Description
Verfahren zur Herstellung eines indigoiden Farbstoffes. Es wurde cefunden, dass man einen wert vollen in#digoiden Farbstoff herstellen kann, %venn man das ss-Thionaphtisatin, beispiels weise erhalten nach dem Verfahren des<B>Pa-</B> tentes Nr. <B>93486,</B> mit 6-Chloroxythionaph-Len- l#arbonsä,ure kondensiert und das so erhaltene Produkt bromiert. Der Farbstoff bildet ein dunkles Pulver,
löst sich in konzentrierter Sch#vefelsäure mit Üunkelblaugrüner Farbe und gibt mit Hydrosulfit und Natronlange eine gelbe Küpe, aus welcher Wolle in licht- und waschechten roten, Baumwolle in sehr lielit-, waseh- und chlorecliten gelbstichigen bordeaux Tönen gefärbt wird.
<I>Beispiel:</I> In<B>7000</B> Teilen Alkohol werden 214 Teile ss-Thiona,phtisatin und 228,5 Teile 6-Chlor- oxythion,ap'htenl"arbonsä,ure eingetragen und hierauf einige Stunden am Rückflusskühler ,0,#ehocht. Die Kondensation kann durch Züi- satz, von Ammoniak oder Dimethylanilin be- sehleunigt werden. Nachdem sie beendet ist, wird filtriert, gewaschen -und getrocknet.
.380,5 Teile des so erhaltenen Produktes werden nun bei<B>0</B> "bis --#5 <B>'</B> in eine Mischung von<B>5700</B> Teilen<B>98</B> '/o-iger Schwefelsäure mit <B>275</B> Teilen Brom eingetragen. Man rührt noch einige Stunden unter Kühlung, #dann lässt man die Temperatur auf 20' steigen und rührt weitere 14 Stunden. Hierauf wird auf Eis ausgetragen,,der abgesehiedene Farbstoff filtriert und getrocknet.
Process for the production of an indigoid dye. It was found that a valuable in # digoid dye can be produced if the ss-thionaphtisatin is obtained, for example, according to the process of <B> Patent </B> tent No. <B> 93486, </ B> condensed with 6-chloroxythionaph-Len- l #arboxylic acid and the product thus obtained is brominated. The dye forms a dark powder,
dissolves in concentrated sulfuric acid with a dark blue-green color and gives a yellow vat with hydrosulphite and soda long, from which wool is dyed in light and washfast red, cotton in very lielite, waseh and chloreclite yellowish burgundy tones.
<I> Example: </I> In <B> 7000 </B> parts of alcohol, 214 parts of ss-thiona, phtisatin and 228.5 parts of 6-chlorooxythion, aphteno-acidic acid are added and then some Hours on the reflux condenser, 0. The condensation can be accelerated by adding ammonia or dimethylaniline. When it is complete, it is filtered, washed and dried.
.380.5 parts of the product obtained in this way are now converted into a mixture of <B> 5700 </B> parts <B> at <B> 0 </B> "to - # 5 <B> '</B> 98% sulfuric acid with 275 parts of bromine is added. The mixture is stirred for a few more hours while cooling, #then the temperature is allowed to rise to 20 ° and stirred for a further 14 hours Discharged on ice, filtered the separated dye and dried.
