Description

  

  Verfahren zur     Darstenung    eines sauren     Farbstoffes    der     Anthrachinonreihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines sauren Farb  stoffes der     Anthrachitionreihe,    welches da  durch gekennzeichnet ist,     dass    man     ss'-Amino-          4'-methyldiphenylmethan-2-earbonsäure    mit       1-Amino-4-bromanthrachinon-2-sulfosäure    in  Form ihrer     Natriumsalze    in wässeriger Lösung  und     in    Gegenwart einer geringen Menge von       Kupferohlorär    kondensiert.  



  <I>Beispiel:</I>  40 Gewichtsteile     3-Amino-4'-methyldiphe-          nylmethan-2-carbonsäurechlorhydrat    werden in  <B>600</B> Gewichtsteilen Wasser unter Zusatz der  berechneten Menge Soda gelöst. Nachdem der  Lösung 40 Gewichtsteile     1-Amino-4-brom-          anthrachinon-2-sulfosaures    Natrium, 20 Ge  wichtsteile     Natriumbikarbonat    und 2     Ge-          wichtstei]eKupferchlorürzugefügt    sind, wird  das Gemisch zirka 20 Stunden unter Rühren  auf<B>50-60 0</B> erwärmt. Nach dieser Zeit hat    sich der Farbstoff als voluminöse Masse aus  geschieden.

   Man saugt ab und reinigt durch       Waschen        mit        warmer        10        %iger        Kochsalz-          lösung    und durch     Umlösen    aus verdünnter       Sodalösung.    Der Farbstoff liefert auf Wolle  und Seide klare, blaue Töne.



  Process for the production of an acidic dye of the anthraquinone series. The subject of this additional patent is a process for the preparation of an acidic dye of the anthraquinone series, which is characterized by the fact that one ss'-amino-4'-methyldiphenylmethane-2-carboxylic acid with 1-amino-4-bromoanthraquinone-2-sulfonic acid in the form their sodium salts condensed in aqueous solution and in the presence of a small amount of copper chloride.



  <I> Example: </I> 40 parts by weight of 3-amino-4'-methyldiphenylmethane-2-carboxylic acid chlorohydrate are dissolved in <B> 600 </B> parts by weight of water with the addition of the calculated amount of soda. After 40 parts by weight of 1-amino-4-bromo-anthraquinone-2-sulphonic acid, 20 parts by weight of sodium bicarbonate and 2 parts by weight of copper chlorine have been added to the solution, the mixture is stirred for about 20 hours to 50-60 ° / B> heated. After this time, the dye has separated out as a voluminous mass.

   It is suctioned off and cleaned by washing with warm 10% saline solution and by dissolving it from dilute soda solution. The dye produces clear, blue tones on wool and silk.
