Description

  

  Procédé de préparation d'un nouveau colorant de la série     anthraquinonique.       Le présent brevet a pour objet un pro  cédé de préparation d'un nouveau colorant  de la     série        anthraquinonique,    selon lequel on  condense l'acide     1-amino-4-bromanthraqui-          none-2,7=disulfonique    avec la     3-acétylamino-          4-chloraniJine.     



  Le colorant ainsi obtenu correspond à la  formule  
EMI0001.0008     
    et teint les     fibres    animales ou     animalisées    en  beaux tons bleu verdâtres.     très    solides.  



  <I>Exemple:</I>  On chauffe à 80  pendant 8 heures:  15 parties de     1-amino-4-bromanthraquinone-          M   <B>1)</B>       -disulfonate    de sodium, 10,5 parties de         3-acétylamino-4-chloraniline,    0,4     partie        @de          sulfate,de    cuivre, 4,8 parties de bicarbonate  de sodium, 75 parties d'eau et 5     parties          d'alcool.    La     masse,de    réaction     passe,du    rouge  au bleu verdâtre.

   La     condensation        terminée,     on coule la masse -dans de l'eau acidulée et  on essore le colorant qui s'est séparé. Celui-ci  correspond à la formule     suivante:     
EMI0001.0026     
    et teint     les    fibres.     animales    ou     animalisées    en  beaux     tone    bleu     verdâtres    très solides.



  Process for the preparation of a new dye of the anthraquinone series. The present patent relates to a process for preparing a novel dye of the anthraquinone series, according to which the 1-amino-4-bromanthraquinone-2,7 = disulfonic acid is condensed with 3-acetylamino-4 -chloraniJine.



  The dye thus obtained corresponds to the formula
EMI0001.0008
    and dyes animal or animal fibers in beautiful greenish blue tones. very solid.



  <I> Example: </I> Heated at 80 for 8 hours: 15 parts of 1-amino-4-bromanthraquinone- M <B> 1) </B> -sodium disulphonate, 10.5 parts of 3- acetylamino-4-chloraniline, 0.4 part of sulfate, copper, 4.8 parts of sodium bicarbonate, 75 parts of water and 5 parts of alcohol. The reaction mass changes from red to greenish blue.

   When the condensation is complete, the mass is poured into acidulated water and the dye which has separated is filtered off. This corresponds to the following formula:
EMI0001.0026
    and dyed the fibers. animal or animalized in beautiful greenish blue tones very solid.
