Description

  

  Procédé de préparation     d'un    nouveau colorant acide     brillant    de la série       anthraquinonique.       Le présent brevet a pour objet un procédé  de préparation d'un nouveau colorant de la  série     anthraquinoniquo,    selon lequel on con  dense l'acide     1-amino-4-b.romanthraquinone-          2,6-disulfonique    avec     l'1-amino-3,4-diméthyl-          cyclohegane.     



  Le colorant ainsi obtenu a pour formule  
EMI0001.0009     
    il teint la laine et     les        fibres,    animales, les  fibres artificielles à base de     superpolyamides     en ton bleu verdâtre vif.  



  Les teintures qu'il fournit     sons;    égales,  résistantes à la, lumière et au lavage, et       stables    à la lumière     artificielle.            Exemple:       Les     parties    indiquées sont en poids.  



  On mélange<B>23,8</B> parties     d'1-amino-4-          bromanthraquinone-2,6-disulfonate    de potas  sium technique, 40 parties     d'1-amino-3,4-di-          m6thyl-cyclohexane,    6 parties de soude caus  tique     33%,    0,4     parties    de poudre de cuivre,  40 parties d'alcool et 200     parties    d'eau. On       agite    et chauffe à 55-65  en     faisant    passer  un lent courant     d'azote    et en     maintenant    la  même température jusqu'à ce que la masse en    réaction soit devenue bleue. On sépare le co  lorant formé selon les méthodes connues.

    Il se présente sous forme de     poudre    cristal  line bleue, se dissolvant facilement dans  l'eau en bleu     verdâtre,    sa solution dans       SO4H,    est incolore, mais vire au bleu rou  geâtre     intense    par adjonction de     p-formal-          déhyde.     



  Les quantités d'amine, d'alcali, de cata  lyseur, de diluant peuvent varier dans de  larges     limites.    L'introduction du     dérivé          anthraquinonique    peut se faire     aussi    par pe  tites portions au cours de quelques     heures.  



  Process for the preparation of a new bright acid dye of the anthraquinone series. The present patent relates to a process for the preparation of a novel dye of the anthraquinoniquo series, according to which 1-amino-4-b.romanthraquinone-2,6-disulfonic acid is con dense with 1-amino- 3,4-dimethyl-cyclohegane.



  The dye thus obtained has the formula
EMI0001.0009
    it dyes wool and animal fibers, artificial fibers based on superpolyamides in a bright greenish blue tone.



  The tinctures which it supplies are; equal, resistant to light and washing, and stable to artificial light. Example: Parts shown are by weight.



  Mix <B> 23.8 </B> parts of 1-amino-4-bromanthraquinone-2,6-disulfonate of technical potassium, 40 parts of 1-amino-3,4-dimethyl-cyclohexane , 6 parts of 33% causative soda, 0.4 parts of copper powder, 40 parts of alcohol and 200 parts of water. Stir and heat to 55-65 with a slow stream of nitrogen passing through and maintaining the same temperature until the reaction mass has turned blue. The colorant formed is separated off according to known methods.

    It is presented in the form of a blue crystal powder, easily dissolving in water in greenish blue, its solution in SO4H, is colorless, but turns to intense reddish blue by addition of p-formaldehyde.



  The amounts of amine, alkali, catalyst catalyst, diluent can vary within wide limits. The introduction of the anthraquinone derivative can also be done in small portions over the course of a few hours.
