Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 193354. Verfahren Herstellung eines Mischdüngers. Im Hauptpatent ist ein Verfahren zur Herstellung eines Mischdüngers beschrieben, der zur Hauptsache aus Rohphosphaten und schwefelsaurem Ammoniak besteht, wobei dem Gemisch von Rohphosphat und Ammon- sulfat ein geringer Prozentsatz eines freie Phosphorsäure oder wasserlösliche Salze der selben enthaltenden Stoffes zugesetzt wird, zum Zwecke, Ammoniakverluste zu verhin dern.
Es wurde nun gefunden, dass ein Misch dünger, der Knochenmehl und ein Ammo- niumsalz, insbesondere Ammonsulfat, sowie geringe Mengen eines freie Phosphorsäure oder wasserlösliche Salze derselben enthal tenden Stoffes enthält, die gleichen Wirkun gen auszuüben imstande ist und die gleichen Vorteile bietet, wie der gemäss dem Verfah ren des Hauptpatentes hergestellte Misch dünger. Auch hier haben die zusätzlichen Phosphate die Wirkung, frei werdendes Am moniak sofort in Form von Ammonphosphat bezw. Doppelsalzen desselben zu binden.
Gegenstand des vorliegenden Patentes ist also ein Verfahren zur Herstellung eines zur Hauptsache aus Knochenmehl und einem Ammonsalz bestehenden Mischdüngers, da durch gekennzeichnet, dass man dem Gemisch von Knochenmehl und Ammonsalz eine ge ringe Menge eines freie Phosphorsäure oder wasserlösliche Salze derselben enthaltenden Stoffes zusetzt.
Der Dünger kann beispielsweise 4 kg Knochenmehl, 1,6 kg Ammonsulfat und 0,08 kg Superphosphat mit<B>18%</B> P205 ent halten.
<B> Additional patent </B> to main patent no. 193354. Process Production of a mixed fertilizer. The main patent describes a process for the production of a mixed fertilizer, which mainly consists of rock phosphates and sulfuric acid ammonia, a small percentage of free phosphoric acid or water-soluble salts of the same containing substance being added to the mixture of rock phosphate and ammonia, for the purpose of ammonia losses to prevent.
It has now been found that a mixed fertilizer containing bone meal and an ammonium salt, in particular ammonium sulfate, as well as small amounts of a free phosphoric acid or water-soluble salts of the same containing substance, is able to exert the same effects and offers the same advantages as the mixed fertilizer produced according to the process of the main patent. Here, too, the additional phosphates have the effect of immediately releasing ammonia in the form of ammonium phosphate respectively. To bind double salts of the same.
The subject of the present patent is therefore a process for the production of a mixed fertilizer consisting mainly of bone meal and an ammonium salt, characterized in that a small amount of a substance containing free phosphoric acid or water-soluble salts thereof is added to the mixture of bone meal and ammonium salt.
The fertilizer can contain, for example, 4 kg bone meal, 1.6 kg ammonium sulfate and 0.08 kg superphosphate with <B> 18% </B> P205.
