Description

  

      Verfahren    zur Herstellung eines     illonoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Monoazo-          farbstoffes,    dadurch gekennzeichnet, dass man  die     Diazoverbindung    von     1-Aminobenzol-3-          carbonsäure    - C     -cy        klohexyl        -C-phenyl-methyl-          amid    mit 1- (2'-     Chlorphenoxyacetylamino)        -          8-oxynaphthalin-4,6-disulfonsäure    vereinigt.  



  Der so erhaltene Farbstoff ist getrocknet  ein wasserlösliches rotes Pulver und färbt    Wolle in lebhaften     gelbstichigen        Rottönen     von sehr guter Echtheit, insbesondere gegen  Wäsche, Walke, Schweiss, Seewasser und  Licht.  



  <I>Beispiel:</I>  Die wie übliche hergestellte     Diazoverbin-          dung    aus 30,8 Teilen     1-Aminobenzol-3-car-          bonsäure-C-cyklohexyl-C-pheny        1-methylamid     der Formel:  
EMI0001.0022     
    wird in     sodaalkalischer    Lösung mit 49 Teilen  1- (2'-     Chlorphenoxyacetylamino)        -8-oxynaph-          thalin-4,6-disulfonsäure    vereinigt. Nach be  endeter Kupplung wird der Farbstoff ab  geschieden und getrocknet.



      Process for the production of an illonoazo dye. The present patent relates to a process for the production of a monoazo dye, characterized in that the diazo compound of 1-aminobenzene-3-carboxylic acid - C -cyclohexyl -C-phenyl-methyl-amide with 1- (2'-chlorophenoxyacetylamino ) - 8-oxynaphthalene-4,6-disulfonic acid combined.



  The dyestuff obtained in this way is a water-soluble red powder when dried and dyes wool in vivid yellow-tinged red shades of very good fastness, especially to laundry, fulling, sweat, seawater and light.



  <I> Example: </I> The diazo compound produced as usual from 30.8 parts of 1-aminobenzene-3-carboxylic acid-C-cyclohexyl-C-pheny 1-methylamide of the formula:
EMI0001.0022
    is combined in a soda-alkaline solution with 49 parts of 1- (2'-chlorophenoxyacetylamino) -8-oxynaphthalene-4,6-disulfonic acid. After coupling has ended, the dye is separated off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Mono azofarbstoffes, dadurch gekennzeichnet, dass man die Diazoverbindung von 1-Amino benzol-3-carbonsäure-C-cyklohexyl-C-phenyl- methylamid mit 1-(29'-Chlorphenoxyacetyl- amino) -8- oxynaphthalin --1,6 - disulfonsäure vereinigt. PATENT CLAIM: A process for the production of a mono azo dye, characterized in that the diazo compound of 1-aminobenzene-3-carboxylic acid-C-cyclohexyl-C-phenylmethylamide with 1- (29'-chlorophenoxyacetylamino) -8-oxynaphthalene --1,6 - disulfonic acid combined. Der so erhaltene Farbstoff ist getrocknet ein wasserlösliches rotes Pulver und färbt Wolle in lebhaften gelbstichigen Rottönen von sehr guter Echtheit, insbesondere gegen Wäsche. Walke, Schweiss, Seewasser und Licht. The dye thus obtained is a water-soluble red powder when dried and dyes wool in vivid yellow-tinged red tones of very good fastness, in particular to laundry. Walk, sweat, sea water and light.
