Description
Verfahren zur Darstellung eines Chlor und Brom enthaltenden ltüpenfarbstoffes. 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 Mol Isodi- benzanthron in Gegenwart von Chlorsulfon- säure und Selen, eventuell unter Zusatz von Jod, mit mindestens 11/; Mol eines bromie- renden Mittels behandelt.
Der erhaltene Küpenfarbstoff, ein .Tri- bromdichlorisodibenzanthron, ist ein violet tes Pulver, löst sich in konzentrierter Schwefelsäure mit grüner Farbe und liefert auf Baumwolle aus blauer Küpe klare, kräf tige, rotviolette Färbungen von hervorragen den Echtheitseigenschaften.
<I>Beispiel 1:</I> Eine Lösung von Vif; Teilen Isodilbc@uz- anthron in .160 Teilen Chlorsulfonäure wird nach Zugabe von I Teilen Selen bei gewöhi- licher Temperatur mit 35 Teilen Brom ver setzt 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.
<I>Beispiel 2:</I> Man löst bei gewöhnlicher Temperatur 46 Teile Isodibenzanthron in 460 Teilen Chlorsulfonsäure, gibt .l Teile Jod und Teile Selen zu und lässt unter Rühren 35 Teile Brom zufliessen. Hierauf erhöht man die Temperatur langsam auf<B>70'</B> C. rührt, bis die Hauptmenge des Broms auf genommen ist, lässt erkalten und arbeitet wie üblich auf.
Process for the preparation of an inflatable dye containing chlorine and bromine. The main patent describes a process for preparing 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 mol of isodibenzanthrone is added in the presence of chlorosulfonic acid and selenium, possibly with the addition of iodine, with at least 11 /; Moles of a brominating agent treated.
The vat dye obtained, a tri-bromodichloroisodibenzanthrone, is a violet powder, dissolves in concentrated sulfuric acid with a green color and provides clear, strong, red-violet dyeings with excellent fastness properties on cotton from a blue vat.
<I> Example 1: </I> A solution from Vif; Parts of Isodilbc @ uzanthron in .160 parts of chlorosulfonic acid are added, after the addition of 1 parts of selenium, to 35 parts of bromine at the usual temperature and heated to 65 to 70 ° C. with stirring until most of the bromine has been absorbed. You let it cool down and work up in the usual way.
Example 2: 46 parts of isodibenzanthrone are dissolved in 460 parts of chlorosulfonic acid at ordinary temperature, 1 part of iodine and parts of selenium are added and 35 parts of bromine are allowed to flow in with stirring. The temperature is then slowly increased to <B> 70 '</B> C. Stir until most of the bromine has been absorbed, allow to cool and work up as usual.
