Description

  

  Verfahren zur Herstellung eines     Azofarbstoi%s.       Vorliegendes Patent bezieht sich auf ein       Verfahren    zur Herstellung eines     Azofarb-          stoffes,    dadurch gekennzeichnet, dass man die       Diazoverhindung    von     N-(3-Aminobenzoyl)-          N-,do        dekahydro    -     diphenyl-2'-methyl    -     phenyl-          amin    mit     1-(2',5'-Dimethyl-4'-chlorbenzol-          sulfoamino)    - 8     -ogynaphthalin-    3,

  6 -     disulfon-          säure    vereinigt.  



  Der so erhaltene Farbstoff ist trocken ein         rotes        Pulver,    dessen     lebhafte    rote Färbungen  auf Wolle sehr gute Echtheitseigenschaften,  insbesondere gegen Wäsche, Walke, Schweiss  und Seewasser, sowie gute Lichtechtheit be  sitzen.  



       Beispiel:     38,6 Teile     N-(3-Aminobenzoyl)-N-dodeka-          hydro    -     diphenyl-2'-methyl    -     phenylamin    der  Formel  
EMI0001.0025     
    werden     diazotiert    und die     Diazoverbindung     wird in     Gegenwart    von überschüssigem Ätz-         kalk    mit 53 Teilen     1-(2',5'-Dimethyl-4'-          chlorbenzol-sufoamino)-    8 -ogynaphthalin-3,6-           disulfonsäure    vereinigt.

   Der Farbstoff wird  dann in das     Natriumsalz    übergeführt und  dieses abgeschieden und getrocknet.



  Process for the production of an azo dye% s. The present patent relates to a process for the production of an azo dye, characterized in that the diazo compound of N- (3-aminobenzoyl) - N-, do decahydro - diphenyl-2'-methyl - phenyl amine with 1- ( 2 ', 5'-dimethyl-4'-chlorobenzenesulfoamino) - 8 -ogynaphthalene- 3,

  6 - disulfonic acid combined.



  The dyestuff thus obtained is a dry red powder, the vivid red colorations of which have very good fastness properties on wool, in particular against laundry, fulling, perspiration and seawater, and also good lightfastness.



       Example: 38.6 parts of N- (3-aminobenzoyl) -N-dodecahydro-diphenyl-2'-methyl-phenylamine of the formula
EMI0001.0025
    are diazotized and the diazo compound is combined with 53 parts of 1- (2 ', 5'-dimethyl-4'-chlorobenzene-sufoamino) -8 -ogynaphthalene-3,6-disulfonic acid in the presence of excess quicklime.

   The dye is then converted into the sodium salt, which is deposited and dried.
