Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 10070"0. Verfahren zur Herstellung eines neuen indigoiden Farbstoffes. Es wurde gefunden, dass man eineu neuen indigoiden Farbstoff erhält, wenn man das 4-Chlor-1 . 2-tbionaplithisatin, welches durch Kondensieren von 4-Chlor-1-thionaphtliol mit Oxalylchlorid erhalten werden kann, mit Oxy- thionaphtenkarbonsäure kondensiert und das erhaltene Produkt bromiert.
Der neue Farbstoff bildet ein rotes Pulver, löst sich in konz. Schwefelsäure mit grüner Farbe und gibt mit Hy drosulfit und Natron lauge eine gelbe Küpe, aus welcher Baum wolle in blauen Bordeauxtönen gefärbt wird, die beim Seifen etwas röter und sehr echt werden.
<I>Beispiel</I> In 10000 Teile Alkohol werden 248,5 Teile 4-Clilor-1 . 2-thionapbtliisatin und 194 Teile Oxy thionaphtenkarbonsäure eingetragen und hierauf längere Zeit am Rückflusskühler gekocht. Der gebildete Farbstoff wird filtriert, gewaschen und getrocknet.<B>380</B> Teile des so er haltenen Farbstoffes werden bei 0 bis 5 in eine Yischung von 9000 Teilen 98 /oiger Schwefel- säure mit 144 Teilen Brom eingetragen und 12 Stunden bei gewöbnlicher Temperatur ge rührt.
Hierauf wird auf Eis ausgetragen, der abgeschiedene Farbstoff filtriert und getrock net. Diese Bromierung kann auch in einem indifferenten Lösungsmittel, wie Nitrobenzol oder Chlorbenzol, durchgeführt werden.
<B> Additional patent </B> to main patent No. 10070 "0. Process for the preparation of a new indigoid dye. It has been found that a new indigoid dye is obtained if 4-chloro-1,2-tbionaplithisatin, which can be obtained by condensing 4-chloro-1-thionaphthiol with oxalyl chloride, condensed with oxythionaphtenecarboxylic acid and the product obtained is brominated.
The new dye forms a red powder, dissolves in conc. Sulfuric acid with a green color and, with hydrosulphite and sodium hydroxide solution, gives a yellow vat from which cotton is dyed in blue bordeaux tones, which become a little redder and very real when soapy.
<I> Example </I> In 10,000 parts of alcohol there are 248.5 parts of 4-Clilor-1. Entered 2-thionapbtliisatin and 194 parts of Oxy thionaphtenkarbonsäure and then boiled for a long time on the reflux condenser. The dyestuff formed is filtered, washed and dried. 380 parts of the dyestuff obtained in this way are added at 0 to 5 to a mixture of 9000 parts of 98% sulfuric acid with 144 parts of bromine and added for 12 hours ordinary temperature ge stirred.
It is then poured onto ice, the deposited dye is filtered and net getrock. This bromination can also be carried out in an inert solvent such as nitrobenzene or chlorobenzene.
