Description

  

      Zumsatzpatent    zum Hauptpatent     Nr.    161842.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen     Azofarbstoff    der Formel:  
EMI0001.0006     
    erhält, wenn man den     Phenylester    des     2-Di-          azo        z        -4-karbonsätire-1.1'-dipbenyläthers        mit     dem     Anilid    der 2.     S-Oxynaphtoesäure    kuppelt.  Der so erhaltene Farbstoff bildet ein rotes  Pulver.

   Auf geeigneten Substraten, wie zum  Beispiel Baumwolle, Wolle, Kunstseide her  gestellt, färbt er diese in leuchtenden, sehr  echten scharlachroten Tönen.    <I>Beispiel:</I>       30,5    Teile     Phenylester    des     2-Amino-4-          karbonsäure-1   <B>.</B>     l'-dipheiiyläthers    werden wie    üblich     diazotiert    und in eine Lösung von  <B>26,3</B> Teilen des     Anilids    der     2.3-Oxynaphtoe-          säure,

          60        Teilen        30        %iger        Natriumhydroxyd-          lösung,   <B>16</B> Teilen Soda und 2000 Teilen  Wasser eingetragen. Der gebildete Farbstoff  fällt sofort aus.<B>Er</B> wird filtriert, gewaschen  und getrocknet.



      Supplementary patent to main patent no. 161842. 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 phenyl ester of 2-di-azo z -4-carbonate-1.1'-dipbenyl ether is coupled with the anilide of 2. S-oxynaphtoic acid. The dye thus obtained forms a red powder.

   Produced on suitable substrates, such as cotton, wool or rayon, he dyes them in bright, very real scarlet shades. <I> Example: </I> 30.5 parts of phenyl ester of 2-amino-4-carboxylic acid-1 <B>. </B> l'-Dipheiiyläthers are diazotized as usual and in a solution of <B> 26, 3 </B> parts of the anilide of 2,3-oxynaphthoic acid,

          60 parts of 30% sodium hydroxide solution, 16 parts of soda and 2000 parts of water are added. The dye formed precipitates immediately. <B> It </B> is filtered, washed and dried.
