Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 163280. Verfahren zur Herstellung eines neuen Küpenfarbstoffes. Es wurde gefunden, dass man einen neuen Küpenfarbstoff erhält, wenn man das 5-Clilor- 4.7-diirietbyl-3-oxythionaphtlieri mit dem 2-(p-Dimethylaniino-)anil des 6-Äthoxy-3-oxy- thionaplithens kondensiert.
Der neue Farbstoff der Formel
EMI0001.0009
stellt ein gelbrotes Pulver dar, das sich in konzentrierter Schwefelsäure mit grasgrüner Farbe löst und Baumwolle aus grüngelb ge färbter Küpe in Rosatönen von sehr guter Echtheit färbt.
<I>Beispiel:</I> 212,5 Teile 5-Chlor-4.7-dimethyl-3-oxy- thionaphthen und 326 Teile 2-(p-Dimethyl- amino-)anil des 6-Äthoxy-3-oxythionaphthens werden in 8000 Teilen Benzol zum-Sieden erhitzt, bis die Kondensation beendet ist. Der Farbstoff wird filtriert, gewaschen und getrocknet.
<B> Additional patent </B> to main patent no. 163280. Process for the production of a new vat dye. It has been found that a new vat dye is obtained if the 5-Clilor-4,7-diirietbyl-3-oxythionaphthalene is condensed with the 2- (p-dimethylaniino) anil of the 6-ethoxy-3-oxythionaplithene.
The new dye in the formula
EMI0001.0009
is a yellow-red powder that dissolves in concentrated sulfuric acid with a grass-green color and dyes cotton from a green-yellow vat in pink shades of very good fastness.
<I> Example: </I> 212.5 parts of 5-chloro-4,7-dimethyl-3-oxythionaphthene and 326 parts of 2- (p-dimethylamino-) anil of 6-ethoxy-3-oxythionaphthene are used in 8000 parts of benzene are heated to boiling until the condensation has ended. The dye is filtered, washed and dried.
