Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>152883.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    der Formel:  
EMI0001.0005     
    erhält,     #venn    man den 4.     2'-Dichlor-2-diazo-          1        l'-diphenyläthei-    mit dein     p-Phetietidid    der  2     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>  25,4 Teile 4.     2'-Dichlor-2-amino-1   <B>.</B>     l'-di-          phenyläther    werden wie üblich     diazotiert    und    in eine Lösung von<B>30,2</B> Teilen des     p-Pheiie-          tidids    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 was found that a new azo dye of the formula:
EMI0001.0005
    obtained #venn the 4th 2'-dichloro-2-diazo-1 l'-diphenyläthei- with the p-Phetietidid of 23-oxynaphthoic acid coupled.



  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> 25.4 parts of 4. 2'-dichloro-2-amino-1 <B>. </B> l'-diphenyl ethers are diazotized as usual and converted into a solution of <B > 30.2 </B> parts of the p-phenidide of the 2 <B>. </B> 3-oxynaphthoic acid, <B> 60 </B> parts <B> 30 </B> '/ o sodium hydroxide solution , <B> 15 </B> parts of soda and 2000 parts of water. The dye formed precipitates out immediately. It is filtered, washed and dried.
