Description

  

  Verfahren zur Herstellung eines neuen     Monoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen Mono  azofarbstoffes, dadurch gekennzeichnet, dass  man die     Diazoverbindung    des     1-Methoxy-          acetyl-cyclohexylamino-4-aminobenzols    mit       1-(2'-Chlor-5'-sulfophenyl)-3-methyl-5-pyrazo-          lon    kuppelt.  



  Der erhaltene Farbstoff stellt ein gelbes,  wasserlösliches Pulver dar und färbt die  animalische Faser in egalen     grünstichig    gel  ben Tönen von sehr guter Wasch-,     Schweiss-          und    Lichtechtheit.  



  <I>Beispiel:</I>  26,2 kg     1-Methoxyaeetyl-cyclohexylamino-          4-aminobenzol    werden in üblicher Weise  dianotiert und die erhaltene     Diazolösung     wird mit einer     sodaalkalischen    Lösung von       28        kg        des        1-(2'-Chlor-5'-sulfophenyl)-3-r        ethyl.            5-pyrazolons    gekuppelt. Der gebildete Farb  stoff wird in üblicher Weise isoliert und  getrocknet.



  Process for the preparation of a new monoazo dye. The present patent relates to a process for the preparation of a new mono azo dye, characterized in that the diazo compound of 1-methoxyacetyl-cyclohexylamino-4-aminobenzene with 1- (2'-chloro-5'-sulfophenyl) -3- methyl-5-pyrazolone couples.



  The dye obtained is a yellow, water-soluble powder and dyes the animal fibers in level greenish yellow shades of very good fastness to washing, perspiration and light.



  <I> Example: </I> 26.2 kg of 1-methoxyaeetyl-cyclohexylamino-4-aminobenzene are dianotized in the usual way and the diazo solution obtained is mixed with a soda-alkaline solution of 28 kg of 1- (2'-chloro-5 ' -sulfophenyl) -3-r ethyl. 5-pyrazolones coupled. The color formed is isolated and dried in the usual way.
