  Zusatzpatent zum Hauptpatent     Nr.   <B>105939.</B>    Verfahren zur     Rerstellung    eines neuen     Chromierungsfarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Chromierungsfarbstoff    erhält, wenn man den  Farbstoff, welcher durch Kuppeln der ni  trierten     Diazoverbindung    der     1-Amino-2-oxy-          naphtha,lin-4-sulfosä,ure    mit     ss-Naphthol    ent  steht, mit reduzierend wirkenden Mitteln be  handelt.

   Als reduzierend wirkende Mittel  kommen hauptsächlich die     Sul.fide,        Sulf-          hydrate    und Polysulfide von Alkali- und       Erdalkalimetallen    in Betracht, oder andere  ähnlich wirkende Mittel, wie beispielsweise       Eisenoxydulhydrat        bezw.        -karbonat.     



  Der neue Farbstoff bildet ein schwarz  braunes Pulver, das sich in Wasser mit     vio-          lettbranner    Farbe löst, welche<B>auf</B> Zusatz  von-     Sodalösung    nach grünblau, auf Zusatz  von     Ätzkali        na,cli'blauviolett,    und auf Zusatz  von Säure nach rotbraun umschlägt. Er  färbt aus saurem Bade Wolle in rotvioletten       bezw.        braunschwarzen    Tönen an, welche  durch     Nachehromieren    grau     bezw.    schwarz  und sehr echt worden.

      <I>Beispiel<B>1:</B></I>  Eine möglichst konzentrierte Suspension  des Farbstoffes, erhalten durch Kuppeln von    46,5 Teilen     ss-Naphthol    mit<B>95</B> Teilen des       Natriumsalzes    der nitrierten     Diazoverbindung     der     1-A-mino-2-oxynaplithalin-4-sulfosäure,     enthaltend zirka<B>5</B> Teile     NaIriumkarbonat,     wird unter Rühren mit einer lauwarmen Lö  sung von<B>72</B> Teilen kristallisiertem Schwefel  natrium,<B>9,6</B> Teilen Schwefel, 12 Teilen     Na-          tronhydrat    und<B>58</B> Teilen Wasser versetzt  und hierauf einige Zeit     auf   <B>80</B> bis<B>90'</B> unter  weiterem Rühren erwärmt,

   wobei die zuerst       dickbreiige    Masse dünnflüssig wird.  



  Hierauf giesst man das Reaktionsprodukt  in Wasser, stumpft das überschüssige Alkali  mit Mineralsäure grösstenteils ab und scheidet  durch     Kochsalzzusatz    -den Farbstoff ab.  



  <I>Beispiel 2:</I>  Eine möglichst konzentrierte Suspension  des Farbstoffes, erhalten durch Kuppeln von  <B>150</B> Teilen     ss-Naplithcyl    mit<B>285</B> Teilen des       Natriumsalzes    der nitrierten     Diazoverhin-          dung    der     1-Amino-2-oxynaphthalin-4-sulio-          säure    wird unter Rühren mit einem geschmol  zenen Gemisch von<B>50</B> Teilen Wasser und  <B>360</B> Teilen     kristallisiertem    Schwefelnatrium  versetzt. Hierauf wird unter     stetein    Rühren      die Masse auf<B>75</B> bis<B>80 '</B> erwärmt, wobei  unter     Dünnflüssigwürden    Reaktion eintritt.

    Man rührt noch einige Zeit bei<B>80</B>     ',    verdünnt  mit 2     '/oiger    Kochsalzlösung und stumpft  sorgfältig das überschüssige Alkali mit Mi  neralsäure ab. Der     ausoeschiedene    Farbstoff  wird hierauf filtriert und getrocknet.



  Additional patent to main patent no. <B> 105939. </B> Process for the production of a new chromating dye. It has been found that a new chromating dye is obtained if the dye, which is formed by coupling the nitrated diazo compound of 1-amino-2-oxynaphtha, lin-4-sulfosä, ure with β-naphthol, with reducing effective means.

   As reducing agents are mainly the Sul.fide, sulfhydrate and polysulfide of alkali and alkaline earth metals into consideration, or other similarly acting agents, such as iron oxide sulfide or. -carbonate.



  The new dye forms a black-brown powder that dissolves in water with a violet-brown color, which <B> on </B> the addition of soda solution to green-blue, on the addition of caustic potash, cli'blue-violet, and on the addition of The acid turns reddish brown. He dyes from acidic bath wool in red-violet or. brown-black tones, which are gray or black and very real.

      <I> Example <B>1:</B> </I> A suspension of the dye which is as concentrated as possible, obtained by coupling 46.5 parts of ss-naphthol with 95 parts of the sodium salt of the nitrated diazo compound 1-A-mino-2-oxynaplithalin-4-sulfonic acid, containing about 5 parts of sodium carbonate, is mixed with a lukewarm solution of 72 parts of crystallized sodium sulphide while stirring. <B> 9.6 </B> parts of sulfur, 12 parts of sodium hydrate and <B> 58 </B> parts of water are added and then for some time to <B> 80 </B> to <B> 90 '< / B> heated while stirring,

   where the first thick pulpy mass becomes thin.



  The reaction product is then poured into water, most of the excess alkali is blunted with mineral acid and the dye is separated off by adding sodium chloride.



  <I> Example 2 </I> A suspension of the dye that is as concentrated as possible, obtained by coupling <B> 150 </B> parts of ss-naplithcyl with <B> 285 </B> parts of the sodium salt of the nitrated diazo compound the 1-amino-2-oxynaphthalene-4-sulioic acid is mixed with a molten mixture of <B> 50 </B> parts of water and <B> 360 </B> parts of crystallized sodium sulphide while stirring. The mass is then heated to <B> 75 </B> to <B> 80 '</B> with constant stirring, whereby a reaction occurs while being thin.

    The mixture is stirred for some time at <B> 80 </B> ', diluted with 2% sodium chloride solution and carefully blunted the excess alkali with mineral acid. The separated dye is then filtered and dried.
