Description

  

      Zusatzpatent    zum Hauptpatent Nr. 114283.         Verfahren    zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen  neuen Farbstoff erhält, wenn man die  jenige     Phenylbarbitursäure,    welche aus       Plienylharnstof    f und     Malonester    erhalten       -wird,    mit     4-Chlor-2-amino-l-phenol-5-sulfo-          säure    kuppelt und das so erhaltene Produkt  mit     Fluorchrom    behandelt.

   Der neue Farb  stoff bildet ein braunes Pulver, löst sich in  verdünnter     Sodalösung    mit     orangegelber     Farbe und erzeugt auf Wolle, aus saurem  Bade gefärbt, echte rotorange Töne.  



  <I>Beispiel:</I>  24 Teile     4-Chlor-2-amino-l-phenol-5-          sulfosä.ure    werden wie üblich     diazotiert    und  in ein Gemisch aus 214 \feilen     Phenyl-          barbitursäure,    133 Teilen 30     %iger    Natron  lauge, 170 Teilen Soda und 1500 Teilen  Wasser eingetragen. Die Kupplung setzt so  fort ein, zu ihrer Vervollständigung rührt  man noch einige Zeit. Der gebildete Farb  stoff wird dann filtriert und getrocknet.  



  44,9 Teile dieses Farbstoffes werden in  650 Teilen kochendem Wasser gelöst und    mit einer     Fluorchromlösung,    entsprechend  15,2 Teilen     Cr203,    versetzt. Man kocht meh  rere Stunden am     Rückflusskühler,    dampft  teilweise ein und gewinnt die neue Chrom  verbindung durch Nitrieren, gegebenenfalls  unter vorherigem     Flussalzen.  



      Additional patent to main patent No. 114283. Process for the production of a new dye. It has been found that a new dye is obtained if the phenylbarbituric acid, which is obtained from plienylurea and malonic ester, is coupled with 4-chloro-2-amino-1-phenol-5-sulfonic acid and the resultant Product treated with fluorochrome.

   The new dye forms a brown powder, dissolves in a dilute soda solution with an orange-yellow color and creates real red-orange tones on wool dyed from an acid bath.



  <I> Example: </I> 24 parts of 4-chloro-2-amino-1-phenol-5-sulfonic acid are diazotized as usual and converted into a mixture of 214 parts phenylbarbituric acid and 133 parts of 30% strength sodium bicarbonate lye, 170 parts of soda and 1500 parts of water entered. The clutch continues in this way, and stir for a while to complete it. The color formed is then filtered and dried.



  44.9 parts of this dye are dissolved in 650 parts of boiling water and a fluorochrome solution, corresponding to 15.2 parts of Cr 2 O 3, is added. It is boiled for several hours on the reflux condenser, partially evaporated and the new chromium compound is obtained by nitriding, if necessary with prior flow salting.
