PATENT-ANSPRUCH : Verfahren zur Darstellung eines von Kalziumsulfit freien Dikalziumphosphats, dadurch gekennzeichnet, dass man eine Lösung von Trikalziumphosphat in wässeriger, schwefliger Säure oder den durch Kochen dieser Lösung erhaltenen kalziumsulfitllaltigen Niederschlag mit Monokalziumphosphat oder einer Mineralsäure so lange kocht, bis die schweflige Säure ausgetrieben ist. PATENT CLAIM: Process for preparing a calcium sulfite-free dipicalcium phosphate, characterized in that a solution of tricalcium phosphate in aqueous, sulphurous acid or the calcium sulphite-containing precipitate obtained by boiling this solution is boiled with monocalcium phosphate or a mineral acid until the sulphurous acid is expelled.
