Description

  

      Verfabren    zur Herstellung eines     Azofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Azofarb-          stoffes,    dadurch gekennzeichnet, dass man die       Diazoverbindung    von     1-Amino-4-N-cyklo-          hexyl-cyklohexylproprionylaminobenzol    mit       1-(2'-5'-Dichlorbenzoylamino)    - 8 -     oxynaphtha-          lin-4.6-disulfonsäure    vereinigt.  



  Der so erhaltene     Farbstoff    ist ein rotes,  wasserlösliches Pulver und färbt Wolle oder  Seide aus neutralem Bade in leuchtend roten  Tönen von sehr guter Wasch-,     Walk-,    Schweiss-,  Seewasser- und Lichtechtheit.  



  <I>Beispiel:</I>  32,6 Teile     1-Amino-4-N-cyklohexyl-cyklo-          hexylpropionilaminobenzol    werden     diazotiert.     Die erhaltene     Diazoverbindung    vereinigt man  mit einer     sodaalkalischen    Lösung von 5Q  Teilen 1-(2'.5'-Dichlorbenzoylamino)-8-oxy-         naphtbalin-4.6-disulfonsäure.    Der gebildete  Farbstoff wird abgeschieden und getrocknet.



      Procedure for the production of an azo dye. The present patent relates to a process for the production of an azo dye, characterized in that the diazo compound of 1-amino-4-N-cyclohexyl-cyclohexylproprionylaminobenzene with 1- (2'-5'-dichlorobenzoylamino) - 8 - oxynaphthalin-4,6-disulfonic acid combined.



  The dye obtained in this way is a red, water-soluble powder and dyes wool or silk from a neutral bath in bright red shades of very good fastness to washing, fulling, perspiration, seawater and light.



  <I> Example: </I> 32.6 parts of 1-amino-4-N-cyclohexyl-cyclohexylpropionilaminobenzene are diazotized. The diazo compound obtained is combined with a soda-alkaline solution of 50 parts of 1- (2'.5'-dichlorobenzoylamino) -8-oxynaphthalene-4,6-disulfonic acid. The dye formed is deposited and dried.
