Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoifes.            Esi        wurde        gefunden"dass@    man einen neuen       A,zofarbstoff    erhält, wenn     man        diazotiertes          3-Amino-phthalsäure-N-äthyl-imid,        mit    :dem       2,3-Ogynaphthoesäure    - 2' -     methogy    -     ä'-        chlor-          anilid        vereinigt.     



  Der neue Farbstoff bildet ein rotes, in  Wasser unlösliches Pulver. Auf geeigneten       Substraten,-    wie z. B. Baumwolle, hergestellt,  färbt er diese in echten, scharlachroten Tönen.         Beispiel:     19 Teile des     3-Amino-phthalsäure-N-          äthyl-imids    werden wie üblich     diazotiert     und in     eine        Lösung    von 32,7 Teilen     2,3-Ogy-          naphthoesäure-2'-methogy-5'-chloranilid,    40  Teilen 30%iger     Natriumhydrogydlösung,    15  Teilen Soda in 1000 Teilen Wasser eingetra-    gen. Der gebildete Farbstoff fällt sofort aus.

    Der scharlachrote Niederschlag wird filtriert  und getrocknet.



  Process for the production of a new azo dye. It has been found that a new A, zo dye is obtained if diazotized 3-amino-phthalic acid-N-ethyl-imide is combined with: 2,3-ogynaphthoic acid - 2 '- methogy - a'-chloroanilide .



  The new dye forms a red powder that is insoluble in water. On suitable substrates - such as. B. Cotton, he dyes them in real, scarlet tones. Example: 19 parts of 3-aminophthalic acid-N-ethyl-imide are diazotized as usual and poured into a solution of 32.7 parts 2,3-ogynaphthoic acid-2'-methogy-5'-chloroanilide, 40 parts 30 % strength sodium hydrogen solution, 15 parts of soda in 1000 parts of water. The dye formed precipitates immediately.

    The scarlet precipitate is filtered and dried.
