Das nach mehrmaligem Gebrauche erschöpfte Silikat erreicht seine ursprünglichen harteentziehenden Eigenschaften wieder, wenn es analog den Aluminiumdoppelsilikaten mit Kochsalz regeneriert wird. 



   Bei der Herstellung von Mitteln" zum Enthärten des Rohwassers hat sich gezeigt. dass man durch Erhitzen von   Alka1isilikatlösung   mit Natriumphosphatlösung - welche Reaktion in der oben angeführten Literaturangabe Gmelin-Kraut"Handbuch der anorganischen Chemie" nich angeführt ist - gegenüber den anderen Alkaliverbindungen, wie Chlornatrium Natriumsulfat oder Natriumazetat eine wesentlich höhere Ausbeute an Enthärtungsmitteln erhält, wodurch gerade die Verwendung von Natriumphosphat zur Darstellung des Enthärtungsmittels in ökonomischer Hinsicht am geeignetsten wird. 



   Zu den Versuchen, die als Vergleichsversuche ausgeführt wurden, wurden einmal als Zusatzmittel zu der Alkalisilikatlösung Lösungen von Natriumsulfat, Chlornatrium oder Natriumazetat genommen, deren Verwendung zur Erzeugung eines Niederschlages in Alkalisilikatlösungen bekannt ist und das andere Mal   Natriumphosphatlösung.   Das Resultat war folgendes :
I.

   Beim Zusatz von Natriumsulfat, Chlornatrium oder Natriumazetat zu Wasserglas ergaben :
1. 3 kg Wasserglas mit 100 l 10%iger Neutralsalzlösung zusammengebracht. 200 g
Niederschlag, was   6#7% des angewandten Wasserglases entspricht   ;   2. 4, kg Wasserglas   mit 100   l   10%iger Neutralsalzlösung zusammengebracht, 300 g
Niederschlag, was   7#5% des   angewandten Wasserglases entspricht ; ka Wasserglas mit 100 1 10% iger Neutralsalzlösung 400 g Niederschlag, was
8% des angewandten Wasserglases entspricht. 



   II. Beim Zusatz von Natriumphosphat zu Wasserglas ergaben :
1. 3 kg Wasserglas mit 1UO l 10%iger Natriumphosphatlösung zusammengebracht. 



   750   9   Niederschlag, welche Menge 25% des Gewichtes des angewandten Wasserglases entspricht ;
2.4 kg Wasserglas mit 1UO   l   10%iger Natriumphosphatlösung zusammengebracht,
1050 g Niederschlag, was 26% des angewandten Wasserglases entspricht. 



   3. 5 kg Wasserglas mit 100 l 10%iger Natriumphosphatlösung 2300 g Niederschlag.

   Alls den   angefuhrten   Zahlen geht deutlich hervor, dass die Abscheidung des Ent-   hrtungsmtttels   aus dem Wasserglas durch Natriumphosphatlösung eine quantitativ bedeutend reichlicher ist als mittels der früheren Neutralsalze, was in wirtschaftlicher Hinsicht von grossem Vorteile ist.

The silicate, which is exhausted after repeated use, regains its original hard-removing properties when it is regenerated with common salt, analogous to the aluminum double silicates.



   In the production of agents "for softening the raw water, it has been shown that by heating alkali silicate solution with sodium phosphate solution - which reaction is not mentioned in the above Gmelin-Kraut" manual of inorganic chemistry "- compared to other alkali compounds such as sodium chloride Sodium sulfate or sodium acetate gives a significantly higher yield of softening agents, which makes the use of sodium phosphate for the preparation of the softening agent the most suitable from an economic point of view.



   In the experiments which were carried out as comparative experiments, solutions of sodium sulfate, sodium chloride or sodium acetate were used as additives to the alkali metal silicate solution, the use of which is known for producing a precipitate in alkali metal silicate solutions, and the other time sodium phosphate solution. The result was the following:
I.

   When sodium sulphate, sodium chloride or sodium acetate were added to water glass:
1. 3 kg of water glass combined with 100 l of 10% neutral salt solution. 200 g
Precipitation, which corresponds to 6% 7% of the water glass used; 2. 4. kg of water glass combined with 100 l of 10% neutral salt solution, 300 g
Precipitation, which corresponds to 7 # 5% of the water glass used; ka water glass with 100 1 10% neutral salt solution 400 g of precipitate, what
8% of the water glass used.



   II. When sodium phosphate was added to water glass:
1. 3 kg of water glass combined with 1UO l of 10% sodium phosphate solution.



   750 9 precipitation, which amount corresponds to 25% of the weight of the water glass used;
2.4 kg water glass combined with 1UO l 10% sodium phosphate solution,
1050 g of precipitate, which corresponds to 26% of the water glass used.



   3. 5 kg of water glass with 100 l of 10% sodium phosphate solution 2300 g of precipitate.
 EMI2.2
 



   All of the above figures clearly show that the separation of the detergent from the water glass with sodium phosphate solution is quantitatively significantly more abundant than with the earlier neutral salts, which is of great economic advantage.
