  Verfahren zur Darstellung haltbarer und trockener Ammoniumphosphate. 
 EMI1.1 
 ungünstiges Verhältnis von Stickstoff zu Phosphorsäure zeigten. oder aber hygroskopisch waren, oder bei genügendem Ammoniakgehalte leicht beim Aufbewahren und Transportieren Ammoniakverluste ergaben. Diese Unzuträglichkeiten werden nach dem vorliegenden Ver- 
 EMI1.2 
 welchem durch Einwirkung von Ammoniak auf mit   Schwefelsäure   aufgeschlossene Phosphate ein phosphorsäure- und stickstoffhältiges Produkt erhalten wird.

   Dieses Produkt enthält 
 EMI1.3 
 Gehalt an wasserlöslicher Phosphorsäure zeigt einen ständigen Rückgang, so dass nicht nur citratlösliche, sondern auch dreibasische Phosphorsäure sich nach kurzem Lagern bildet, und   endlich   ist das Produkt stark hygroskopisch und infolgedessen nicht streu bar. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of durable and dry ammonium phosphates.
 EMI1.1
 showed an unfavorable ratio of nitrogen to phosphoric acid. or were hygroscopic or, if there was sufficient ammonia content, easily resulted in ammonia losses during storage and transport. These inconveniences are according to the present regulation
 EMI1.2
 which by the action of ammonia on phosphates digested with sulfuric acid a product containing phosphoric acid and nitrogen is obtained.

   This product contains
 EMI1.3
 The content of water-soluble phosphoric acid shows a steady decline, so that not only citrate-soluble but also tribasic phosphoric acid is formed after a short storage period, and finally the product is strongly hygroscopic and consequently cannot be scattered.

** WARNING ** End of DESC field may overlap beginning of CLMS **.
