      Zusatzpatent    zum Hauptpatent     Nr.   <B>197690.</B>    Verfahren zur Darstellung eines     Chromierungsfarbstoffes.       Gegenstand dieses     Zugatzpatentes    ist ein  Verfahren zur Darstellung eines     Chromie-          rungsfarbstoffes,    welches dadurch gekenn  zeichnet ist,

       dass    man     5-Oxybenzol-1   <B>.</B> 2<B>-</B>     4-          trikarbonsäureanhydrid    mit     fl-Naphtodbinal-          din    kondensiert und das so erhaltene Pro  dukt mit einem     sulfierend    wirkenden Mittel  behandelt.  



  <I>Beispiel:</I>  20     Gewichtsteile        fl-Naphthochinaldin    von  der Formel:  
EMI0001.0016     
    21     Gewichtsteile        5-Oxytrimellithsäureanhy-          drid    und 14 Gewichtsteile Chlorzink werden  bei     220-230'   <B>0</B> bis zum Erstarren der  Schmelze verschmolzen. Die weitere Behand  lung der fein pulverisierten Schmelze ge  schieht durch Auskochen mit 200 Gewichts-         teilen        etwa        3%iger        Salzsäure,        Absaugen     des orangegelben     Niederschlages,    Waschen  und Trocknen.

   Nach dem     Umlösen    aus tech  nischem     Chinolin    wird der mit Alkohol ge  waschene und getrocknete gelbe, amorphe  Körper durch Erhitzen mit, der     15-fachen    Ge  wichtsmenge 20     1/oigem        Oleum    auf 120<B>0 C</B>  bis zur völligen Wasserlöslichkeit     sulfiert.     Die durch Eingiessen in Wasser und Absau  gen isolierte     Sulfosäure    wird durch     Aussal-          zen    aus der heissen     wässrigen    Lösung gereinigt.  



  Das so erhaltene Gemisch aus Mono- und       Disullosäure    ist ein gelbbraunes Pulver, das  Wolle und Seide gelb färbt und folgende  wahrscheinliche Konstitution besitzt-  
EMI0001.0038     




      Additional patent to main patent no. <B> 197690. </B> Process for the preparation of a chromating dye. The subject of this additional patent is a process for the preparation of a chromating dye, which is characterized by

       that 5-oxybenzene-1 <B>. </B> 2 <B> - </B> 4-tricarboxylic acid anhydride is condensed with fl-naphtodbinaldin and the product thus obtained is treated with a sulphurizing agent.



  <I> Example: </I> 20 parts by weight of fl-naphthoquinaldine of the formula:
EMI0001.0016
    21 parts by weight of 5-oxytrimellitic anhydride and 14 parts by weight of zinc chloride are fused at 220-230 '0 until the melt solidifies. The further treatment of the finely pulverized melt is done by boiling it with 200 parts by weight of about 3% hydrochloric acid, suctioning off the orange-yellow precipitate, washing and drying.

   After dissolving from technical quinoline, the yellow, amorphous body, washed with alcohol and dried, is sulfated by heating with 15 times the weight of 20 1 / o oleum to 120 ° C. until it is completely soluble in water . The sulfonic acid isolated by pouring it into water and sucking it off is purified from the hot aqueous solution by salting it out.



  The mixture of mono- and disulloic acid obtained in this way is a yellow-brown powder that dyes wool and silk yellow and has the following probable constitution-
