  Zusatzpatent zum Hauptpatent     Nr.   <B>100705.</B>    Verfahren zur Herstellung eines neuen     indigolden    Farbstoffes-    Es wurde gefunden,     dass    man einen neuen       indigoiden    Farbstoff     erhäft,    wenn man das       2,3-Thionaphth-isatin    (hergestellt zum Bei  spiel aus     2,ä-Naphthtliioindoxyl    durch     Kon-          clensieren    mit     Nitrosodimethylanilin    und<B>Ab-</B>  spalten von     Ami-nodimethyli.nilin    aus     dem     gebildeten Anilin)

   mit<B>6 -</B>     Chloroxythio-          naphtlienkarbonsäure    kondensiert und das so       crIraltene    Produkt     bromiert.     



  Der neue Farbstoff stellt ein violettes  Pulver dar, das sich in Schwefelsäure mit  grüner Farbe, löst. Mit     Hydro-sulfit    und Na  tronlauge bildet es eine orangerote     Küpe    und       f-ii,rbt    daraus Baumwolle in     violettroten    Tö  nen von sehr guter Echtheit.  



  <I>Beispiel:</I>  In<B>5000</B> Teile Alkohol -werden 214 Teile  2,3<B>-</B>     Thional)htliisatin    und<B>22,5</B> Teile     6-          Cliloroxythionaphthenkarbonsäure    eingetra  gen. Nach Beigabe von<B>5</B> Teilen     Ammoniak     wird unter Rühren zum Kochen erhitzt und  mehrere Stunden im Sieden belassen. Dann  wird filtriert, gewaschen und getrocknet.  



  In eine Mischung von<B>160</B> Teilen Brom  und<B>5000</B> Teilen Schwefelsäure werden unter    Rühren     und    Eiskühlung<B>380,5</B> Teile des so  erhaltenen Farbstoffes eingetragen. Nach       mehrstündigem    Rühren bei<B>6</B> 'bis<B>10'</B> wird       diie    Temperatur auf diejenige des Arbeits  raumes steigen gelassen und 12 Stunden wei  ter gerührt.     Naüb-    dieser Zeit ist das     Broni     verschwunden. Das     Reaktiunsprodukt    wird  auf Eis ausgetragen, der abgeschiedene Farb  stoff     filtriert,gewaschen    und getrocknet.



  Additional patent to main patent no. <B> 100705. </B> Process for the production of a new indigolden dye - It has been found that a new indigoid dye is obtained if the 2,3-thionaphthisatin (produced for example from 2, ä-Naphthtliioindoxyl by concentration with nitrosodimethylaniline and <B> separation </B> of ami-nodimethyli.niline from the aniline formed)

   condensed with <B> 6 - </B> chloroxythionnaphthalenecarboxylic acid and the crIraltene product brominated.



  The new dye is a purple powder that dissolves in sulfuric acid with a green color. With hydrosulfite and sodium hydroxide solution, it forms an orange-red vat and f-ii uses it to dye cotton in violet-red tones with very good fastness.



  <I> Example: </I> In <B> 5000 </B> parts of alcohol-214 parts are 2,3 <B> - </B> thional) htliisatin and <B> 22,5 </B> parts 6- Cliloroxythionaphthenecarboxylic acid entered. After adding <B> 5 </B> parts of ammonia, the mixture is heated to the boil while stirring and left at the boil for several hours. It is then filtered, washed and dried.



  In a mixture of 160 parts of bromine and 5000 parts of sulfuric acid, 380.5 parts of the dye thus obtained are introduced with stirring and ice cooling. After several hours of stirring at <B> 6 </B> 'to <B> 10' </B>, the temperature is allowed to rise to that of the working area and stirred for a further 12 hours. After this time the broni has disappeared. The reaction product is poured onto ice, and the deposited dye is filtered, washed and dried.
