Beschreibung
Zusammenfassung:	Calcium hydrogenphosphate dihydrate is applicable in the agricultural industry as forage. The method of its preparation presupposes continuity of the process, where the final product has a constant and uniform composition. According to the method, the precipitating mixture, derived by mixing concentrated hydrochloric acid and carbonate slurry, containing 300 to 500 g/l of CaCO3, with pH of 4.5 to 6, or by mixing distilling liquid from the soda production and carbonate slurry from the purification of raw brine, reacts with phosphorus-containing solution with P2O5 from 8 to 25 per cent, by weight, at a weight ratio of 5/1 to 10/1.
