Description

  

  Verfahren zur Herstellung eines     Nonoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Morroazo-          farbstoffes,    dadurch gekennzeichnet, dass man  dianotiertes     p-Aminobenzoyl    -     di    -     cyclohexyl-          amin    in     sodaalkalisehem    Medium mit     1-(2'-          Chlor-pherioxy-acetylamino)-8    -     naphthol    - 4 .     6-          disulfosäure    kuppelt.  



  Der neue Farbstoff stellt nach dem Trock  nen ein rotes wasserlösliches Pulver dar und  färbt Wolle und Seide in leuchtend roten  Tönen von sehr guter     Walk-.    Schweiss- und  Lichtechtheit.  



  <I>Beispiel:</I>  Eine wie üblich aus 30 Teilen     p-Amino-          benzoyl-di-cyclohexylamin    hergestellte     Diazo-          lösung    wird in Gegenwart von Soda mit 49  Teilen     1-(2'-Chlor-phenogy-acetylamino)-8-          naphthol    - 4. 6 -     disulfosäure    gekuppelt. Nach    beendeter Kupplung wird der     Farbstoff    iso  liert und getrocknet.



  Process for the preparation of a nonoazo dye. The present patent relates to a process for the preparation of a Morroazo dye, characterized in that dianotated p-aminobenzoyl - di - cyclohexylamine in a soda-alkaline medium with 1- (2'-chloro-pherioxy-acetylamino) -8 - naphthol - 4th 6- disulfonic acid couples.



  After drying, the new dye is a red, water-soluble powder and dyes wool and silk in bright red tones of very good fulling. Sweat and light fastness.



  <I> Example: </I> A diazo solution prepared as usual from 30 parts of p-aminobenzoyl-di-cyclohexylamine is mixed with 49 parts of 1- (2'-chloro-phenogy-acetylamino) -8 in the presence of soda - naphthol - 4. 6 - disulfonic acid coupled. After the coupling has ended, the dye is isolated and dried.
