Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>152883.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass        man    einen neuen       Azofarbstoff    der Formel:  
EMI0001.0006     
    erhält, wenn man den     4.4'-Dichlor-2-diazo-          1   <B>.</B>     l'-diphenyläther    mit dem     p-Toluidid    der  2<B>.</B>     3-Oxynaphthoesäure    kuppelt.  



  Der so erhaltene Farbstoff bildet ein hell  rotes Pulver. Auf geeigneten Substraten, wie  zum Beispiel Baumwolle, hergestellt, färbt  er diese in leuchtenden, ausserordentlich  echten Tönen.  



  <I>Beispiel:</I>  2534 Teile 4.     4'-Dichlor-2-amino-1   <B>.</B>     l'-di-          phenyläther    werden wie üblich     diazotiert    und    in eine Lösung von<B>27,7</B> Teilen des     p-Tolui-          dids    der 2<B>.</B>     3-Oxynaphthoesäure,   <B>60</B> Teilen  <B>30</B>     "/Oiger    Natronlauge,<B>15</B> Teilen Soda und  2000 Teilen Wasser eingetragen. Der ge  bildete Farbstoff fällt sofort aus. Er wird  filtriert, gewaschen und getrocknet.



  Additional patent to main patent no. <B> 152883. </B> Process for the production of a new azo dye. It has been found that you can create a new azo dye of the formula:
EMI0001.0006
    obtained when the 4.4'-dichloro-2-diazo-1 <B>. </B> l'-diphenyl ether is coupled with the p-toluidide of 2 <B>. </B> 3-oxynaphthoic acid.



  The dye thus obtained forms a light red powder. Produced on suitable substrates, such as cotton, for example, he dyes them in bright, extraordinarily real tones.



  <I> Example: </I> 2534 parts of 4. 4'-dichloro-2-amino-1 <B>. </B> l'-diphenyl ethers are diazotized as usual and converted into a solution of <B> 27 , 7 </B> parts of the p-toluidide of 2 <B>. </B> 3-oxynaphthoic acid, <B> 60 </B> parts <B> 30 </B> "/ Oiger sodium hydroxide solution, < B> 15 parts of soda and 2000 parts of water are introduced, the dye formed precipitates immediately and is filtered, washed and dried.
