Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 107394.    Verfahren zur     Herstellung    eines     Farbstoffes.       <B>Es</B> wurde gefunden, dass man einen  neuen Farbstoff erhält,. welcher in essig  saurem Bade eine überraschende Affinität       .zur        Acetylzellulose    -besitzt, wenn man di  <B>i</B>     azol        I        ierte        s        m-Nitranilin        mit        Benzylanilin-          sulfosäure    kuppelt.

   Der neue Farbstoff stellt  ein     gelboranges    Pulver dar und färbt     Ace-          tatseide    aus     essigsaurem    Bade echt gelb an.  <I>Beispiel:</I>  <B>138</B> Teile     m-Nitranilin    werden     diazotiert     und hierauf unter Rühren in eine Lösung von  <B>285</B> Teilen     benzylanilinsulfosaures    Natrium  gegossen. Man gibt dann allmählich     Soda-          L'       zu bis zur alkalischen Reaktion und  isoliert den gebildeten Farbstoff durch Aus  salzen und Filtrieren.



  <B> Additional patent </B> to main patent no. 107394. Process for the production of a dye. <B> It </B> has been found that one obtains a new dye. which in an acidic bath has a surprising affinity for acetyl cellulose when di-azole-iated s m -nitraniline is coupled with benzylaniline sulfonic acid.

   The new dye is a yellow-orange powder and stains acetate silk from acetic acid bath really yellow. <I> Example: </I> <B> 138 </B> parts of m-nitroaniline are diazotized and then poured into a solution of <B> 285 </B> parts of sodium benzylaniline sulfate with stirring. Soda-L 'is then gradually added until the reaction is alkaline and the dye formed is isolated by salting out and filtering.
