  <B>Zusatzpatent</B> zum Hauptpatent Nr. 100705.    Verfahren zur Herstellung eines     indigoiden        Farbstoffes.       Es wurde gefunden,     dass,    man einen     wert-          vollen        indigoiden    Farbstoff herstellen kann,  wenn man das     ss-Thionaphtssatin,        beispiels-          weise    erhalten nach dem Verfahren des Pa  tentes Nr.

   93486, .mit     Oxythionaphten    kon  densiert und das so erhaltene     Produkt        bro-          miert.    Der Farbstoff bildet     ein    dunkles Pul  ver, löst sieh in konzentrierter     Schwefelsäure     mit     dunkelblaugrüner    Farbe und     gibt    mit       Hydrosulfit    und Natronlauge     eine    gelbe       Küpe,    aus welcher Wolle in licht und     wasch-          echten    roten, Baumwolle in sehr licht-,

       wasch-          und    chlorechten     bordeaux    Tönen gefärbt  wird.  



       Beispiel:     <B>In</B> 7000 Teilen     Alkohol    werden 214 Teile       ss-Thionaphtisatin    und 150 Teile     Oxythio-          naphten    eingetragen und hierauf einige Stun  den am     Rückflusskühler    gekocht. Die Kon  densation kann durch Zusatz von Ammoniak  oder     Dimethyl.ani:lin        beschleunigt    werden.       Nachdem    sie beendet ist,     wird    filtriert, ge  waschen und getrocknet.

      Die gleiche Reaktion findet auch statt,       wenn        idie    Komponenten     zusammen    in Chlor  benzol,     zweckmässig    in Gegenwart eines     Kon-          -densationsmittels,    wie Chlorzink, erwärmt  werden, oder mit     .Schwefelsäure    und     Eisessig     behandelt werden.  



  346 Teile des so erhaltenen     Produktes          werden    nun bei 0       bis    +5<B>'</B>in eine Mischung  von 9000 Teilen 98     %-iger    Schwefelsäure mit  144 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     abgeschiedene    Farbstoff  filtriert und getrocknet.



  <B> Additional patent </B> to main patent no. 100705. Process for the production of an indigoid dye. It has been found that a valuable indigoid dye can be produced if the β-thionaphthosatin, obtained for example by the process of patent no.

   93486, condensed with oxythionaphthene and the product obtained in this way brominated. The dye forms a dark powder, dissolves in concentrated sulfuric acid with a dark blue-green color and gives a yellow vat with hydrosulfite and sodium hydroxide solution, from which wool in light and washable red, cotton in very light,

       Washable and chlorine-resistant burgundy tones.



       Example: 214 parts of ss-thionaphthisatin and 150 parts of oxythionaphthene are added to 7000 parts of alcohol and then boiled for a few hours on the reflux condenser. The condensation can be accelerated by adding ammonia or Dimethyl.ani: lin. After it is finished, it is filtered, washed and dried.

      The same reaction also takes place if the components are heated together in chlorobenzene, expediently in the presence of a condensation agent such as zinc chloride, or are treated with sulfuric acid and glacial acetic acid.



  346 parts of the product thus obtained are then introduced at 0 to +5 into a mixture of 9000 parts of 98% strength sulfuric acid with 144 parts of bromine. The mixture is stirred for a few more hours with cooling, then the temperature is allowed to rise to 20 'and stirred for a further 14 hours. It is then poured onto ice, and the deposited dye is filtered and dried.
