Abstract: Roztok kyseliny trihydrogenfosforečné se
částečně zneutralizuje uhličitanem vápenatým
a zamoniakalizuje. Ze vzniklé suspenze se
oddělí sraženina a zbylý roztok se sráží
roztokem vodorozpustné vápenaté soli. Po
opětovném oddělení sraženiny se zbylý roztok
regeneruje za použití oxidu nebo hydroxidu
vápenatého nebo jejich směsi na amoniak
a roztok vápenaté soli, které se použijí
jako recykl. Sraženina se po promytí,
vysušení případně dehydratuje tepelným
zpracováním, pokud její složení neodpovídá
požadovanému produktu. Přitom je výhodné
přidávat během výroby stabilizátory zpomalující
dehydrataci a hydrolýzu produktu.
Rovněž je výhodné přidávat během výroby
látky ovlivňující tvrdost výrobku.
Produkt je vhodný k použití jako obohacující
přísada krmných směsí v živočišné
výrobě.
