KAISERLICHESIMPERIAL
Düngemittel.Fertilizer.
Gemäß Patent 299284, Zusatz zum Patent 286491, sollen die aus Harnstoff und Superphosphaten erhältlichen Produkte als Düngemittel verwendet werden. Diese Produkte können, wie sich gezeigt hat, unter Umständen beim Lagern feucht werden, wodurch ihre Streufähigkeit beeinträchtigt wird.According to patent 299284, addendum to patent 286491, those made from urea and superphosphates available products can be used as fertilizers. These products can, as has been shown, possibly become damp during storage, which makes their Throwing power is impaired.
Es wurde nun gefunden, daß dies vermieden wird, wenn man solche Produkte verwendet, die aus Harnstoff und Superphosphaten erhältlich und noch mit gasförmigem Ammoniak behandelt sind. Diese Behandlung kann während des Mischens oder auch nach-. träglich geschehen, und man führt sie im allgemeinen so. weit, daß das Produkt keine saure Reaktion mehr zeigt. Das Ammoniak kann auch in Form von Ammoniumsalzen flüchtiger Säuren, also z. B. als Carbamat verwendet werden, auch kann, man gleichzeitig trockene Luft usw. überleiten.It has now been found that this is avoided by using such products which are available from urea and superphosphates and are still treated with gaseous ammonia. This treatment can be used during mixing or after-. happen dearly, and they are generally carried out so. far that the product no longer shows an acidic reaction. The ammonia can also be in the form of ammonium salts of volatile acids, e.g. B. used as a carbamate also can, one can pass dry air etc. at the same time.
Man hat zwar schon aus Monocalciumphosphat und Ammoniak ein Ammoniummonocalciumphosphat hergestellt, doch bot dies keine Anhaltspunkte dafür, daß die nach dem vorliegenden Verfahren verwendeten Produkte gerade " durch Zusatz von Ammoniak eine bessere Streufähigkeit erlangen würden, da bei ihnen schon vorher eine basische Substanz, der Harnstoff, zugegen war.It is true that one already has an ammonium monocalcium phosphate from monocalcium phosphate and ammonia produced, but this offered no evidence that the after present processes used products just "by adding ammonia a would achieve better throwing power, since they already have a basic substance, the urea, was present.
