Description

  

  Verfahren zur Herstellung eines     Farbstoffes.            anilinsulfosaures    Natrium gegossen. Die     Farb-          stoffbildung    geht sehr rasch vor sich, und,  sobald die     Diazoverbindung    verschwunden ist,  wird der Farbstoff filtriert und     getrocknet.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, welcher in essigsaurem Bade  eine überraschende Affinität zur     Acetylzellu-          lose    besitzt, wenn man     diazotiertes        2,

  4-Di-          nitranilin    mit     Äthylbenzylanilinstrlfosäui@e     kuppelt. Der neue     Farbstoff    stellt ein     bron-          zierendes    Pulver dar und färbt     Acetatseide     aus essigsaurem Bade echt blaurot an.  



  <I>Beispiel</I>  183 Teile     2,4-Diiritraiiiliti    werden durch  Eintragen in eine Lösung der berechneten  Menge     Nitrosylsulfat    in konzentrierter Schwe  felsäure in die     Diazoverbindung    übergeführt  und die Mischung auf Eis gegossen. Die Re  aktionsflüssigkeit wird hierauf unter Rühren  in eine Lösung von 313 Teilen äthylbenzyl-



  Process for the preparation of a dye. Poured sodium aniline sulfate. The dye formation is very rapid and once the diazo compound has disappeared the dye is filtered and dried. It has been found that a new dye is obtained which has a surprising affinity for acetylcellulose in an acetic acid bath when diazotized 2,

  4-di-nitraniline couples with ethylbenzylaniline sulfosäui @ e. The new dye is a bronzing powder and stains acetate silk from an acetic acid bath in a real blue-red color.



  <I> Example </I> 183 parts of 2,4-diiritraiiiliti are converted into the diazo compound by adding the calculated amount of nitrosyl sulfate in concentrated sulfuric acid to a solution and the mixture is poured onto ice. The reaction liquid is then added to a solution of 313 parts of ethylbenzyl while stirring
