Description
In der Patentschrift 313271 ist ein Verfahren zur Verwertung der Endlaugen -der Kalifabriken und des Harns beschrieben, in dem man Ammoniumsalze: herstellt. Das Verfahren besteht darin, daß man den" Harn mit den chlormagnesiumhaltigen Endlaugen der Kalifabriken erhitzt, wobei sich Ammoniumsalze bilden. Um diesen Zweck.zu erreichen, genügt es, derartige Mengen von Endlaugen zu verwenden, daß auf 1 Molekül Harnstoff ι Molekül Chlormagnesiüm vorhanden ist (siehe die Umsetzungsgleichung in der Patentschrift 31.3271). Das vorliegende Verfahren besteht nun darin, daß man größere Mengen der Endlauge verwendet, als. dem molekularen Verhältnis von Chlormagnesium und Harnstoff entspricht, und zwar SO' viel, daß, abgesehen von der beschriebenen Einwirkung von Chlormagöesium auf Harnstoff, noch genügend Chlormagnesium' vorhanden ist, um, mit einem Teil des gebildeten Chlorammoniums oder mit dem gesamten Ammonsalz das DoppelsalzIn patent specification 313271 is a method for the recovery of the final liquors from the potash factories and the urine, in to which ammonium salts: are produced. The procedure is that you have the "urine with the final liquors containing magnesium chloride from the potash factories are heated, forming ammonium salts form. In order to achieve this purpose, it is sufficient to use such amounts of final caustic solutions to use that on 1 molecule of urea ι Molecule of chloromagnesium is present (see the conversion equation in the patent 31.3271). The present method now consists in the fact that one larger quantities the final liquor used as. corresponds to the molecular ratio of chlorine magnesium and urea, namely SO 'much that, apart from the described action of chloromageesium on urea, still sufficient Chloromagnesium 'is present around, with some of the chlorammonium formed or the double salt with the entire ammonium salt

Die Ausscheidung des Doppelsalzes erfolgtThe double salt is excreted
' nach entsprechend1 weitem Eindampfen ohne Schwierigkeiten, da die Löslichkeit des Doppelsalzes (1: 6) bedeutend geringer ist als die der Bestandteile. Wenn man-so viel Chlormagnesium angewendet hat, daß die ganze Menge des Chlormagnesiums in das Doppelsalz umgewandelt' ist, kann man die übrigbleibende Lösung ohne Schaden in die öffentliehen Wasserläufe ablassen, da sie keine erhebliche Menge von Chlor mehr 'enthält.. Ist noch ein Überschuß an Chlorammonium vorhanden, so kann man die Lösung mit neuen Mengen Harn verarbeiten. .After 1 further evaporation without difficulty, since the solubility of the double salt (1: 6) is significantly lower than that of the constituents. When you have used so much magnesium chloride that the whole amount of magnesium chloride has been converted into the double salt, you can drain the remaining solution into public watercourses without damage, since it no longer contains any significant amount of chlorine If there is an excess of chlorammonium, the solution can be processed with new amounts of urine. .
Ein etwaiger Überschuß von Chlormagnesiüm über die zur Bildung des Doppelsalzes erforderliche Menge verbleibt in der Mutter-' lauge.Any excess of chlorine magnesia over that required for the formation of the double salt required amount remains in the mother liquor.
Der durch das vorliegende Verfahren eintretende Mehrverbrauch an Endlauge' ist für die Kalifabriken vorteilhaft, da es letzteren hauptsächlich darauf ankommt, die Endlauge unschädlich zu machen und zu verwerten.The additional consumption of final liquor resulting from the present process is for the potash factories are advantageous, since the latter mainly depends on the final liquor to render harmless and to recycle.
Die Ausführung des Verfahrens . kann in folgender Wei&e geschehen.The execution of the procedure. can be done in the following ways.
