      Zusatzpatent    zum Hauptpatent Nr. 232121.    Verfahren zur Herstellung eines     Harnstoffderivates.       Es     wurde        gefunden;,        da,Z        man    zu     einem          neuen        Harnstof    f     derivat        gelangt,    das gleich  zeitig     einen        wertvollen        Azofarbstoff    darstellt,  wenn     mann    auf 1     Mol        der        2-Methyl-4-,

  Der neue Farbstoff stellt     ein,    hellbraunes  Pulver dar, das     Baumwolle    in schwach alka  lischem     Bade"da@s    mit einer     Kupfersalzlösung     aus     Kupfersulfat    und     weinsaurem        Natrium          versetzt    wurde, in     waschechtem        ;grüns:tichig     gelbem     Tone    ;anfärbt.

           Beispiel:       38,1     Gewichtsteile    des     MonoazoTarbstoffes     aus     @diazotierter        1-Amino-4-oxybenzal-3-carb-          oxy-5@sulfo@nsäure    und     1-Methyl-3-amino-4-          methoxybernzal        werden:    als     Na-Salz        unter    Zu  satz von 13,5     Gewichtsteilen        Natriumacetat     in 250 Gewichtsteilen "Wasser gelöst.

   Diese  Lösung wird bei etwa 60      mit        18.,5    Gewichts-         teilen        4-Nit:robenzoy        lchlorid,    die mit 5 Ge  wichtsteilen     Aceton        versetzt        wurden:

      Additional patent to main patent no. 232121. Process for the production of a urea derivative. It has been found that, Z one arrives at a new urea derivative, which at the same time represents a valuable azo dye, if one mole of the 2-methyl-4-,

  (4 "- amino) -benzoylanvuso, -5-metho @ xy-4'-oxy-1,1'-azobenzene-3'-carbo @ nic acid-5'-sulfonic acid and 1 mol 4- (4" - Amino) -b @ enz.oylamino, -4'-oxy-1,1'-azobenzal-3'-carbonic acid allows 1 mol of phosgene to act.



  The new dye is a light brown powder which cotton in a weakly alkaline bath has been mixed with a copper salt solution of copper sulfate and tartrate of sodium in a washable, green: tinged yellow shade.

           Example: 38.1 parts by weight of the monoazo dye from @diazotized 1-amino-4-oxybenzal-3-carbo-oxy-5 @ sulfonic acid and 1-methyl-3-amino-4-methoxybenzal are: as Na salt under Zu set of 13.5 parts by weight of sodium acetate dissolved in 250 parts by weight of water.

   This solution is at about 60 with 18., 5 parts by weight of 4-Nit: robenzoy lchloride, to which 5 parts by weight of acetone were added:

  , treated. The nitrobenzoyl product formed is reduced with 42 parts by weight of crystallized sodium sulfide, which were dissolved in 75 parts by weight of water, at 65 to 70 to the aminobenzoyl product. The separated reduction product is mixed with 37.6 parts by weight of 4- (4 "-amino) -benzoylamino-4'-o # xy-1,

  1-azoben-zol-3'-oaronic acid with the addition of sodium carbonate until a distinct alkaline reaction was found in 4000 parts by weight of Wasis: dissolved and treated with phosgene for 24 hours while stirring at 30 = .40 until no free NH2 group allows more evidence. That:

  The unsymmetrical urea derivative precipitated is precipitated as sodium salt, filtered and dried.
