Description

  

      Brevet     subordonné au brevet principal ne 236390.    Procédé de préparation d'un nouveau colorant de la série     anthraquinonique.            Le    présent brevet a pour objet un     -procédé     de     préparation    d'un nouveau colorant -de la  série     anthraquinonique,    selon lequel on     con-          -dense    l'acide     1-amino-4-bromanthraquinone-          2,7-disulfonique    avec la     3-acétylamino-4-          (méthylcarboxy)    -aniline.  



  Le colorant ainsi obtenu correspond à la  formule  
EMI0001.0013     
    et     teint    la laine et les. fibres animales en  beaux     tons    bleu verdâtres.  



       Exemple:     On chauffe à 80  pendant 8 heures:  15 parties de l.-amino-4-bromanthraquinone-         2,7-,disulfonate    de .sodium, 8,4'     parties    de  3 -     acétylamino    - 4 -     (méthylcarboxy)    - aniline, .  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 conden  sation     terminée,    on coule la masse dans de  l'eau acidulée et on essore le colorant qui  s'est séparé.  



  Le colorant     ainsi    obtenu     -correspond    à la       formule     
EMI0001.0027     
    et teint la laine et les fibres animales en  beaux tons bleu verdâtres.



      Patent subordinate to main patent no 236390. Process for preparing a new dye of the anthraquinone series. The present patent relates to a -process for the preparation of 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- (methylcarboxy) -aniline.



  The dye thus obtained corresponds to the formula
EMI0001.0013
    and dyed wool and them. animal fibers in beautiful greenish blue tones.



       Example: Heated at 80 for 8 hours: 15 parts of 1-amino-4-bromanthraquinone-2,7-, sodium disulfonate, 8.4 'parts of 3-acetylamino - 4 - (methylcarboxy) - aniline, . 0.4 part of copper sulphate, 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.



  The dye thus obtained corresponds to the formula
EMI0001.0027
    and dyes wool and animal fibers in beautiful greenish blue tones.
