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       -ndense    l'acide     1-amino-4-bromanthraqui-          r        e-2,7-disulfonique    avec la     3-acétylamino-          4-méthylaniline.     



  Le colorant ainsi obtenu correspond à la  formule  
EMI0001.0011     
    et     teint    les     fibres    animales ou     animalisées    en       beaux    tons bleu     verdâtres    très solides.  



       Exemple:     On chauffe à 80  pendant 8     heures:     15 parties de     1-amino-4-bromanthraquinone-          2,7-disulfonate    de sodium, 9,9 parties de 3-         acétylamino-4-méthylaniline,    0,4     partie    de       sulfate    .de cuivre, 4,8 parties de bicarbonate  de     sodium,    75 parties d'eau et 5 parties d'al  cool.

   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:  
EMI0001.0030     
    et teint les fibres     animales    ou     animalisées    en  beaux tons bleu     verdâtres    très     solides.  



  Process for the preparation of 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 1-amino-4-bromanthraqui- r e-2,7-disulfonic acid is -ndenseed with 3 -acetylamino-4-methylaniline.



  The dye thus obtained corresponds to the formula
EMI0001.0011
    and dyes the animal or animal fibers in beautiful, very solid greenish blue tones.



       Example: Heated to 80 for 8 hours: 15 parts of sodium 1-amino-4-bromanthraquinone-2,7-disulfonate, 9.9 parts of 3-acetylamino-4-methylaniline, 0.4 part of sodium 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:
EMI0001.0030
    and dyes the animal or animal fibers in beautiful, very solid greenish blue tones.
