Description

  

  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 166223.    Verfahren zur Herstellung eines neuen     Anthrachinonderivates.       Es wurde gefunden, dass man ein neues       Anthrachinonderivat    erhält, wenn man 1-p  Oxyäthylamino-4-bromanthrachinon mit     1.4-          Diaminobenzol    umsetzt, wobei 1     Mol        1.4-Dia-          minobenzol    mit einem     Mol    des     Anthrachinon-          derivates    reagiert.  



  Der     Farbstoff    bildet ein dunkles Pulver,  löst sich in organischen     Lösungsmitteln    mit  grüner Farbe und färbt     Acetatseide    nach  geeigneter     Verpastung    in grünen Tönen.    <I>Beispiel:</I>  50 Teile     1-ss-Oxyäthylamino-4-bromanthra-          chinon    werden in 250 Teilen     Dimethylanilin     mit 75 Teilen     1.4-Diaminobenzol,    0,5 Teilen       Kupferchlorür    und 40 Teilen     galiumacetat     ca. 3     r/$    Stunden auf 110-120   erwärmt.

         Nan    fällt mit 350 Teilen Methylalkohol und    erhält in vorzüglicher Reinheit ein Produkt,  welches     Acetatseide    nach geeigneter     Verpa-          stung    in reinen, grünen Tönen färbt.



  <B> Additional patent </B> to main patent no. 166223. Process for the production of a new anthraquinone derivative. It has been found that a new anthraquinone derivative is obtained if 1-p oxyethylamino-4-bromoanthraquinone is reacted with 1,4-diaminobenzene, 1 mol of 1,4-diamino benzene reacting with one mole of the anthraquinone derivative.



  The dye forms a dark powder, dissolves in organic solvents with a green color and, after suitable pasting, dyes acetate silk in green tones. <I> Example: </I> 50 parts of 1-ss-oxyethylamino-4-bromanthraquinone in 250 parts of dimethylaniline with 75 parts of 1,4-diaminobenzene, 0.5 part of copper chloride and 40 parts of galium acetate are approx. 3 hours heated to 110-120.

         Nan falls with 350 parts of methyl alcohol and receives a product of excellent purity which, after suitable pasting, dyes acetate silk in pure, green tones.
