Description

  

  Procédé de préparation d'un nouveau colorant de la série     anthraquinonique.       La présente invention 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-chloranthraqui-          none-2,6--disulfonique    avec l'acide     m-amino-          benzoïque.     



       Le    nouveau colorant correspond à la f     or-          mule        suivante:     
EMI0001.0014     
    et teint les fibres animales en bleu     rougeâtre,     ne virant pas à ,la lumière artificielle.  



       Exemple:     On prépare la solution suivante: 5,6 par  ties d'acide     m-aminobenzoïque    et 60 parties  d'eau, on neutralise par 3,2 parties de soude    et on ajoute 13     parties    de     1-amino-4-chlor-          anthraquinone-2,6-disulfonate    de sodium et  0,2     partie    de poudre de cuivre et chauffe à  80  jusqu'à     ce    que la condensation soit termi  née. On nettoie le colorant par     adjonction    de  sel qui le précipite, et filtre.

   Le nouveau colo  rant correspond à la formule    et     teint    les fibres     animales    en bleu rougeâtre,  ne virant pas à la lumière artificielle.



  Process for the preparation of a new dye of the anthraquinone series. The present invention relates to a process for the preparation of a novel dye of the anthraquinone series, according to which the 1-amino-4-chloranthraquinone-2,6 - disulfonic acid is condensed with m- acid. aminobenzoic acid.



       The new colorant corresponds to the following formula:
EMI0001.0014
    and dyed the animal fibers a reddish blue, not fading to, artificial light.



       Example: The following solution is prepared: 5.6 parts of m-aminobenzoic acid and 60 parts of water, neutralized with 3.2 parts of sodium hydroxide and 13 parts of 1-amino-4-chlor-anthraquinone are added -2,6-sodium disulfonate and 0.2 part copper powder and heat to 80 until condensation is complete. The dye is cleaned by adding salt which precipitates it, and filtered.

   The new colourant matches the formula and dyes the animal fibers a reddish blue, not fading in artificial light.
