Description

  

  Zusatzpatent zum     Hauptpatent        Nr,    161841.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen     Azofarbstoff    der Formel:  
EMI0001.0005     
    erhält, wenn man den     2-Diazo-4.4'-dimeth-          oxy-5-acetylamirio-1.1'-diphetiyläther    mit dem       p-Anisidid    der 2.     3-Oxy        )aphtoesäure    kuppelt.  



  Der so erhaltene     Farbstoff    bildet ein rot  violettes Pulver. Auf geeigneten Substraten,  wie zum Beispiel Baumwolle, Wolle, Kunst  seide, hergestellt, färbt er diese in leuchten  den, sehr echten violetten Tönen.    <I>Beispiel:</I>  30,2 Teile     2-Amino-4.4'-dirnethoxy-5-aee-          tylamino-1.1'-diphenyläther    werden wie    üblich     diazotiert    und in eine Lösung von 29,3  Teilen des     p-Anisidids    der 2.     3-Oxynaphtoe-          säure,    60 Teilen 30     o/oiger        Natriumhydroxyd-          lösung,    15 Teilen Soda und 2000 Teilen  Wasser eingetragen.

   Der gebildete Farbstoff  fällt sofort aus. Er wird filtriert, gewaschen  und getrocknet.



  Additional patent to main patent no. 161841. Process for the production of a new azo dye. It has been found that you can create a new azo dye of the formula:
EMI0001.0005
    obtained when the 2-diazo-4.4'-dimethoxy-5-acetylamirio-1.1'-diphetiyl ether is coupled with the p-anisidide of the 2. 3-oxy) aphtoic acid.



  The dye thus obtained forms a red-violet powder. Produced on suitable substrates such as cotton, wool, artificial silk, he dyes them in bright, very real purple tones. <I> Example: </I> 30.2 parts of 2-amino-4.4'-dirnethoxy-5-aetylamino-1.1'-diphenyl ether are diazotized as usual and converted into a solution of 29.3 parts of the p-anisidide 2. Entered 3-oxynaphthoic acid, 60 parts of 30% sodium hydroxide solution, 15 parts of soda and 2000 parts of water.

   The dye formed precipitates immediately. It is filtered, washed and dried.
