Description

Verfahren zur Darstellung eines trockenen Düngemittels Es ist bekannt, Phosphorsäure mit Salzen in wässeriger Lösung zu kuppeln.Method of preparing a dry fertilizer It is known Coupling phosphoric acid with salts in aqueous solution.

Demgegenüber wurde gefunden, daß, wenn man nebelförmige Phosphorsäuren bei der hierbei notwendigen Menge Wasserdampf in einem geeigneten Apparat (Turm oder drehbare Trommel) auf sehr feinkörnige Kreide einwirken läßt und hierbei die Temperatur auf etwa iio bis 12o° C hält, folgende Umsetzungen stattfinden: CaCO3 + 2 HP03= Ca(P03)2 + H20 -f- C02 (z) Ca(PO3)2 -;- z H20 = (2) Wenn, wie beschrieben, .verfahre. wird, erhält man ein trockenes, streubares Produkt, das bis zu 6o °/o P"0, enthalten kann. Dieses Salz ist bis zu go °/o wasserlöslich rund nur ro°io davon sind citratlös.lichePhosphorsäure.On the other hand, it has been found that if nebulous phosphoric acids are allowed to act on very fine-grained chalk with the required amount of steam in a suitable apparatus (tower or rotating drum) and the temperature is kept at about 110 to 120 ° C., the following reactions take place: CaCO3 + 2 HP03 = Ca (P03) 2 + H20 -f- C02 (z) Ca (PO3) 2 -; - z H20 = (2) If, as described, proceed. a dry, scatterable product is obtained which can contain up to 60% P "0. This salt is up to 100% water-soluble, around only 100% of which are citrate-soluble phosphoric acid.

Wird die Reaktion jedoch bei .4oo bis 6oo° C durchgeführt, so geht die Umsetzung nach Reaktion i. Das so erhaltene Produkt muß nachträglich mit Wasserdampf behandelt werden, gibt dann aber ebenfalls ein gut streubares Produkt.However, if the reaction is carried out at .400 to 600 ° C., it works the implementation after reaction i. The product obtained in this way must subsequently be steamed are treated, but then also gives a product that is easy to spread.

Das Düngemittel ist leicht herstellbar und enthält keine den Boden schädigende Bestandteile.The fertilizer is easy to manufacture and does not contain the soil harmful components.
