Description

  

  Verfahren 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-caprinylaminobenzol    mit 1-(2',       chlorbenzoylamino)-8-oxynaphthalin-4.6-di-          sulfonsäure    vereinigt.  



  Der so erhaltene Farbstoff ist ein wasser  lösliches rotes Pulver und färbt Wolle aus  neutralem oder saurem Bade in leuchtenden  roten Tönen. Die     Färbungen    besitzen sehr  gute Echtheitseigenschaften.  



  <I>Beispiel:</I>  34,4 Teile     1-Amino    -4 -     N-Cyklohegyl-          caprinylaminobenzol    werden     diazotiert.    Die  erhaltene     Diazoverbindung    vereinigt man mit  einer     sodaalkalischen    Lösung von 50 Teilen  1- (2', 5'-Dichlorbenzoylamino)-8-ogynaphtba-         lin-4.6-disulfonsäure.    Der gebildete Farbstoff  wird abgeschieden und getrocknet.



  Process for the preparation 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-caprinylaminobenzene with 1- (2 ', chlorobenzoylamino) -8-oxynaphthalene-4,6 disulfonic acid combined.



  The dye obtained in this way is a water-soluble red powder and dyes wool from neutral or acid baths in bright red shades. The dyeings have very good fastness properties.



  <I> Example: </I> 34.4 parts of 1-amino -4 - N-cyclohegyl-caprinylaminobenzene are diazotized. The diazo compound obtained is combined with a soda-alkaline solution of 50 parts of 1- (2 ', 5'-dichlorobenzoylamino) -8-ogynaphtba- lin-4,6-disulfonic acid. The dye formed is deposited and dried.
