Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde     gefunden,    dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          1-Amino    - 2 .     4-(4',4"-dichlor)-        diphenoxyben-          zol    mit. ,dem 2.     3-Oxynaphthoesäure-4'-chlor-          anilid    vereinigt.  



  Der neue Farbstoff bildet ein     rotes,    in  Wasser     unlösliches    Pulver. Auf geeigneten  Substraten, wie zum     Beispiel    Baumwolle,  hergestellt, färbt er diese in echten, roten  Tönen.  



       Beispiel;     34,6 Teile     1-Amino-2,4--(4',4"-dichlor)-di-          phenoxybenzol    werden wie üblich     diazotiert     und in eine Lösung von 29,7 Teilen     2,3-Oxy-          naphthoes.äure-4'-chloranilid,    40 Teilen 30 %     -          iger        Natriumhydroxydlösung,    15 Teilen    Soda und 2000 Teilen Wasser eingetragen.  Der gebildete Farbstoff fällt sofort aus.. Der  blaurote Niederschlag wird filtriert und ge  trocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized 1-amino-2. 4- (4 ', 4 "-dichlor) - diphenoxyben- zene combined with., The 2nd 3-oxynaphthoic acid-4'-chloroanilide.



  The new dye forms a red powder that is insoluble in water. Produced on suitable substrates such as cotton, he dyes them in real, red shades.



       Example; 34.6 parts of 1-amino-2,4- (4 ', 4 "-dichlor) -diphenoxybenzene are diazotized as usual and converted into a solution of 29.7 parts of 2,3-oxynaphthoic acid-4 '-chloranilide, 40 parts of 30% strength sodium hydroxide solution, 15 parts of soda and 2000 parts of water are added.The dye formed precipitates out immediately .. The blue-red precipitate is filtered and dried.
