Description
Zusatzpatent zum Hauptpatent Nr.<B>151335.</B> Verfahren zur Herstellung eines neuen güpenfarbstoffes. Es wurde gefunden, dass man einen neuen güpenfarbstoff erhält, wenn man das p-Di- methylaminoanil des 5-Chlor-6-methyl-3-oxy- thionaphtens mit 2. 1-Naphthoxythiophen kon densiert.
Der neue Farbstoff der Formel
EMI0001.0010
stellt ein braunes Pulver dar, das Baumwolle aus orangefarbiger Küpe in kräftigen, gelb- stichigen Bordeauxtönen färbt, die sehr gute Chlor-, Wasch-, und Beuchechtheit zeigen.
<I>Beispiel:</I> 330 Teile p-Dimethylaminoanil des 5-Chlor- 6-methyl-3-oxythionaphtens und 200 Teile 2. 1-Naphthoxythiophen werden in 4000 Teilen Alkohol suspendiert und zum Sieden erhitzt, bis die Kondensation zum Farbstoffe beendet ist. Man filtriert, wäscht mit Alkohol und trocknet.
Additional patent to main patent no. <B> 151335. </B> Process for the production of a new high-quality dye. It has been found that a new grade dye is obtained if the p-dimethylaminoanil of 5-chloro-6-methyl-3-oxythionaphthene is condensed with 2. 1-naphthoxythiophene.
The new dye in the formula
EMI0001.0010
is a brown powder that dyes cotton from an orange vat in strong, yellow-tinged bordeaux tones, which are very fast to chlorine, washing and laundry.
<I> Example: </I> 330 parts of p-dimethylaminoanil of 5-chloro-6-methyl-3-oxythionaphthene and 200 parts of 2. 1-naphthoxythiophene are suspended in 4000 parts of alcohol and heated to the boil until the dyes condense is finished. It is filtered, washed with alcohol and dried.
