behandelt werden, beispielsweise zur Verwertung des Stickstoffes als Ammoniak und der vert bleibende Rückstand, welcher hauptsächlich aus Natriumkarbonat besteht, kann zur Fällung eines weitereWeiles des Bariums im nächsten Arbeitsgang verwendet werden.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Ferrocyanid in Kristallen, dadurch gekennzeichnet, dass-eine insbesondere Natrium-Ferroeyanid und Natriumkarbonat enthaltende Lösung bei zirka 800 C bis zum Kristallisationspunkte eingedampft und langsam bis zur Temperatur der maximalen Löslichkeit des Natriumkarbonates abgekühlt wird, wodurch man die Ausscheidung von praktisch reinem Ferrocyanid erzielt, bei welcher Temperatur sodann die übrige Flüssigkeit abgezogen wird, bevor noch eine merkliche Ausscheidung von Natriumkarbonatkristallen ein- treten könnte.

can be treated, for example to utilize the nitrogen as ammonia, and the remaining residue, which mainly consists of sodium carbonate, can be used for the precipitation of a further portion of the barium in the next operation.
PATENT CLAIMS:
1. A process for the production of ferrocyanide in crystals, characterized in that a solution containing in particular sodium ferroeyanide and sodium carbonate is evaporated at about 800 C to the crystallization point and slowly cooled to the temperature of the maximum solubility of the sodium carbonate, whereby the excretion of obtained practically pure ferrocyanide, at which temperature the remaining liquid is then drawn off before a noticeable precipitation of sodium carbonate crystals could occur.
