Um Magnesiumphosphat darzustellen, bringt man Kalkphosphat durch schweflige Säure in Lösung und setzt eine dem gelösten Kalk entsprechende Menge Magnesiumsulfat zu und darauf nach der Filtration so viel Magnesiumoxyd, -Carbonat oder -Hydroxyd,' dafs gerade Magnesiumphosphat ausgefällt wird.In order to produce magnesium phosphate, lime phosphate is brought in by means of sulphurous acid Solution and adds an amount of magnesium sulphate corresponding to the dissolved lime and thereupon, after filtration, enough magnesium oxide, carbonate or hydroxide, just enough Magnesium phosphate is precipitated.
Die überstehende Lösung des Magnesiumsulfits wird in geeigneter Weise (durch Einblasen von Luft, durch Eisenoxyde oder Braunstein etc.) wieder in Sulfat übergeführt und zum Ueberführen des Kalkes einer zweiten Portion Kalkphosphat in Gyps benutzt. Auf diese Weise gelingt es, die angewendete schweflige Säure zweimal zu benutzen.The supernatant solution of the magnesium sulfite is removed in a suitable manner (by blowing in from air, through iron oxides or manganese dioxide, etc.) converted back into sulfate and a second portion of lime phosphate is used to convert the lime into gypsum. on In this way it is possible to use the sulphurous acid applied twice.
