Verfahren zur Darstellung von Natriumperborat.
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Darstellung von Natriumporhorat auf eine sehr glatte und wirtschaftlich ausserordentlich vorteilhafte Weise.
Behandelt man Lösungen oder Suspensionen von Natriumsuperoxyd in Wasser in geeigneter Weise mit Kohlensäure oder Alkalibikarbonaten, so erhält man eine Lösung, welche Natriumperkarbonat enthält. Trägt man in diese Lösung nun Alkaliborate ein, z. H. Natriummetaborat, so erhält man, falls man molekulare Mengen angewendet hat, einen Niederschlag von Natriumperborat in nahezu quantitativer Weise. Das ist umso über- raschender, als nicht anzunehmen war, dass von vorneherein eine vollständige Umsetzung von Natriulllperkarbonat in Natriumperborat stattfinden würde, weil die Körper schr ähnlich zusammengesetzt sind.
Ferner wird auf diese Weise das Alkali des Natriumsuperoxyds nicht entwertet,

lösung, die leicht anderweitig verwertet werden kann. An Stelle von Kohlensäure kann man auch vorteilhaft die kostenlos zu erhaltenden kohlensäurehaltigen Abgase verwenden. Natürlich kann auch nach anderen bekannten Verfahren z. H. nach dem Verfahren des D. R.-Patentes Nr. 145746 dargestelltes Natriumperkarbonat zur Umsetzung mit Alkaliboraten verwendet werden.
Durch folgendes Beispiel möge die ungefähre Arbeitsweise des neuen Verfahrens gezeigt werden.
Bei s pie 1 : In 3000 Teile Wasser werden 1560 Teile Natriumsuperoxyd eingetragen unter Zugabe von so viel Eis, dass keine Temperaturerhöhung stattfindet. Nun leitet man solange staubfreie, kohlensäurehaltige Abgase ein, bis kein freies Alkali sich mehr in Lösung befindet, wobei ein Überschuss an Kohlensäure nicht schadet. Hierauf gibt man eine konzentrierte Lösung von Natriummotaborat hinzu, die man sich z. R. aus 1240 Teilen Borsäure und 200 Teilen Atznatron hergestellt hat. Unter Rühren lässt man nun das Natriumperborat ausfallen und sorgt durch evontl. Zugabe von Eis und Eiswasser dafür, dass am

ist, dass alle Soda gelöst gehalten wird. Das ausgeschiedene Perborat wird in üblicher Weise getrennt und getrocknet.
Das Natriummetaborat kann man durch die entsprechende Menge Borax oder anderer Alkaliborate ersetzen. Das Natriumsuperoxyd lässt sich natürlich durch Natrium-Kaliumsuperoxyd oder Kaliumsuperoxyd orsetzen sofern die zur Bildung von Natriumperborat nötige Natriull1salzmrnge vorhanden ist, bezw. hinzugefügt wird, ebenso wie die Kohlensäure durch die entsprechende Menge Alkalibikarbonat ersetzt werden kann. Auch die Reihuufoige, in der man die Körper in Reaktion bringt, kann wechseln. Man kann

Process for the preparation of sodium perborate.
The subject of the present invention is a method for preparing sodium porhorate in a very smooth and economically extremely advantageous manner.
If solutions or suspensions of sodium peroxide in water are treated in a suitable manner with carbonic acid or alkali bicarbonates, a solution is obtained which contains sodium percarbonate. If you enter alkali borates in this solution, z. H. Sodium metaborate, if molecular quantities have been used, a precipitate of sodium perborate is obtained in an almost quantitative manner. This is all the more surprising as it could not be assumed that a complete conversion of sodium percarbonate into sodium perborate would take place from the outset, because the bodies are composed very similarly.
Furthermore, the alkali of sodium peroxide is not devalued in this way,
EMI1.1
solution that can easily be used elsewhere. Instead of carbonic acid, it is also advantageous to use the carbonated exhaust gases that can be obtained free of charge. Of course, by other known methods, for. H. sodium percarbonate prepared according to the method of D.R. Patent No. 145746 can be used for reaction with alkali borates.
The approximate mode of operation of the new method may be shown by the following example.
At pie 1: 1560 parts of sodium peroxide are added to 3000 parts of water while adding enough ice to prevent the temperature from increasing. Now, dust-free, carbonic acid-containing exhaust gases are introduced until there is no more free alkali in solution, an excess of carbonic acid not being harmful. Then you add a concentrated solution of sodium motaborate, which you z. R. made of 1240 parts of boric acid and 200 parts of caustic soda. The sodium perborate is now allowed to precipitate with stirring and evontl. Adding ice and ice water for that on
EMI1.2
is that all soda is kept dissolved. The perborate which has separated out is separated and dried in the usual way.
The sodium metaborate can be replaced by the appropriate amount of borax or other alkali borates. The sodium superoxide can of course be replaced by sodium-potassium superoxide or potassium superoxide, provided that the amount of sodium salt necessary for the formation of sodium perborate is present or is added, just as the carbonic acid can be replaced by the appropriate amount of alkali bicarbonate. The Reihuufoige, in which the body reacts, can also be changed. One can
