Description
Zusatzpatent zum Hauptpatent Nr. 151335. Verfahren zur Herstellung eines neuen güpenfarbstoi%s. Es wurde gefunden, dass man einen neuen Küpenfarbstoff erhält, wenn man 5,6-Dichlor- 3-oxythionaphthen mit dem p-Diinethylamino- anil des 2,3-Naphtthioindoxyls kondensiert. Der neue Farbstoff der Formel
EMI0001.0010
stellt ein grauviolettes Pulver dar, das sich in konzentrierter Schwefelsäure mit grüner Farbe löst.
Er gibt mit Hydrosulfit und Natronlauge eine orange gefärbte Küpe, aus der Baumwolle in sehr echten dunkelvioletten Tönen gefärbt wird.
<I>Beispiel:</I> 218 Teile 5,6-Dichlor-3-oxythionaphthen und 332 Teile p-Diinethylamirroanil des 2,3- Naphtthioindoxyls werden in 4000 Teilen Alkohol zum Sieden erhitzt, bis die Konden- sation zum Farbstoff beendet ist. Man filtriert und trocknet.
Additional patent to main patent No. 151335. Process for the production of a new güpenfarbstoi% s. It has been found that a new vat dye is obtained if 5,6-dichloro-3-oxythionaphthene is condensed with the p-diinethylaminoanil of 2,3-naphthioindoxyl. The new dye in the formula
EMI0001.0010
is a gray-violet powder that dissolves in concentrated sulfuric acid with a green color.
He gives an orange colored vat with hydrosulphite and caustic soda, from which cotton is dyed in very real dark purple tones.
<I> Example: </I> 218 parts of 5,6-dichloro-3-oxythionaphthene and 332 parts of p-diinethylamirroanil of 2,3-naphthioindoxyl are heated to the boil in 4000 parts of alcohol until the condensation to the dye has ended . Filter and dry.
