Description
<B>Brevet additionnel</B> subordonné au brevet principal no . 236-390. 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-bromanthraqui- none-2,6-disulfonique avec la m-chloraniline.
Le nouveau colorant correspond à la for mule
EMI0001.0009
et teint les fibres animales en bleu rougeâtre, ne virant pas au rouge à la lumière artifi cielle.
<I>Exemple:</I> On chauffe ensemble à 80 : 15 parties de 1-amino-4-bromanthraquinone-2, 6- disulfonate de sodium, 3,9 parties de m-ehloraniline, 4,8 parties -de bicarbonate de sodium, 0,2 par tie de poudre -de cuivre, 60 parties d'eau, 15 parties d'alcool.
On verse la masse de condensation dans de l'acide dilué et sépare le nouveau colorant selon les méthodes connues.
Le colorant correspond à la formule
EMI0001.0018
et teint les fibres animales en bleu rougeâtre, ne virant pas au rouge à la lumière artifi- cielle.
<B> Additional patent </B> subject to main patent no. 236-390. Process for the preparation of a new dye of the anthraquinone series. The present invention relates to a process for the preparation of a new dye of the anthraquinone series, according to which 1-amino-4-bromanthraquinone-2,6-disulfonic acid is condensed with m-chloraniline .
The new dye corresponds to the formula
EMI0001.0009
and dyes the animal fibers a reddish blue, not turning red in artificial light.
<I> Example: </I> Heated together to 80: 15 parts of 1-amino-4-bromanthraquinone-2, 6- sodium disulphonate, 3.9 parts of m-ehloraniline, 4.8 parts of bicarbonate of sodium, 0.2 part of copper powder, 60 parts of water, 15 parts of alcohol.
The condensation mass is poured into dilute acid and the new dye separated according to known methods.
The dye corresponds to the formula
EMI0001.0018
and dyes the animal fibers a reddish blue, not turning red in artificial light.
