Description
Düngemittel In dem Hauptpatent 498 983 ist ein Verfahren zur Herstellung eines mit Wasser sich langsam zersetzenden phosphorsäure- und kieselsäurehaltigen Düngemittels beschrieben, bei dem kieselsäurehaltiges Material zusammen mit einer zur Lösung der Kieselsäure unzureichenden Menge Phosphorsäure erhitzt und das erhaltene Produkt gegebenenfalls noch mit anderen Düngemitteln vermischt wird.Fertilizers The main patent 498 983 describes a process for the production of a phosphoric acid and silicic acid-containing fertilizer which decomposes slowly with water, in which the silicic acid-containing material is heated together with an insufficient amount of phosphoric acid to dissolve the silicic acid and the product obtained is mixed with other fertilizers if necessary .
Es wurde nun gefunden, daß man vorteilhaft zu einem Düngemittel gelangt, das außer Phosphorsäure und Kieselsäure noch Stickstoff enthält, wenn man die durch Erhitzen von kieselsäurehaltigem Material mit Phosphorsäure erhaltene Masse mit Ammoniak behandelt. Das so gewonnene Düngemittel ist gut lagerfähig und weist neutrale Reaktion auf. Durch Änderung der anzuwendenden Mengenverhältnisse der Ausgangsstoffe kann das Stickstoff - Phosphorsäure - Kieselsäure-Verhältnis im Endprodukt weitgehend variiert werden; ebenso können auch hier noch andere Düngemittel zugesetzt werden. Beispiel Ioo kg fein gemahlener Flußsand werden bei gewöhnlicher Temperatur mit 3oo kg einer 7o°/oigen Phosphorsäure unter Rühren innig vermischt und darauf in einem Muffelofen auf 35o° so lange erhitzt, bis kein Wasserdampf mehr entweicht. Nach dem Abkühlen wird die erhaltene Masse grob zerkleinert und mit gasförmigem Ammoniak bis zur Sättigung behandelt. Das Produkt wird sodann fein gemahlen und kann als Düngemittel unmittelbar verwendet werden.It has now been found that a fertilizer is advantageously obtained which, in addition to phosphoric acid and silicic acid, also contains nitrogen if you go through it Heating of siliceous material with phosphoric acid obtained mass with Treated with ammonia. The fertilizer obtained in this way can be stored well and is neutral Reaction to. By changing the proportions of the starting materials to be used the nitrogen - phosphoric acid - silica ratio in the end product can largely be reduced be varied; other fertilizers can also be added here as well. Example 100 kg of finely ground river sand are used at ordinary temperature 300 kg of a 7o% phosphoric acid are intimately mixed with stirring and then poured into heated in a muffle furnace to 35o ° until no more water vapor escapes. After cooling, the mass obtained is roughly crushed and mixed with gaseous Ammonia treated to saturation. The product is then finely ground and can be used directly as a fertilizer.
