Patentiert im Deutschen Reiche vom 6. April 1916 ab.Patented in the German Empire on April 6, 1916.
Für manche Kulturen, beispielsweise zur Hefezüchtung, ist die Anwendung klar wasserlöslicher Nährstoffe ganz bestimmter Zusammensetzung geboten. Bei der Herstellüng dieser Bedingung genügender phosphorsäurehaltiger Nährstoffe aus xien für den Großbetrieb allein in Frage kommenden natürlichen Phosphaten bietet die zu diesem Zweck erforderliche Trennung der Phosphorsäure vom Kalzium technische Schwierigkeiten. ,' Klar wasser lösliqhe Mischdünger ließen sich deshalb mit diesem Rohstoff nur mit so hohen Kosten gewinnen, daß ihre Ver-' wendung im Großbetrieb ausgeschlossen war.For some cultures, for example for yeast cultivation, the use of clearly water-soluble nutrients is very specific commanded. In the production of this condition, phosphoric acid containing sufficient Nutrients from xien natural for large farms alone Phosphates provide the separation of phosphoric acid required for this purpose from calcium technical difficulties. 'Clear water-soluble mixed fertilizer could therefore only be obtained with this raw material at such high costs that their use in large-scale operations was ruled out.
Es ist nun gefunden worden, daß man einen wasserlöslichen Mischdünger von den jeweiligen Verhältnissen anzupassender, in den weitesten Grenzen veränderlicher Zusammensetzung erhält, wenn man mit Schwefelsäure aufgeschlossenes Rohphosphat mit einer wäßrigen Lösung yon so viel Natriumbisulf at oder Natriumsulfat auslaugt, daß das Kalzium bis auf den geringen, der Löslichkeit des Kalziumsulf äts entsprechenden AnteilIt has now been found that a water-soluble mixed fertilizer can be adapted to the respective proportions in the The widest limits of variable composition are obtained when using sulfuric acid digested rock phosphate with an aqueous solution of as much sodium bisulfate or sodium sulfate leaches that the calcium down to the low, the solubility of the calcium sulfate corresponding proportion
as ungelöst bleibt. Man kann natürlich auch von vornherein eine bisulfathaltige Schwefelsäure oder Schwefelsäure und Natriumsulfat zum Aufschluß verwenden. Nach Abtrennung des Kalziumsulfats wird die Lösung, welche gemäß der Gleichunghe remains unsolved. Of course you can too from the outset a bisulfate-containing sulfuric acid or sulfuric acid and sodium sulfate use for digestion. After separating the calcium sulfate, the solution, which according to the equation

Gaswasser) von Eisen und Tonerde befreit, unter gleichzeitiger Neutralisation der entsprechenden Menge Phosphorsäure nitriert und das Ganze auf ein spez. Gewicht von etwa 1,5 eingeengt, Tn die heiße Lösung gibt man alsdann noch so viel Ammonsulfat oder Kaliumsulfat bzw. von beiden Salzen, als der gewünschten Zusammensetzung des Mischdüngers entspricht, und läßt erkalten. /essentially contains H 3 PO ,,, NaH 2 PO 4 and Na 2 SO 4 , freed from iron and alumina by introducing von.Ammoniakgas or adding an ammonia-containing liquid (concentrated gas water), nitrated while neutralizing the corresponding amount of phosphoric acid and that Whole on a spec. Weight of about 1.5 concentrated, then as much ammonium sulphate or potassium sulphate or of both salts as corresponds to the desired composition of the mixed fertilizer is added to the hot solution and allowed to cool. /
Das erhaltene Produkt läßt sich auf beliebige Feinheit bringen, ist sehr lagerfähig und bei Verwendung von Bisülfat an. Stelle freier Schwefelsäure besonders wohlfeil.The product obtained can be brought to any fineness and is very storable and when using bisulfate. Job Free sulfuric acid is particularly cheap.

Zudem bietet das erhältliche Produkt Nachteile, weil ■ es ständig gasförmige Salzsäure entwickelt und deshalb nur schwer versandfähig ist; auch stellt es kein klar, sondern ein nur teilweise lösliches Gemenge dar. Beim Auflösen in Wasser hinterbleiben Gips, Sand, Sesquiphosphate usw. Es enthält (wie■ ·· be viable where hydrochloric acid has no commercial value, which is only in exceptional cases the EaIl is. In addition, the available product offers Disadvantages because ■ it constantly evolves gaseous hydrochloric acid and is therefore difficult is dispatchable; nor does it represent a clear, but only a partially soluble mixture.

Die große Masse der vorhandenen Chloride schließt auch seine Verwendung für empfindliche Kulturen aus.ίο Superphosphates have significant proportions of heavy or completely insoluble ballast. The great bulk of the chlorides present also closes its use for sensitive crops.
Zur Gewinnung eines klar löslichen, i 7 Prozent P2O5 und 13 Prozent N enthaltenden Gemisches verfährt man wie folgt: 150 g Superphosphat mit 12,0 Prozent Gesamt- und 11,3 Prozent ,wasserlöslicher, bei 7,1 Pro-To obtain a clearly soluble mixture containing 7 percent P 2 O 5 and 13 percent N, proceed as follows: 150 g superphosphate with 12.0 percent total and 11.3 percent, more water-soluble, at 7.1 percent

Das Filtrat wird mit 30 g konz. Gaswasser von 19,0 Prozent NH3 versetzt, erwärmt, filtriert und auf etwa 1,5 spez.

The filtrate is concentrated with 30 g. Gas water of 19.0 percent NH 3 is added, heated, filtered and adjusted to about 1.5 spec. Weight evaporated. ■ After adding 30 g of ammonium sulphate, a mile is heated while stirring and the finished melt is drained to cool.
Das Ammonsulfat wird je nach dem Verwendungszweck des Düngers ganz, oder teilweise durch Kaliumsulfat ersetzt. Bei der Herstellung in größerem Maßstabe nimmt 35' man natürlich Waschlaugen aus früheren' Operationen statt Wasser zum Auslaugen des aufgeschlossenen Rohmaterials.The ammonium sulphate is wholly or partially depending on the intended use of the fertilizer replaced by potassium sulfate. When manufacturing on a larger scale, 35 'takes one of course wash liquors from previous' operations instead of water for leaching the unlocked raw material.
