Description

  

      Zusatzpatent    zum Hauptpatent Nr. 114283.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man diejenige     p-Tolyl-          barbitursäure,    welche aus     p-Tolylharnstoff     und     Malonester    erhalten wird, mit dianotierter       4-Chlor-2-amino-l-phenol-6-sulfosäure    kuppelt  und das so erhaltene Produkt mit Fluor  chrom behandelt. Der neue Farbstoff bildet  ein oranges Pulver, löst sich in verdünnter       Sodalösung    mit oranger Farbe und erzeugt  auf Wolle, aus saurem Bade gefärbt, echte  rotorange Töne.  



  <I>Beispiel:</I>  224 Teile     4-Chlor-2-amino-l-phenol-6-          sulfosäure    werden wie üblich dianotiert und  in ein Gemisch von 228 Teilen     p-Tolyl-          barbitursäure,    133 Teilen     30o/oiger    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.    46,3 Teile dieses Farbstoffes werden in  650 Teilen kochendem Wasser gelöst und  mit einer     Fluorchromlösung    entsprechend 15,2  Teilen     Crs0a    versetzt.

   Man kocht mehrere  Stunden am     Rückflusskühler,    dampft teilweise  ein und gewinnt die neue Chromverbindung  durch Filtrieren, gegebenenfalls unter vor  herigem     Aussalzen.  



      Additional patent to the main patent No. 114283. Process for the production of a new dye. It has been found that a new dye is obtained if that p-tolylbarbituric acid, which is obtained from p-tolylurea and malonic ester, is coupled with dianotized 4-chloro-2-amino-1-phenol-6-sulfonic acid and that thus obtained product treated with fluorine chromium. The new dye forms an orange powder, dissolves in a dilute soda solution with an orange color and produces real red-orange tones on wool dyed from an acid bath.



  <I> Example: </I> 224 parts of 4-chloro-2-amino-1-phenol-6-sulfonic acid are dianotized as usual and mixed with 228 parts of p-tolylbarbituric acid and 133 parts of 30% sodium hydroxide solution , 170 parts of soda and 1500 parts of water entered. The clutch continues immediately; stir for a while to complete them. The color formed is then filtered and dried. 46.3 parts of this dye are dissolved in 650 parts of boiling water, and a fluorochrome solution corresponding to 15.2 parts of Crs0a is added.

   The mixture is boiled for several hours on the reflux condenser, partially evaporated and the new chromium compound is recovered by filtration, if necessary with salting out beforehand.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man diejenige p-Tolylbarbitursäure, welche aus p-Tolylharnstoff und Malonester erhalten wird, mit dianotierter 9.-Chlor-2-amino-l-phenol-6- sulfosäure kuppelt und das so erhaltene Pro dukt mit Flüorchrom behandelt. Der neue Farbstoff bildet ein oranges Pulver, löst sich in verdünnter Sodalösung mit oranger Farbe und erzeugt auf Wolle, aus saurem Bade gefärbt, echte rotorange Töne.
