenwart von Chlorsulfonsäure und von Katalysatoren mit mindestens einem halben Mol eines bro- mierenden Mittels behandelt wird.
Es wurde nun gefunden, dass man einen Farbstoff von ähnlichen Eigenschaften erhalten kann, wenn man 1 1M1 Di- benzanthron in Gegenwart von Chlorsulfon- säure und Schwefel mit mindestens 11/2 Mol eines bromierenden Mittels behandelt.
Der erhaltene Küpenfarbstoff, ein Tri- brommonochlordibenzanthron, ist ein violett blaues Pulver, löst sich in konzentrierter Schwefelsäure mit violetter Farbe und liefert auf Baumwolle aus violetter Küpe klare, kräftige, marineblaue Färbungen von hervor ragenden Echtheitseigenschaften. <I>Beispiel:</I> Eine Lösung von 46 Teilen Dibenz- anthron in 460 Teilen Chlorsulfonsäure wird nach Zugabe von 4 Teilen Schwefel bei ge wöhnlicher Temperatur mit 35 Teilen Brom versetzt und so lange unter Rühren auf 65 bis 70 C erwärmt bis die Hauptmenge des Broms aufgenommen ist.
Man lässt erkalten und arbeitet in der üblichen Weise auf.
Process for the preparation of a vat dye containing chlorine and bromine. The main patent describes a process for the preparation of a vat dye containing chlorine and bromine, in which 1 mole of isodibenzanthrone is treated in the presence of chlorosulfonic acid and catalysts with at least half a mole of a brominating agent.
It has now been found that a dye with similar properties can be obtained if 1 1M1 of dibenzanthrone is treated in the presence of chlorosulfonic acid and sulfur with at least 11/2 mol of a brominating agent.
The vat dye obtained, a tribromomonochlorodibenzanthrone, is a violet-blue powder, dissolves in concentrated sulfuric acid with a violet color and provides clear, strong, navy-blue dyeings with excellent fastness properties on cotton from a violet vat. <I> Example: </I> A solution of 46 parts of dibenzanthrone in 460 parts of chlorosulfonic acid is mixed with 35 parts of bromine at normal temperature after adding 4 parts of sulfur and heated to 65 to 70 ° C. with stirring until the Most of the bromine is absorbed.
You let it cool down and work up in the usual way.
