Man kann z.

   F. eine  wässerige Lösung von 1 Hol 3 .     6-Diamino-          akridinchlorid    mit einer wässerigen Lösung  von mehr als 1     Mol        Trypanblau    versetzen.  Ferner kann man zunächst das Salz des 3.     6-          Diamino-akridinchlorids    mit     Trypanblau    her  siellen und dann     -dieses    Salz in einer Lösung  von     Trypanblau    auflösen.    Die so hergestellte Lösung ist beständig  und für Injektionen therapeutisch verwertbar.

    <I>Beispiel:</I>  35 Liter einer 1.     %igen    Lösung von 3.     6-          Diamino-akridinchlorid    werden vereinigt mit  70 Liter einer 1 %     igen        Trypanblaulösung.     Man saugt ab, wäscht mit etwas Wasser und  schlämmt den Niederschlag mit Wasser zu  einer Paste<B>(</B>17,5 kg) an. Von dieser Paste  werden 2 kg mit 16 kg einer 1 %     igen        Try-          panblaulösung    bei 70   C gut verrührt; man  erhält so eine klare. grün gefärbte Lösung.



  Process for the preparation of an aqueous solution of the salt of 3.G-Dia.mino-akridin with the dye from 1 hol tetrazo-o-tolidine and 2 hol 1-amino-8-naphtol-3. 6-disulfonic acid e.

      The present invention relates to a process for the preparation of an aqueous solution of the salt of 3. 6-diamino-acridine with the dye from 1 mol tetrazo-o-tolidine and 2 mol 1-amino-8-naphtol-3. 6- disulfonic acid (trypan blue), which is characterized by the fact that you click on 3.

       6-Dia, mino-acridine chloride the dye from 1 mole of tetr-azo-o-tolidine and 2 moles of 1-amino-8-naphthol-3. 6-disulfonic acid is allowed to act and the reaction product dissolves in an aqueous solution of the dye of 1 mol of tetrazo-o-tolidine and 2 mol of 1-amino-8-naphthol-3,6-disulfonic acid. You can z.

   F. an aqueous solution of 1 hol 3. Add 6-diamino acridine chloride to an aqueous solution of more than 1 mol of trypan blue. In addition, you can first sielle the salt of 3. 6- diamino-acridine chloride with trypan blue and then dissolve this salt in a solution of trypan blue. The solution produced in this way is stable and can be used therapeutically for injections.

    <I> Example: </I> 35 liters of a 1.% solution of 3. 6- diamino-acridine chloride are combined with 70 liters of a 1% trypan blue solution. It is filtered off with suction, washed with a little water and the precipitate is slurried with water to form a paste (17.5 kg). 2 kg of this paste are mixed well with 16 kg of a 1% trypan blue solution at 70 ° C .; you get a clear one. green colored solution.
