Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes     4-     (4'-Methyl)-phenoxyacetylamino-2.5-diäth-          oxy-l-aminobenzol    mit dem     2-Oxy-2'-(4"-          chlor)-phenyl-5.6-pseudonaphthazimid    ver  einigt.  



  Der neue Farbstoff bildet ein braunes, in  Wasser unlösliches Pulver. Auf geeigneten  Substraten, wie z. B. Baumwolle, hergestellt,  färbt er diese in echten braunen Tönen.    <I>Beispiel:</I>    34,4 Teile des     4-(4'-11Iethyl)-phenoxy-          acetylamino    -<B>2.5</B> -     diäthoxy    -1-     aminobenzols     werden wie üblich     diazotiert    und in eine  Lösung von 29,5 Teilen     2-Oxy-2'-(4"-chlor)-          phenyl-5.6-pseudonaphthazimid,    40 Teilen  30%iger     Natriumhydroxydlösung,    15 Tei-         len    Soda     in    1000 Teilen Wasser eingetragen.

    Der gebildete Farbstoff fällt sofort aus.  Der braune Niederschlag wird filtriert und       getrocknet.  



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained when diazotized 4- (4'-methyl) -phenoxyacetylamino-2.5-diet-oxy-l-aminobenzene with the 2-oxy-2 '- (4 "- chlorine) - phenyl-5.6-pseudonaphthazimide united.



  The new dye forms a brown powder that is insoluble in water. On suitable substrates, such as. B. Cotton, he dyes them in real brown tones. <I> Example: </I> 34.4 parts of 4- (4'-11Iethyl) -phenoxy-acetylamino - <B> 2.5 </B> - diethoxy -1-aminobenzene are diazotized as usual and converted into a solution of 29.5 parts of 2-oxy-2 '- (4 "-chlor) - phenyl-5,6-pseudonaphthazimide, 40 parts of 30% strength sodium hydroxide solution, 15 parts of soda in 1000 parts of water were added.

    The dye formed precipitates immediately. The brown precipitate is filtered off and dried.
