Description

  

  Zusatzpatent zum Hauptpatent     Nr.    100479.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    herstellen kann, wenn man die  nitrierte     Diazoverbindung    der     1-A-mino-2-          oxynaplitalin-4-suliosäure    mit     1-(3-Sulf-          amido)-phenyl-S-metliyl-5-pyrazolon    kuppelt.  Der neue     Azofarbstoff    bildet ein braunes  Pulver. Er färbt Wolle in braunen Farb  tönen, welche beim     Nach-chro-mieren    rot wer  den.  



  <I>Beispiel:</I>  <B>295</B> Teile der nitrierten     Diazoverbindung     der     1-Amino-2-oxynaphtalin   <B>-</B> 4<B>-</B>     sulfosäure     werden in eine abgekühlte Lösung von<B>253</B>  Teilen     1-(3"-SuIfami#do)-phenyl-3-methyl-5-          pyrazolon    in     30'/o-iger        Natranlange    einge  tragen. Nach einstündigem Rühren wird der  Farbstoff     #durch    schwaches     Ans#mern    mit    Mineralsäure aus der alkalischen Reaktions  flüssigkeit ausgefällt und gegebenenfalls     aus     Wasser umkristallisiert.



  Additional patent to main patent no. 100479. Process for the production of a new azo dye. It has been found that a new azo dye can be produced if the nitrated diazo compound of 1-A-mino-2-oxynaplitalin-4-sulioic acid with 1- (3-sulfamido) -phenyl-S-metliyl-5- pyrazolone couples. The new azo dye forms a brown powder. It dyes wool in brown shades, which turn red when it is re-chromed.



  <I> Example: </I> <B> 295 </B> parts of the nitrated diazo compound of 1-amino-2-oxynaphthalene <B> - </B> 4 <B> - </B> sulfonic acid are converted into a cooled solution of <B> 253 </B> parts of 1- (3 "-Sulfami # do) -phenyl-3-methyl-5-pyrazolone in 30% sodium length. After stirring for one hour, the dye # precipitated from the alkaline reaction liquid by weak acidification with mineral acid and optionally recrystallized from water.
