Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,. dass man einen neuen  Farbstoff erhält,     -wenn    man     Barbitursäure     mit dianotierter     4-Sulfo-2-amino-l-phenol-fi-          karbonsäure        kuppelt.    Der neue Farbstoff  bildet ein oranges Pulver, löst sich in Was  ser auf Zusatz von     Sodalösung    mit gelb  oranger Farbe und färbt Wolle aus saurem  Bade in gelben Tönen, die beim     Nachebro-          mieren    braungelb und echt werden.  



  <I>Beispiel:</I>  233 Teile     4-Sulfo-2-amino-l-phenol-6-          karbansäure    werden wie üblich dianotiert  und in ein Gemisch aus 134 Teilen     Barbitur-          säure,    133 Teilen 30     %iger    Natronlauge, 170  Teilen Soda und 1500 Teilen Wasser     ein-          hetragen.    Die     Kupplung    setzt sofort ein, zu    ihrer Vervollständigung rührt man noch  einige Zeit. Der gebildete Farbstoff     wird     dann filtriert und getrocknet.



  Process for the production of a new dye. It was found,. that a new dye is obtained if barbituric acid is coupled with dianotated 4-sulfo-2-amino-1-phenol-ficarboxylic acid. The new dye forms an orange powder, dissolves in water with the addition of soda solution with a yellow-orange color and dyes wool from acid baths in yellow tones, which become brown-yellow and real when they are rebrowned.



  <I> Example: </I> 233 parts of 4-sulfo-2-amino-1-phenol-6-carbanic acid are dianotized as usual and converted into a mixture of 134 parts of barbituric acid, 133 parts of 30% sodium hydroxide solution, 170 parts Soda and 1500 parts of water are introduced. The clutch works immediately, and stir for some time to complete. The dye formed is then filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man Barbitursäure mit dianotierter 4-Sulf o- 2-amino-l-phenol-6-karbonsäure kuppelt. Der neue Farbstoff bildet ein oranges Pulver, löst sich in Wasser auf Zusatz von Soda lösung mit gelboranger Farbe- und färbt Wolle aus saurem Bade in gelben Tönen, die beim Nachchromieren braungelb und echt werden. PATENT CLAIM: Process for the production of a new dye, characterized in that barbituric acid is coupled with dianotated 4-sulfo-2-amino-1-phenol-6-carboxylic acid. The new dye forms an orange powder, dissolves in water with the addition of soda solution with a yellow-orange color and dyes wool from acidic baths in yellow tones, which become brown-yellow and real when chromium-plating.
