Description

Verfahren zur Herstellung eines Wasser nicht anziehenden Mischdüngers aus Kalziumnitrat. Bekanntlich besitzt der hauptsächlich in Norwegen hergestellte Kalksalpeter den Nachteil, stark wasseranziehend zu sein. Man hat ihn zur Aufhebung der Wasseranziehung mit löslichen Sulfaten der Alkalien usw. gemischt, wobei sich Gips und das Nitrat des zugesetzten Alkalis bildeten. Durch diesen Sulfatzusatz hat aber die Düngewirkung des Kalksalpeters keine Erhöhung erfahren.Process for the production of a mixed fertilizer which does not attract water from calcium nitrate. As you know, owns the one mainly produced in Norway Calcium nitrate has the disadvantage of being highly water-attracting. He has to be repealed the attraction of water mixed with soluble sulphates of the alkalis, etc., being Gypsum and the nitrate of the added alkali formed. With this addition of sulfate but the fertilizing effect of calcium nitrate has not experienced any increase.

Nach vorliegender Erfindung werden Alkaliphosphate dem Kalksalpeter in solchen Mengen zugegeben, daß das Alkali die N03 Ionen abzusättigen vermag. Es hat sich gezeigt, daß bei der Verwendung sowohl von Natriumphosphat als 'auch von Kaliumphosphat eine Umsetzung unter Bildung der nicht oder wenig wasseranziehend wirkenden Alkalinitrate und von Mono- bzw. Dikalziumphosphat stattfindet.According to the present invention, alkali phosphates become calcium nitrate added in such amounts that the alkali is able to saturate the NO3 ions. It has been shown that when using both sodium phosphate and 'from Potassium phosphate a reaction with the formation of the non-or little water-attracting acting alkali nitrates and of mono- or di-calcium phosphate takes place.

Je nachdem, ob man einen schnell oder langsam wirkenden Phosphatdünger haben will, kann man Mono- oder Dialkaliphosphat verwenden. Eine besonders hochwertige Mischung ist die von i Mol. Kalziumnitrat mit 2 Mol. saurem Kaliumphosphat.Depending on whether you are using a fast or slow acting phosphate fertilizer you can use mono- or dialkali phosphate. A particularly high quality Mixture is that of 1 mole of calcium nitrate with 2 moles of acid potassium phosphate.
